Refactors door/window/railing/roof onto shared mixins from bim/parametric_lifecycle.py (FeatureModifierEditMixin and PathPreservingEditMixin); stair gets the lock-gizmo refactor and frame-cache integration. Behavior preserved. Adds BaseParametricGizmoGroup._prime_frame_caches so the parametric gizmos stop re-deriving preferences, view direction, and billboard rotation per frame; reorders poll() to short-circuit on the cheapest predicate first. Adds the icon library + BillboardingGizmoGroupMixin that the wall feature in the next commit will consume.

Removed the dead copies; runtime behavior unchanged (the live versions were already the kept ones). * bim/__init__.py's `_parametric_gizmo_preference_classes` docstring named the wrong link in the import chain (`tool.blender → bim.ifc`). The real chain is `tool/ifc.py` (and ~6 other tool/* modules) which import `from bonsai.bim.ifc import IfcStore` at module load. Updated docstring to cite that root cause and the architectural fix (move `IfcStore` out of `bim/`). * tool/blender.py's `from bonsai.bim.ifc import IFC_CONNECTED_TYPE` carried a 5-line comment claiming it was "lazy" to avoid a circular load. The import sits inside an `if TYPE_CHECKING:` block with `from __future__ import annotations` — it never runs at runtime regardless. Comment removed; the TYPE_CHECKING guard is self-explanatory.

Wall enters tool.Parametric.EDIT_TYPES, so save-time auto-commit, GizmoPreferencesWall registration, and the in-progress-edit predicates all light up automatically through the registry plumbing landed two commits back. The three-layer commit model (drag -> BIMWallProperties -> bmesh preview -> Finish -> single ifc.run) means dragging a handle through hundreds of intermediate values produces zero extra IFC entities. A no-op enable->finish round-trip is byte-identical. The snapshot diff in FinishEditingWall skips unchanged params. _commit_active_wall_edit_if_any ensures cursor-anchored operators see committed geometry, not the draft preview box. Also lands the `prompt_auto_commit_parametric_edits` BoolProperty on BIM_ADDON_preferences (consumed by the auto-commit dialog landed in the framework commit) and refactors `draw_{door,window,stair}_gizmo_parameters` into a shared `_draw_parametric_gizmo_parameters` helper that the new `draw_wall_gizmo_parameters` reuses. This commit and the framework commit are stacked - the framework commit references the BoolProperty defined here, so they must land together. Tests cover pure math (core/test_model.py), DimensionGizmoConfig text formatter, GizmoWallExtendVertically.poll() preconditions, and the refresh_post_commit cache-invalidation regression. BDD scenarios in model.feature cover the edit triad, auto-commit on save, and the two-object gizmos. Documentation added to creating_walls.rst.

Switch to ``billboarded_at(world_pos, billboard_rot, scale)`` where ``world_pos = mw @ local_pos``: translate to world space first, then apply the billboard rotation independently of the object's rotation. This matches the manual pattern the base class's ``update_editing_gizmos`` already uses for validate/cancel/cycle for exactly this reason. Drops the now-stale workaround docstring on ``GizmoWallEdition._update_icon_row_extras`` that documented why it bypassed ``set_icon_gizmo_position`` — the helper does the right thing now. Adds ``test/bim/module/model/test_stair_gizmos.py`` as the regression guard: parametrised over six rotation angles, asserts that the rotation part of the resulting matrix equals ``billboard_rot`` (no contribution from ``mw``'s rotation) and that the translation lands at ``world_pos``. Also exercises ``set_icon_gizmo_position`` end-to-end via a stub gizmo to catch the exact shape of the previously-broken call site.

Downstream consumers that want the same math without round-tripping through an IFC file (Blender gizmo previews, viewport drafts) now drive compute_X directly. Future add_X_representation work in the geometry API is encouraged to follow the same shape — a sibling compute_X function + thin IFC wrapper. The railing_type parameter is dropped from the signature — only WALL_MOUNTED_HANDRAIL was ever supported, so the kwarg was dead. The Bonsai railing-modifier caller is updated in the same commit to stop passing it; without that update Bonsai's finish_editing_railing_path raises TypeError on the first edit. RailingSupport and WallMountedHandrailGeometry use @dataclass(slots=True) — they're constructed N-per-cap during arc sampling, so the per-instance overhead matters. Public symbols (RailingSupport, TERMINAL_TYPE, WallMountedHandrailGeometry, compute_wall_mounted_handrail_geometry, add_railing_representation) re-exported from ifcopenshell.api.geometry.

The @interface declarations are empty-bodied; concrete implementations land in the per-service tool/* commits below. Keeping the contract in core lets core/* helpers and tests reference the surface without importing the concrete tool modules. Moves get_decomposition_relationships + recreate_decompositions off tool.Root onto the new tool.Duplicate (extraction of duplicate-aware behaviour into its own service).

Owns the BBIM_Array pset graph navigation (constrain_children_to_parent, remove_constraints, get_modifiers_data, get_children_objects, get_all_children_objects, get_child_layer_index, bake_children_transform), plus the Blender-side CHILD_OF constraint lifecycle that ties each child replica to its parent's transform. Array's own module gives the parent/child semantics a clean home — array behaviour was previously scattered between tool.Blender.Modifier and ad-hoc helpers in bim/module/model/array.py.

the duplicate-aware bookkeeping of "before duplication, what relations did this graph have, and how do I restore them on the new copies?" deserves its own home. The split was already declared on core/tool.py (C2); this commit lands the concrete tool.Duplicate implementation. tool.Root keeps its own copies of the methods on v0.8.0's tool/root.py during this PR so callers in bim/module/spatial/operator.py keep working at runtime; the Root cleanup lands in PR4 alongside the caller updates.

Each feature registers a ParametricObject spec declaring its enable/finish/cancel op names, props accessor, regen callback, and is_element_type predicate. Public surface: * tool.Parametric.WALL / SLAB / DOOR / WINDOW / RAILING / ROOF / STAIR / PIPE_SEGMENT / DUCT_SEGMENT — typed accessors per feature. * tool.Parametric.is_wall / is_door / is_window / is_railing / is_roof / is_stair — element-type predicates that move off tool.Blender.Modifier into the parametric registry. The next commit adds backward-compat shims on tool.Blender.Modifier so v0.8.0 callers keep working. * tool.Parametric.is_object_editing(obj) — returns the registered feature an object is currently editing, or None. * tool.Parametric.run_bim_op(op_name) — invoke a parametric op by bl_idname. * tool.Parametric.heal_stale_edit_flags — clear is_editing flags on file load so a saved-mid-edit project doesn't leave gizmos poll-locked. * supports_build_edit_lifecycle field on ParametricObject — declares whether the feature implements the build/edit/cancel triad. The previous bare `print(f"Bonsai: commit of {obj.name!r} via {finish_op} failed: {e}")` exception-handler is replaced with logger.warning(..., exc_info=True).

Numbered steps are -**required** unless flagged OPTIONAL. Keep this section in sync with the -implementation files it references — if a step's example code stops matching -the real registration site, the step is out of date. - -STEP 1 — Add the registry entry (this file) - Append to `Parametric.EDIT_TYPES`:: - - ParametricObject("slab", has_non_editable_path=False), - - The ``name`` token drives every derived identifier: - ``BIMSlabProperties``, ``bim.enable_editing_slab`` / - ``bim.finish_editing_slab`` / ``bim.cancel_editing_slab``, and the - ``slab`` field on ``GizmoPreferences``. Set ``has_non_editable_path=True`` - if the modifier exposes no user-editable path (cf. door, window, stair). - -STEP 2 — Define the ``PropertyGroup`` (``bim/module/model/prop.py``) - Class name **must** be ``BIMProperties`` — capitalisation matches - `ParametricObject.props_attr`:: - - class BIMSlabProperties(bpy.types.PropertyGroup): - is_editing: BoolProperty(...) - # ... per-type draft fields, snapshots, mesh_dirty, etc. ... - - The ``is_editing`` flag is the single field every consumer of the registry - expects. - -STEP 3 — Register the PropertyGroup class - Add it to the ``classes`` tuple in ``bim/module/model/__init__.py`` (near - the existing ``prop.BIMProperties`` entries). The - ``bpy.types.Object.BIMSlabProperties`` attachment is automatic — - `Parametric.register_object_properties` loops the registry. - -STEP 4 — Implement the Enable / Finish / Cancel triad - In ``bim/module/model/slab.py``, define three ``bpy.types.Operator`` - subclasses with the canonical ``bl_idname``\\s: - - - ``EnableEditingSlab`` → ``bl_idname = "bim.enable_editing_slab"`` - - ``FinishEditingSlab`` → ``bl_idname = "bim.finish_editing_slab"`` - - ``CancelEditingSlab`` → ``bl_idname = "bim.cancel_editing_slab"`` - - **First, check if your new type fits one of the existing lifecycle - shapes** in `bonsai.bim.parametric_lifecycle`. If it does, inherit - the matching mixin and the triad collapses to ~25 lines total: - - - ``FeatureModifierEditMixin`` — BBIM_ pset with nested - ``lining_properties`` / ``panel_properties``; Finish via - ``update__modifier_representation`` → - ``ifcopenshell.api.feature``; Cancel via - ``switch_representation`` to the Body rep. Reference samples: - door (multi-object) and window (single-object). - - - ``PathPreservingEditMixin`` — BBIM_ pset whose ``path_data`` - is preserved through edit; Finish via per-type - ``update_bbim__pset`` + ``update__modifier_ifc_data``; - Cancel rebuilds the bmesh preview. Reference samples: railing, roof. - - If neither shape fits (the type needs validation-first lifecycle, an - explicit snapshot, delegate-to-sub-operators Finish, or a unique - post-Finish step) implement the triad standalone — see ``wall.py`` - (validation/snapshot/delegate) or ``stair.py`` (raw pset JSON + - ``update_ifc_stair_props``) as references. Register all three in the - module's ``classes`` tuple. - -STEP 5 — Implement the gizmo group (same file) - Subclass ``BaseParametricGizmoGroup`` from - ``bim/module/drawing/gizmos.py``:: - - class GizmoSlabEdition(bpy.types.GizmoGroup, BaseParametricGizmoGroup): - bl_idname = "OBJECT_GGT_bim_slab_edition" - - @classmethod - def is_element_type(cls, element): - return tool.Blender.Modifier.is_slab(element) - - dimension_gizmo_props = [DimensionGizmoConfig(...)] - - Register it in the ``classes`` tuple. The classmethod makes - ``tool.Blender.Modifier.is_slab(element)`` testable via the gizmo's - ``poll()``. - -STEP 6 — Add the element-type predicate (``tool/blender.py``) - Inside the ``Blender.Modifier`` class, alongside ``is_door`` / ``is_wall``:: - - @classmethod - def is_slab(cls, element: entity_instance) -> bool: - return tool.Pset.get_element_pset(element, "BBIM_Slab") - - The method name **must** be ``is_`` to match - `ParametricObject.name` — `Parametric.find_for_element` - looks it up by string. - -STEP 7 — OPTIONAL: typed property accessor (``tool/model.py``) - Convenience helper for call sites that statically know the IFC type:: - - @classmethod - def get_slab_props(cls, obj) -> BIMSlabProperties: - return obj.BIMSlabProperties - - Call sites that work generically (registry-driven) can use - ``getattr(obj, feature.props_attr)`` directly and skip this step. - -STEP 8 — OPTIONAL: gizmo visibility preferences (``bim/ui.py``) - For per-gizmo show/hide toggles, define:: - - class GizmoPreferencesSlab(bpy.types.PropertyGroup): - length: BoolProperty(name="Length", default=True, ...) - # ... one BoolProperty per gizmo ... - - Then add a matching field on ``GizmoPreferences``:: - - slab: bpy.props.PointerProperty(type=GizmoPreferencesSlab) - - Do **not** add ``GizmoPreferencesSlab`` to the ``classes`` list in - ``bim/__init__.py`` — the registry-driven discovery in this module finds - it by name (``GizmoPreferences`` + capitalised registry token) and - registers it automatically. - -STEP 9 — OPTIONAL: pure geometry helpers (``core/model.py``) - Per-type math (collinearity checks, slope/displacement conversions, - intersection helpers) lives here.

All surface as addon-load / save-time exceptions on v0.8.0's bim layer because PR2's tool.Parametric refactor over-committed to the PR4 contract. 1. iter_gizmo_preference_classes — the previous implementation returned only the shared GizmoPreferencesFeature class. v0.8.0's bim/ui.py declares PointerProperty fields ('door', 'window', ...) on GizmoPreferences that point at per-feature GizmoPreferences classes; those must be registered BEFORE GizmoPreferences itself. The shared-class-only return broke addon registration with: 'door' PointerProperty could not register (see previous error) Restore the v0.8.0 per-feature lookup (iterate EDIT_TYPES, look up each GizmoPreferences on ui_module) and keep the shared-class lookup as forward-compat. Tag FIXME(PR5). 2. EDIT_TYPES — drop the array / pipe_segment / duct_segment entries from the registry. Their bim.finish_editing_ operators land with PR4. Registering them in PR2's EDIT_TYPES without the operators makes auto-commit-on-save dispatch a non-existent finish_op for any object whose BIMProperties.is_editing flag is True, raising: RuntimeError: 'bim.finish_editing_array' must be a registered tool.Ifc.Operator subclass for undo-safe IFC mutation PR4 re-adds the three entries together with their operators. Tag FIXME(PR4). 3. tool.Blender.Modifier shim block — upgrade the prose comment to a formal FIXME(PR5) marker so the PR5 cleanup sweep finds it via grep alongside every other tagged shim site.

Plus three type annotations that ty flagged as unresolved. 1. tool/system.py:get_decoration_data — drop the cache layer that keyed on a token from a bim/decorator_cache.py module. The cache is dead-or-broken in slim: the depsgraph bump handler that would invalidate the token lives in PR3's bim/handler.py decompose, so the token stays at 0 forever. Either the cache never hits (decorated_elements rebuilt → new id() per call) or returns stale data (list reused). Revert to direct `_build_decoration_data()` calls. PR3 reintroduces the cache atomically: decorator_cache module + handler install + cache wrap + tests. Keeps `_build_decoration_data` extraction (cleaner than v0.8.0's monolithic version regardless of cache). 2. tool/spatial.py — add `get_host_element` + `get_host_wall`. The interface stubs in `core/tool.py:1037-1038` were declared but never implemented. `tool/duplicate.py:99` (object duplication with fills) and `tool/model.py:1260` (array per-child opening mirror) call these and would raise AttributeError. 3. tool/model.py:recreate_wall — drop the fillet-corner branch that function-locally imports `regenerate_fillet_corner_wall` from `bim/module/model/wall`. The function lands with PR4; fall through to the straight-extrusion path preserves v0.8.0 behaviour for fillet walls until then. Tag FIXME(PR4). 4. tool/model.py — drop `get_pipe_segment_props` / `get_duct_segment_props` accessors. Their return types reference `BIMPipeSegmentProperties` / `BIMDuctSegmentProperties` which land with PR4's prop.py; calling either accessor on v0.8.0 would AttributeError on `obj.BIMSegmentProperties`. Zero callers in slim — PR4 reintroduces both accessors together with the PropertyGroups they wrap. Also drops the matching TYPE_CHECKING imports. 5. tool/blender.py:557 — `Mapping[type[ViewportDecorator], bool]` needs the qualified `Blender.ViewportDecorator` because the annotation is on a method INSIDE the same nested class; the bare name doesn't resolve at type-check time. 6. core/tool.py Surveyor — drop the `obj: "bpy.types.Object"` / `z: float` / `-> float` / `-> None` annotations on `get_z_rotation` / `set_z_rotation`. The `@interface` decorator wraps each method as `classmethod(abstractmethod(...))` at import time, but ty doesn't track the wrap and flags every call site as `missing-argument` plus the `pass` body as `empty-body` against the declared return type, plus the `bpy.types.Object` forward-ref as `unresolved-reference`. Reverting to v0.8.0's untyped style (matching the sibling `get_absolute_matrix(cls, obj)` stub) clears six ty errors at the cost of zero runtime semantics — the abstract stubs only serve as registry markers, concrete `tool.Surveyor.*` carries the real signatures.

Exports: * ``get_decorator_cache_token()`` — global int counter consumers include in their cache key so the value invalidates on structural scene changes. * ``_bump_decorator_cache_token()`` — ``@bpy.app.handlers.persistent`` callback that increments the token. Gates on the depsgraph payload so animation playback / driver evaluation doesn't churn the token. * ``install_decorator_cache_handlers`` / ``uninstall_…`` — idempotent append / remove against depsgraph_update_post + undo_post + redo_post + load_post. Called once from ``bim.register`` / ``unregister``. * ``TokenCache[T]`` — single-entry memoiser keyed on ``(caller_key, token)``. Cached ``bpy.types.Object`` references can't outlive the underlying ID blocks because any depsgraph / undo / load bumps the token and forces a recompute. This commit ships the module standalone. The next commits in this PR wire it: tool/system.py adds the cache wrap on get_decoration_data and bim/handler.py installs the bump callbacks.

Save-file invariants every load must re-establish (msgbus subscription, owner-settings, thumbnail cache, draft-flag healing, blend-warning flag, H5 lock probe). 2. User-preference-driven UI setup (toolbar, workspace, viewport shading, panel hijack, snap defaults). 3. Viewport overlay sync (every decorator's install/uninstall). Pull each into its own function (``_apply_save_file_invariants`` / ``_apply_user_preferences`` / ``_install_viewport_overlays``). The ``load_post`` callback becomes a 3-line orchestrator. Each phase is independently call-able from tests and from PR4 features that need to re-trigger one phase without the others. Two new hooks land with the decompose: * ``tool.Parametric.heal_stale_edit_flags()`` + ``discard_pending_previews(scene)`` fire in ``_apply_save_file_invariants``. The first clears object-level ``BIMProperties.is_editing`` flags that lost their backing IFC element across a load; the second clears scene-level ``BIMPreviewProperties..is_active`` so saved preview state never resurfaces with no UI to interact with it. * ``install_decorator_cache_handlers`` / ``uninstall_decorator_cache_handlers`` wrap the decorator install/install pass in ``_install_viewport_overlays``. The bump handlers append to ``depsgraph_update_post`` + ``undo_post`` + ``redo_post`` + ``load_post`` so the previous commit's ``TokenCache`` in ``tool.System.get_decoration_data`` finally invalidates on structural scene changes.

Always-on drift triad on ParametricEditMixinBase. The base now provides ``_handle_drift_on_enable`` / ``_handle_drift_on_finish`` / ``_handle_drift_on_cancel`` classmethods, called from the per-mixin ``_enable_one`` / ``_finish_one`` / ``_cancel_one``. Pre-edit Blender-side translations commit to IFC on Enable (apply_scale=False — only translation/rotation, not the user's accidental scale), in-edit drag commits on Finish (apply_scale=True), and Cancel restores the committed IFC placement via ``restore_or_rebaseline_placement``. Prevents the "uncommitted drag disappears on Finish" and "preview snaps back on Cancel" UX bugs. 2. ``_ParametricEditMixinBase`` renamed to ``ParametricEditMixinBase`` (public). Per-feature mixins that need to subclass directly (e.g., when neither FeatureModifier nor PathPreserving fits) can do so without reaching into a private name. 3. ``_update_modifier_bmesh`` (PathPreserving) renamed to ``_restore_viewport_after_cancel``. The old name was inaccurate for subclasses that load a different IFC representation on Cancel rather than rebuilding a bmesh preview from props. Plus two polish changes: * ``_mark_type_thumbnail_dirty`` helper on the base centralises the ``ifcopenshell.util.element.get_type`` + thumbnail-mark pattern that both mixins repeated inline. * ``FeatureModifierEditMixin._cancel_one`` and ``PathPreservingEditMixin._cancel_one`` wrap the restore in ``try/finally`` so ``props.is_editing = False`` flips even on partial restore failure. Without this, a Cancel that raised mid-restore would leave the user locked out of the edit lifecycle. * ``PathPreservingEditMixin._finish_one`` / ``_cancel_one`` skip the pset commit + viewport rebuild when the draft equals the stored pset (no-op Enable→Finish round-trip should not pollute the representation list or burn an undo entry). ``FeatureModifierEditMixin._finish_one`` now routes the pset commit through ``tool.Pset.write_bbim_data`` instead of inlining the ``createIfcText(json.dumps(...))`` + ``ifcopenshell.api.pset.edit_pset`` dance. Two test assertions updated to match.

Add a registry of per-type regenerator functions (``UNDO_REGENERATORS``) that re-build each type's preview mesh from its current props. The dispatcher ``resync_parametric_drafts_after_undo`` walks all objects, skips any without an active parametric edit, looks up the regenerator by feature name, and calls it. Tagged 3D viewports for redraw. Types without an entry (door / window / railing / etc.) are intentionally absent — they're IFC-derived, so the undo's representation rollback + next-frame refresh already repaints correctly without a draft-side regenerator. Undo/redo wiring is self-installed by ``bonsai.bim.parametric_lifecycle``: a ``@persistent`` ``_resync_on_undo`` callback dispatches into the registry, and ``install_parametric_lifecycle_handlers()`` / ``uninstall_parametric_lifecycle_handlers()`` append/remove it from ``bpy.app.handlers.undo_post`` and ``redo_post``. ``bim/__init__.py``'s ``register()`` calls the install function *after* the central ``handler.undo_post`` / ``redo_post`` appends so the regenerators see restored IFC state — ``bpy.app.handlers`` fire in append order. ``handler.py`` itself stays ignorant of the parametric subsystem. The lazy function-local imports in each regenerator break the addon-load cycle — ``bonsai.bim.parametric_lifecycle`` loads before ``bim/module/model/*``.

Transferring via RelatingOpeningElement keeps the rel pointing at the new opening so the door stays associated. Pre-existing bug from 5a6476a57, surfaced by ef144dce2.

The daily build's linux-wheel safeguard fires when the resulting cachebox-*-manylinux_*.whl leaks into the macOS / windows wheels folder (builds run on ubuntu-latest and cross-build via pip download --platform). Pin deepdiff to <9.1 (resolves to 9.0.0, no cachebox transitive dep) as the minimal hotfix.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three operator mixins for type-selection ops on parametric features (door type-cycle, window type-pick, stair type-cycle, railing type-pick, roof type-cycle, etc.). Each shares the same contract: * ``element_checker`` validates the active object is the expected IFC type * ``props_getter`` resolves the BIMProperties group * ``type_literal`` is the Literal type whose args drive the enum * ``type_attr`` is the PropertyGroup field to read/write * ``skip_element_check=True`` bypasses element validation (for operators that target a non-IFC context) CycleTypeMixin shift-click reverses direction (forward by default). PickTypeMixin opens a popup menu and routes the picked value through execute() so F6 redo / EXEC_DEFAULT reach the apply path. The PickType modal-handler dance waits for LEFTMOUSE release before opening the menu when invoked mid-click (e.g. from a gizmo's target_set_operator) so Blender's drag-through-pick gesture doesn't commit an accidental item. Ships standalone — the next commit's gizmos.py framework refactor re-exports these names from bonsai.bim.parametric_lifecycle so gizmo modules can spell ``gizmo.CycleTypeMixin`` / ``gizmo.PickTypeMixin``. Concrete operator subclasses land in subsequent PR4 commits per feature (door / window / stair / railing / roof).

Framework primitives — StaticTrisGizmoMixin + TexturedQuadGizmoMixin replace the older TrisGizmoMixin. New module-level helpers: _get_static_tris_shader / _get_static_tris_batch / clear_static_ tris_cache for cached GPU batch reuse, _draw_outline_and_body for the shared outline-then-body render path, draw_tris_with_outline as the public wrapper. billboarded_at(world_pos, billboard_rot, scale) is the canonical billboard-matrix helper; should_flip_extend_ arrow encapsulates the view-aware mirror decision for extend gizmos; get_warning_color_from_prefs reads the user's warning color. 2. Config classes — BaseValueGizmoConfig (shared visibility + dimension- text contract), CountGizmoConfig (array N indicator), DimensionGizmoConfig (length / height / depth labels), IconActionConfig (icon-only gizmos that invoke an operator on click). DimensionRenderer draws the actual numeric label using BLF. 3. Icon classes — each rewritten on StaticTrisGizmoMixin so they share the cached GPU batch + outline-then-body render path: GizmoLockOpen / GizmoLockClosed (replacing the single-state GizmoLock), GizmoArc, GizmoFillet, GizmoWallCornerIcon, GizmoWallTeeIcon, GizmoPen / GizmoValidate / GizmoCancel (the parametric-edit triad), GizmoPlus / GizmoMinus / GizmoTrash, GizmoArrayParent / GizmoArrayAll / GizmoArrayLayerIndicator (array context indicators with a small digit-rendering helper for the "xN" count label), GizmoMerge / GizmoSplit / GizmoUnjoin (wall-join icons), and GizmoMenu (textured-quad icon-action menu trigger). The legacy TrisGizmoMixin, GizmoLock, and DimensionDrawConfig are removed; downstream callers in subsequent PR4 commits swap to the new mixin and config classes when their feature operators land. CycleTypeMixin / PickTypeMixin / TypeAccessorBase live in bim.parametric_lifecycle (previous commit). The three mixins are re-exported from gizmos.py here so feature-module access via ``gizmo.`` keeps working until PR5 cleanup drops the re-exports. bim/module/drawing/__init__.py is updated in the same commit to register the 11 new gizmo classes (GizmoLockOpen / GizmoLockClosed / GizmoFillet / GizmoWallCornerIcon / GizmoWallTeeIcon / GizmoTrash / GizmoArrayParent / GizmoArrayAll / GizmoArrayLayerIndicator / GizmoUnjoin / GizmoMenu) — without that, the new classes exist in gizmos.py but aren't usable as bpy gizmo types.

Register / annotation resolution * parametric_lifecycle.py: hoist `entity_instance` import out of TYPE_CHECKING so typing.get_type_hints resolves the Callable[[entity_instance], bool] annotation at operator registration (CycleDoorType, CycleWindowType, CycleStairType failed with NameError). Clarify the INTERFACE return contract on the picker entry-point so readers see why the gizmo step stays off the undo stack. Framework callable contracts * model/wall.py, door.py, window.py, stair.py: migrate `props_getter` and `element_checker` from bl_idname strings to bound classmethods on tool.Model / tool.Parametric. BaseParametricGizmoGroup.get_props expects a callable; the string form raised TypeError on first gizmo poll. * model/door.py, model/stair.py: drop the dead `prop_path=` operator kwarg from create_arc_gizmo / create_icon_gizmo call sites. The framework helper blindly setattrs every kwarg onto the operator's OperatorProperties, but ToggleDoorSwing / ToggleStairProperty don't declare prop_path — the setattr raised mid-setup_element_specific_gizmos, so self.gizmo_door_type / self.lock_gizmo never got assigned and every subsequent draw_prepare tornadoed AttributeError. Nothing reads op.prop_path anywhere; the kwarg was dead data. Dispatcher operators * model/array.py: add EnableEditingParametric (the framework pen-icon dispatcher that routes to a per-feature edit operator by bl_idname string) and AddArrayFromFeatureEdit (binds the framework's array icon to bim.add_array on the current parametric draft). * model/__init__.py: register both new operators. Per-frame robustness * drawing/gizmos.py: guard BaseParametricGizmoGroup.draw_prepare with is_setup_complete() — matches the existing guard in refresh() and in BaseSchematicGizmoGroup.draw_prepare(). Defense-in-depth: when any subclass's setup raises mid-way, draw_prepare now no-ops cleanly instead of per-frame AttributeError-tornadoing on whatever attribute the failed setup phase was meant to populate. * model/decorator.py: guard ProfileDecorator.__call__ against context.active_object is None. The decorator is a per-frame viewport draw handler; deselecting or deleting the active object while it's installed crashed on obj.mode access. Treat None the same as "no longer in edit mode" — uninstall + fire the exit callback if present. * geometry/data.py: ViewportData.load() populates `data` before flipping `is_loaded`, so a raise from cls.mode() no longer leaves the class flag-set but data-empty for subsequent reads.

Users select two LAYER2 walls, click the fillet entry icon, drag the live radius widget, and validate to replace the corner with a curved LAYER2 corner wall (banana body). Operators (5): * EnableWallFilletPreview: 2-wall selection → validates LAYER2 + straight axis + zero-slope + intersect-or-joined state → seeds the preview props with a default radius computed from the shorter available leg. * FinishWallFilletPreview: dispatches CreateWallFillet with the tuned radius; clears preview state on FINISHED, preserves it on failure so the user can re-tune without re-selecting. * CancelWallFilletPreview: clears preview state, no IFC mutation. * EnableWallFilletPreviewFromCorner: pen-icon re-edit on an existing fillet corner — pre-fills the preview from the corner's BBIM_Wall pset + walks the inverse graph to recover wall A and wall B. * CreateWallFillet: deletes any prior corner + A↔B path connection, shortens A and B to the tangent points, instantiates a corner wall from A's type, unassigns the swept-layer material/type (the explicit banana body MUST own its geometry), assigns the dominant material, rebuilds the body, sets a straight 2-point chord axis, stores BBIM_Wall.IsFilletCorner+FilletRadius, reconnects A and B to the corner with NOTDEFINED on the corner's side. Gizmo groups (2 new + entry icon on existing): * GizmoWallFilletPreview: visible while a preview is active. Bundles a radius_dim widget at the arc apex, a trim_dim widget along wall A expressing the same DOF via the leg setback distance (trim = |radius| * tan(sweep/2)), and validate / cancel icons anchored above the apex in screen-up. * GizmoWallFilletReedit: pen-icon entry on an existing fillet corner wall (single-selection, BBIM_Wall.IsFilletCorner set, both neighbour connections present). Mutually exclusive with an active preview. * GizmoWallJoinIntersection now stacks a fillet entry icon (VIEW3D_GT_fillet → bim.enable_wall_fillet_preview) above the existing join/unjoin icon in the joined and intersect state branches. Property + decorator infrastructure: * prop.py: BIMWallFilletPreviewProperties (Scene-level draft) + BIMPreviewProperties umbrella with only the wall_fillet pointer. The umbrella is the seam preview_base.py (landed in PR3) already reads via getattr(scene, "BIMPreviewProperties", None). * decorator.py: _stroke_lines_alpha helper + WallFilletPreviewDecorator. Polls is_active; renders leg projections + arc + arc-center construction lines from tool.Wall.compute_wall_fillet_geometry. * __init__.py: registers operators + gizmo groups + property groups + wires Scene.BIMPreviewProperties. * handler.py: WallFilletPreviewDecorator.install/uninstall in _install_decorators — always installed, self-polls on is_active. Drive-by: extract gizmo.get_screen_up(billboard_rot) helper — the local +Y of a billboard rotation is the camera's screen-up world direction. Replaces 4 inline `billboard_rot @ Vector((0.0, 1.0, 0.0))` sites added across the fillet feature's gizmo groups.

Sister gizmos competed with the active preview: * preview_base.any_preview_active(context): new helper iterates the PREVIEW_CANCEL_OPS registry and returns True if any preview is open. Future previews registered there automatically gate sister gizmos. * BaseParametricGizmoGroup.poll (gizmos.py): short-circuits on any_preview_active so every parametric gizmo (door/window/stair/ roof/railing/wall edition) hides during ANY preview. * The 4 wall gizmo groups with explicit polls (GizmoWallAddOpening, GizmoWallExtendVertically, GizmoWallJoinIntersection, GizmoWallUnjoinSingle) + GizmoWallFilletReedit gain the same gate. DRY: extract _wall_gizmo_poll_gate(context): * 5 wall gizmo polls each duplicated the 2 pre-flight checks (viewport-gizmos enabled + no preview active). The helper centralises them — each poll becomes a single short-circuit line followed by its per-feature selection inspection. ESC cancels the active preview: * try_cancel_active_preview already existed in preview_base since PR3 but had no caller. Hooked into OverrideEscape.execute (geometry/ operator.py) as a new elif branch — same keymap that already cancels pen gizmo edit mode + item mode + edit mode + aggregate mode. Order in the branch chain matters: try preview cancel before falling back to try_canceling_editing_modifier_parameters_or_path so the in- flight preview wins over a stale modifier-edit cancel attempt.

A. Migrate wall.py to PR3-absorbed tool methods (fixes bug 4: pen icon missing on fillet corner walls): PR3 shipped tool.Wall.read_geometry + tool.Wall.validate_for_parametric_edit but wall.py kept local duplicates predating that work. The local _read_wall_geometry guards on tool.Blender.Modifier.is_wall (LAYER2-only) while the tool method guards on tool.Parametric.is_path_connectable_wall (LAYER2 OR fillet corner). Consequence: _get_wall_geom_cached → local _read_wall_geometry returned None for every fillet corner → GizmoWallFilletReedit.position_gizmos hit `if geom is None: hide` → pen icon was unreachable for every fillet corner the user created. Three _read_wall_geometry callers migrated to tool.Wall.read_geometry (_read_wall_state_into_props, _get_wall_geom_cached, GizmoWallJoinIntersection.position_gizmos). Two _validate_wall_for_parametric_edit callers migrated to tool.Wall.validate_for_parametric_edit (_maybe_resync_wall_props_from_ifc, EnableEditingWall._execute). Local helpers deleted; docstring references updated. B. Drop over-restrictive gizmo gates (fixes bug 1: join icons missing when walls intersect away from endpoints): GizmoWallJoinIntersection.position_gizmos no longer hides itself when the projected intersection lands further than MAX_DISTANCE_TO_ENDPOINT_ FACTOR (0.75 wall lengths) from any endpoint. The remaining PARALLEL_DOT_THRESHOLD (cos 2°) gate via project_axis_intersection returns None for near-parallel walls and is the only correctness bound; distance from endpoints is a UI concern, not a geometric one. GizmoWallFilletReedit.poll drops the has_a / has_b ConnectedFrom + ConnectedTo guard — the IsFilletCorner pset is the authoritative signal. EnableWallFilletPreviewFromCorner.execute already separately validates both neighbour connections and reports a user-facing error if either side is disconnected.

Every test walks the live registry or class hierarchy instead of hard-coding preview keys, operator names, or helper function names, so adding a new preview / wall gizmo group / fillet operator exercises the same invariants without test edits. test_preview_base.py (6 tests): * RegistryContract: every PREVIEW_CANCEL_OPS entry resolves to a callable cancel operator on bpy.ops.bim. * GetPreviewPropsTolerance: get_preview_props returns None for contexts without a scene (regression guard for the SimpleNamespace bug fixed in commit ee63137c6). * ActivationCycle (registry-driven loop): any_preview_active toggles with each registered preview's is_active flag; discard_pending_previews clears every active flag across every registered preview. * SaveOnDiscardWired: locates the bim.save_project operator dynamically and verifies its execute path references the discard helper by its actual __name__. test_wall_gizmo_poll_gate.py (4 tests): * WallGizmoGroupsHideDuringPreview: walks the wall module for bpy.types.GizmoGroup subclasses (skips preview-owner exceptions whose bl_idname contains 'preview'), mocks any_preview_active to True, and asserts every discovered gizmo's poll returns False. * BaseParametricGizmoPollHidesDuringPreview: mirrors the test for the cross-feature parametric framework base class. test_fillet_operators.py (3 tests): * FilletOperatorsRegistered: at-least-four-ops + every-discovered-op- is-callable. Catches accidental deregistration. * EnableRejectsIneligibleSelection: poll returns False without a selection so the operator is greyed-out in menus. State-clearing tests via bpy.ops.bim.cancel_wall_fillet_preview() are deliberately omitted — the operator early-returns when context.screen is unattached and prior tests in the model lane can leave the screen in that state, making the dispatch path inherently flaky.

Restores the array_gizmo icon's positioning + visibility in the framework's parametric edit row. Registry (tool/parametric.py): * EDIT_TYPES adds ParametricObject("array", supports_build_edit_lifecycle=True). _ArrayEditMixin in array.py feeds build_edit_lifecycle which auto- generates EnableEditingArray / FinishEditingArray / CancelEditingArray with the conventional bl_idnames the gizmo references. tool/blender.py: * Adds is_array predicate wrapper around tool.Parametric.is_array. The registry contract test test_every_entry_has_modifier_predicate enforces every EDIT_TYPES entry has a matching is_ wrapper on tool.Blender.Modifier. array.py (+1130 LOC port from gizmos-8088): * _ArrayEditMixin(ParametricEditMixinBase) drives the auto-generated enable / finish / cancel lifecycle. * GizmoArrayEdition: validate + cancel + count display + +/- adjusters + method toggle + delete button + per-layer ARRAY entry icons (preallocated pool of MAX_LAYER_GIZMOS=8). * GizmoArrayChild: child-array gizmo for the array-replica case. * EditArrayFromChild: resolves the spawning layer via tool.Array.get_child_layer_index so clicking a child's array gizmo opens the layer that produced that child rather than always layer 0 (the gizmos-8088 source itself hardcoded item=0; HEAD has the helper to do it right). * New operators: EnableEditingArrayItem, ArrayParentGizmoClick, ArrayGizmoClick, ToggleArrayMethod, RemoveArrayLayerFromEdit, InputArrayCount, AdjustArrayCount. prop.py: BIMArrayProperties gets per_child_opening BoolProperty (when the array parent fills a host, give each child its own opening + filling pair). Bug fix: guard update_relating_array_from_object against the cleanup-time None set. _finish_one writes relating_array_object = None to clear the source-array reference; that fired the update callback, which dispatched bpy.ops.bim.enable_editing_array(item=self.is_editing). With is_editing just flipped to False, the bool coerced to 0 and re-opened layer-0 edit immediately after every validate. The guard short-circuits on None; item is also fixed to 0 (the bool-as-layer- index was always meaningless for the legitimate user-pick path). decorator.py (+312 LOC, all ports from gizmos-8088): * bbox_world_edges / draw_polyline_segments / _BBOX_EDGES - shared geometry helpers usable across array decorators. * draw_array_layer_children_bbox - green wireframe bbox per child of one array layer, drawn inline from a gizmo's draw() so the highlight tracks the hover cursor without POST_VIEW lag. * ArrayPreviewDecorator - faint cyan ghost bboxes at each future array instance during the edit lifecycle (offset math mirrors Model.regenerate_array, gated on props.is_editing). * ArraySelectionHighlightDecorator - bounding-box overlay surfacing the array family of the selected object. Child selected -> parent in special color + siblings in unselected color; parent selected (idle) -> all children in unselected color. TokenCache-backed. handler.py: imports + uninstall/install the 2 always-on decorators in _install_viewport_overlays. Both self-poll, so installation has no cost when no array is selected / in edit mode. Registration (bim/module/model/__init__.py): * Adds the 3 lifecycle classes generated by build_edit_lifecycle (CancelEditingArray, EnableEditingArray, FinishEditingArray) - they exist as module-level names but are only visible to Blender's operator registry when included in the classes tuple. * Adds the 8 new operators + 2 new gizmo groups in alphabetical order. gizmos.py: restores the array_gizmo icon position + visibility block in BaseParametricGizmoGroup.update_editing_gizmos. Was force-hidden in c250b2c1a because no array gizmo existed; the icon's plumbing comes back online now that GizmoArrayEdition is registered. Verified by test/bim/test_parametric_registry.py: all 8 tests pass - enable/finish/cancel ops resolve, PropertyGroup attached, is_array predicate present, predicate is total on non-matching elements.

The partner filter inside _iter_path_connections used the stricter tool.Blender.Modifier.is_wall (LAYER2-only), so adjacent LAYER2 walls silently dropped their fillet-corner partners from the connection list — the unjoin icon appeared when the fillet wall itself was selected but not on either of its LAYER2 neighbours.

Cause: _apply_fillet_corner_geometry derived the corner's local X axis from `chord = tangent_b - tangent_a` (a 3D vector). With walls at different Z, `chord.z` was non-zero, so `x_dir = chord.normalized()` inherited that Z component. The Z axis was already hardcoded to world Z, so x_dir and z_dir were no longer orthogonal — the resulting matrix_world was non-orthonormal, and Blender's Euler decomposition surfaced the skew as the visible X/Y rotation drift. Project the chord to the XY plane before normalising so x_dir is strictly XY-aligned and orthogonal to z_dir. The corner wall is now placed at wall A's elevation with a pure Z rotation, which matches the user's expectation when both inputs are Z-aligned regardless of their relative elevation.

Add GizmoLinkToggle (VIEW3D_GT_link_toggle): two filled dots joined by a horizontal connector in the default state. On hover the two halves shear vertically apart — left dot+stub slip down as a unit, right dot+stub slip up — with a horizontal gap at the centre, signalling that a click will sever the underlying connection. The glyph lives next to the generic icon classes (GizmoLockOpen/Closed, GizmoArc) so any path / link / pair-of-connected-items context can reuse it; it isn't wall-specific despite the first caller. The class keeps its own per-state GPUBatch cache so the shape swap on hover doesn't allocate per frame. The hit-shape is sourced from the broken form (the larger bbox of the two states) so the cursor doesn't lose hover at the offset dots' outer edges and flicker between states. GizmoWallUnjoinSingle.setup() now requests VIEW3D_GT_link_toggle. The operator binding (bim.unjoin_wall_path_connection), the POOL_SIZE, and the per-frame partner-GUID write are unchanged.

Forgetting the bump silently collided icons — wall's rotate icon and the array button both landed at X=1.24 in edit mode. The new IconSlot dataclass + feature_slots tuple replace the constants-and-override pattern with order-driven positioning: the layout manager assigns each slot an X from its tuple index plus a uniform ICON_ARRAY_GAP. Adding an icon is now a one-line append; the "forget to bump" failure mode is structurally impossible. Slot capabilities cover every existing icon-row shape: * Single icon (wall rotate, array delete). * N-variant slots — N gizmos at the same X with one visible per frame via a subclass picker (stair tread-lock open/closed, wall baseline exterior/center/interior). Pair becomes the N=2 case; triplet the N=3 case. Variant idnames can be authored either as a tuple of explicit names or as a string prefix that auto-suffixes _. * Visibility prefs gate slot rendering without reflowing the row — hidden slots still consume their X position. * Extra per-slot gap before for visual separation (array's delete trails the routine controls by an extra 0.2 m). * Operator props forwarded to target_set_operator so adjusters (+/-, increment) and generic toggles (property_name=...) work. When the cycle slot is unused, feature slots collapse into the cycle position so the row stays tight — that's how wall's baseline triplet sits at X=0.87 without a gap before it. Three subclasses migrate to the new system: * wall.py — rotate icon + baseline triplet variants. Drops ICON_ROTATE_X, _BASELINE_GIZMO_ATTRS, the manual triplet creation loop, and the matching positioning block in _update_icon_row_extras (it now just picks variant visibility). * stair.py — tread_lock pair (open/closed) + plus + minus. _update_editing_icon_positions reads slot X via _slot_x_positions instead of three hardcoded constants. Also fixes the standalone total_length_lock gizmo, which was broken since PR4 split VIEW3D_GT_lock into open/closed pair (caller wasn't updated). * array.py — count_minus + count_plus + method + delete (with extra_gap_before=0.20 to separate the destructive action). Drops the manual edit-row positioning loop entirely; the base loop handles it. GizmoArrayChild now inherits BillboardingGizmoGroupMixin and uses the shared setup_icon_gizmo helper, dropping its duplicated _make_icon wrapper. Two helpers added on BillboardingGizmoGroupMixin to fold the duplicated prefs/color preamble that appeared at the top of six wall gizmo setups plus the array-child setup: * get_decoration_colors() — (decorations_colour, decorator_color_selected), the active-state pair. * get_unselected_decoration_colors() — (decorator_color_unselected, decorator_color_selected) for gizmos surfaced on already-selected geometry that should not pull focus.

charset=UTF-8 Content-Transfer-Encoding: 8bit Hovering a wall-junction link-toggle icon today only swaps the icon shape — the user doesn't see which wall the click will disconnect from until after they click. ATPATH (T-junction) configurations especially make the partner ambiguous when multiple connections sit close together. On hover, paint a wireframe bbox around the partner wall using the same shader, constants and color the array module already established for its layer-children highlight (POLYLINE_UNIFORM_COLOR, decorator_color_special, line width 1.8, alpha 0.8). The line-width / alpha constants in decorator.py are renamed from _ARRAY_LAYER_BBOX_LINE_* to _BBOX_HIGHLIGHT_LINE_* and shared between draw_array_layer_children_bbox and the new draw_wall_partner_bbox so the two highlights stay in lockstep. The trigger lives in a new GizmoWallLinkToggle subclass in wall.py which keeps the base gizmos.GizmoLinkToggle generic (per the generic-naming convention for shared widgets). The subclass's draw() calls super().draw(context) then on self.is_highlight outlines its partner_obj via the shared decorator helper. Same trigger pattern as GizmoArrayLayerIndicator. Blender's Gizmo API exposes target_set_operator but no symmetric getter, so the partner reference can't be read back from the bound operator handle. Instead GizmoWallUnjoinSingle.position_gizmos mirrors the resolved partner_obj onto each visible icon every frame next to the existing other_wall_guid write — the icon's draw() reads from its own __slots__-declared attribute. A forward-compat AST test pins the contract: GizmoWallLinkToggle.draw must reference is_highlight and call draw_wall_partner_bbox. Catches the regression where someone tidies the draw() override into super() or replaces the shared helper with an ad-hoc draw call. Generated with the assistance of an AI coding tool. --- .../bonsai/bim/module/model/__init__.py | 1 + .../bonsai/bim/module/model/decorator.py | 31 ++++++++++++++-- src/bonsai/bonsai/bim/module/model/wall.py | 37 ++++++++++++++++++- .../model/test_wall_gizmos_forward_compat.py | 31 ++++++++++++++++ 4 files changed, 95 insertions(+), 5 deletions(-) diff --git a/src/bonsai/bonsai/bim/module/model/__init__.py b/src/bonsai/bonsai/bim/module/model/__init__.py index c60048a5db..9085e72ae7 100644 --- a/src/bonsai/bonsai/bim/module/model/__init__.py +++ b/src/bonsai/bonsai/bim/module/model/__init__.py @@ -108,6 +108,7 @@ classes = ( wall.GizmoWallFilletPreview, wall.GizmoWallFilletReedit, wall.GizmoWallJoinIntersection, + wall.GizmoWallLinkToggle, wall.GizmoWallUnjoinSingle, wall.JoinWallsIntersection, wall.MergeWall, diff --git a/src/bonsai/bonsai/bim/module/model/decorator.py b/src/bonsai/bonsai/bim/module/model/decorator.py index f45cd9b135..18c07ea57c 100644 --- a/src/bonsai/bonsai/bim/module/model/decorator.py +++ b/src/bonsai/bonsai/bim/module/model/decorator.py @@ -2233,8 +2233,8 @@ def draw_polyline_segments( gpu.state.blend_set("NONE") -_ARRAY_LAYER_BBOX_LINE_WIDTH = 1.8 -_ARRAY_LAYER_BBOX_LINE_ALPHA = 0.8 +_BBOX_HIGHLIGHT_LINE_WIDTH = 1.8 +_BBOX_HIGHLIGHT_LINE_ALPHA = 0.8 _ARRAY_LAYER_BBOX_MAX_CHILDREN = 200 @@ -2283,8 +2283,31 @@ def draw_array_layer_children_bbox( context, segments, color, - _ARRAY_LAYER_BBOX_LINE_ALPHA, - _ARRAY_LAYER_BBOX_LINE_WIDTH, + _BBOX_HIGHLIGHT_LINE_ALPHA, + _BBOX_HIGHLIGHT_LINE_WIDTH, + ) + + +def draw_wall_partner_bbox( + context: bpy.types.Context, + partner_obj: bpy.types.Object, +) -> None: + """Paint a wireframe bbox around ``partner_obj`` in the same 3D pass. + Called inline from gizmo ``draw()`` methods so the highlight tracks the + hover cursor one-for-one — no POST_VIEW handler, no timing lag. + + Silently no-ops if the object has no bounding box (e.g. Empties).""" + segments = bbox_world_edges(partner_obj) + if not segments: + return + prefs = tool.Blender.get_addon_preferences() + color = prefs.decorator_color_special[:3] + draw_polyline_segments( + context, + segments, + color, + _BBOX_HIGHLIGHT_LINE_ALPHA, + _BBOX_HIGHLIGHT_LINE_WIDTH, ) diff --git a/src/bonsai/bonsai/bim/module/model/wall.py b/src/bonsai/bonsai/bim/module/model/wall.py index 016e36ddcd..ea1f938d0d 100644 --- a/src/bonsai/bonsai/bim/module/model/wall.py +++ b/src/bonsai/bonsai/bim/module/model/wall.py @@ -3546,6 +3546,36 @@ class GizmoWallJoinIntersection(bpy.types.GizmoGroup, _WallGeomCachedBillboardin self.merge_icon.hide = True +class GizmoWallLinkToggle(gizmo.GizmoLinkToggle, bpy.types.Gizmo): + """Link-toggle glyph with a partner-wall highlight on hover.

Without it, walls regenerated from the parametric edit draft could ship with inward-facing normals on some faces, which rendered as visual holes under any backface-cull or normal-aware shading. ``test/bim/module/model/test_wall_preview_mesh.py`` pins the invariant (every face's normal points away from the wall centre). * **Color constants DRY.** ``COLOR_RED`` / ``COLOR_GREEN`` / ``COLOR_BLUE`` / ``COLOR_NEUTRAL`` now live at module scope in gizmos.py; the BaseParametricGizmoGroup class attributes alias the same tuples so ``self.COLOR_GREEN`` keeps working. IconSlot declarations in stair.py (plus / minus) and array.py (count_minus / count_plus / delete) now reference the named constants instead of duplicating the RGB tuples inline.

Text-only — no 2x2 grid glyph. Structural changes that enable this cleanly: * IconSlot.placeholder=True: slots reserve an X position in the row without auto-creating a gizmo. Subclasses resolve the reserved X via _slot_x_positions()[name] to place their own dynamic gizmos. Drops the brittle "remember to add extra_gap_before" workaround that would silently rot on slot reorders. * Array bug fix: the count badge collided with the "-" icon because the slot manager placed count_minus at the cycle position (X=0.87) where ICON_NUMBER_X also lives. Migrating the badge to a placeholder slot lets the manager allocate the X naturally and the "-" no longer overlaps. ICON_NUMBER_X constant removed. * IntegerInputDialogMixin in parametric_lifecycle.py: extracts the popup-dialog plumbing shared between InputArrayCount and the new InputStairTreads. Subclasses declare an IntProperty + attr_name + props_getter; the mixin owns invoke/execute. _resolve_props helper factors the common obj/props/requires_editing prologue. Tests: BIM_GT_count_label registration; IconSlot placeholder contract (no gizmo_idname required; gizmo_attrs() returns empty); the stair edit-row slot layout reserves the label position between tread_lock and plus at one ICON_ARRAY_GAP each; visibility propagates from props.is_editing.

SINGLE_SWING_RIGHT also lacked an X-mirror on the primary arc, so the swing extended past the door's right edge instead of sweeping back over the panel. Five related fixes / additions: * Drop the leftover ``prefs.decorations_colour[:3]`` per-frame colour override (the setup-time ``decorator_color_special`` is the durable contract — there's no reason to overwrite it every refresh). * Add X-mirror to RIGHT-hinged single-panel transforms so the arc sweeps back over the door rather than past the right edge. * Treat DOUBLE_DOOR_SINGLE_SWING as a two-panel layout: 4 arcs total (left + right panels, each with its own Y-mirrored flip) scaled to ``overall_width / 2``. * Hide all swing arcs for SLIDING_TO_LEFT / SLIDING_TO_RIGHT / DOUBLE_DOOR_SLIDING — sliding doors don't swing. A slide-direction indicator is deferred to a separate change. * Pin ``select_bias = -1000.0`` on every arc gizmo so the big quarter-arc hit shapes don't steal clicks from the smaller dimension and edit gizmos drawn on top. Architectural cleanup driven by the same diff: the imperative 4-create + 50-line update block is replaced by a declarative ``swing_arc_props`` list of ``SwingArcConfig`` entries (mirrors the existing ``dimension_gizmo_props`` pattern). Setup iterates the list and creates one (main, flip) pair per entry under ``gizmo_swing_arc_`` / ``gizmo_swing_arc__flip``; update iterates the same list and positions each pair via the lambdas. Adding a hypothetical multi-panel variant becomes a config entry rather than two more attribute names plus a transform branch. ``ToggleDoorSwing`` gets a ``description`` classmethod that returns user-facing wording per ``flip_geometry`` branch so the tooltip on hover stops reading like operator internals. ``test/bim/module/model/test_door_gizmos.py`` (new) pins the per-door-type contract: 11 cases covering LEFT / RIGHT hinge positions, DOUBLE_SWING parity with SINGLE_SWING, DOUBLE_DOOR 4-arc layout, the sliding-types hide invariant, ``is_editing=False`` hide invariant, flip-arc matrix re-assignment, and world-matrix pre-multiplication.

The "is this layer in edit mode" predicate compared a BoolProperty against an int (props.is_editing == i). Python evaluates False == 0 as True, so layer 0 always rendered the per-layer edit form even when no edit was active — clicking validate/cancel then dispatched against a phantom edit state. Switched to props.editing_item_index == i, which defaults to -1 and matches exactly one layer when an edit is active. 2. The panel's CHECKMARK and CANCEL buttons called bim.edit_array / bim.disable_editing_array, a parallel lifecycle that only cleared editing_item_index. Entering edit mode via the viewport gizmo (bim.enable_editing_array, the triad enter) sets is_editing=True and hides array children; the legacy panel exit unwound neither — so committing or cancelling from the panel left is_editing=True with children hidden, and the viewport gizmo thought the edit was still in progress. Re-bound both panel buttons to the canonical triad operators (bim.finish_editing_array / bim.cancel_editing_array), which _ArrayEditMixin already owns and which the viewport gizmo group already uses. Panel and gizmo now share one exit path. The three now-unreachable operators are deleted with their registration entries: EditArray (bim.edit_array), DisableEditingArray (bim.disable_editing_array), and EnableEditingArrayItem (bim.enable_editing_array_item, never called from any UI). The two test/tool/test_model.py sites that drove bim.edit_array as a commit step are switched to bim.finish_editing_array. External scripts or user keymaps bound to bim.edit_array / bim.disable_editing_array will need to update — the replacements are bim.finish_editing_array and bim.cancel_editing_array, both taking no parameters (the layer is read from props.editing_item_index).

The function does two things — refresh read-only header values (extrusion_depth/length/x_angle) and re-target user-intent enums (ifc_class, relating_type_id) from the active object. Doing both on the commit path crashed on IfcAnnotation actives (the type isn't in the bim_tool ifc_class enum) and silently overwrote the user's "what to build next" choice on every other element. Split the function: update_bim_tool_props remains selection-driven and does both halves; new refresh_bim_tool_headers is header-only and is what refresh_post_commit now calls. Behaviour on selection change is preserved. Also ports the upstream PR #8136 try/except guard onto the props.ifc_class write for the selection-driven path. Adds test_handler_forward_compat.py to pin both contracts via AST.

Add the mixin to the bases; rename _position_gizmos to position_gizmos so the mixin's refresh/draw_prepare dispatch lands correctly and drop the now-redundant overrides. * GizmoWallAddOpening's poll gated on the strict is_wall predicate, which rejects fillet-corner walls (no LAYER2 usage by IFC spec). Switch to is_path_connectable_wall on both the active and the partner-exclusion checks so the add-opening icon surfaces over curved corners — matching every other wall-state gizmo's host gate. * Show / hide openings was only available on LAYER2 walls because GizmoWallEdition's parametric edit pipeline (which carries the toggle) refuses fillet bodies. Add GizmoWallFilletToggleOpenings, a dedicated single-icon group that polls on is_fillet_corner_wall and reuses bim.toggle_wall_openings — the body stays untouched. Forward-compat AST guards in test_wall_gizmos_forward_compat.py pin both invariants: every wall GizmoGroup that calls self.get_decoration_colors() must inherit a mixin that provides it, and GizmoWallAddOpening.poll must keep using the looser predicate.

Port: * ``CycleRoofGenerationMethod`` operator (bim.cycle_roof_generation_method) cycles props.generation_method between "HEIGHT" and "ANGLE". Shift+click cycles in reverse via the ``CycleTypeMixin`` contract. * ``GizmoRoofEdition`` gizmo group: 3 dimension gizmos for height (visible in HEIGHT mode) / slope angle with tan/atan2 rise round-trip + degree formatter (ANGLE mode) / roof_thickness. All three handles anchor at the object's local origin and separate visually via their declared axes (height/slope +Z, thickness -Z) — height + slope are mutually exclusive via ``visibility_condition`` so they never paint at the same time. Anchoring at the origin sidesteps the first-click default-identity-matrix symptom that footprint-derived anchoring would have hit on a stale ``RoofData`` cache. * Lifecycle factory swap: explicit ``EnableEditingRoof / CancelEditingRoof / FinishEditingRoof`` classes replaced by ``tool.Parametric.build_edit_lifecycle("roof", _RoofEditMixin, ...)``. Same bl_idnames out, no external caller changes. * Registration: ``CycleRoofGenerationMethod`` + ``GizmoRoofEdition`` added to ``bim/module/model/__init__.py`` classes tuple. * Tests: ``test_roof_gizmos.py`` covering slope round-trip, visibility gates, cycle operator metadata, and origin-anchored positioning. Bug fixes: * ``generate_hipped_roof_bmesh`` flipped the bottom slab face's normal at low slope angles. The kernel's outward-inference becomes ambiguous on near-flat geometry once ``remove_doubles`` and internal-face deletion run, and the early ``recalc_face_normals`` pass at line 389 ran BEFORE the topology was final. A second pass on the final closed mesh fixes the eave plane (now reliably points down regardless of slope). * ``bpypolyskel.polygonize`` can emit a face whose vertex list contains the same index twice on certain footprint/slope combinations (a straight-skeleton ridge collapse). ``bm.faces.new`` rejects those with ``found the same (BMVert) used multiple times``, aborting the whole rebuild. Filter the degenerate faces out so the rest of the roof renders. * ``_RoofEditMixin._restore_viewport_after_cancel`` now rebuilds the bmesh from the just-restored draft via ``update_roof_modifier_bmesh``. The hook was abstract on ``PathPreservingEditMixin`` and raised ``NotImplementedError`` on cancel-after-edit, leaving the user stranded. Also folds in a parallel ``tool/loader.py`` swap from ``tool.Blender.Modifier.is_railing`` to ``tool.Parametric.is_railing`` (consistent with the rest of the loader using ``tool.Parametric.*``). Verified: headless smoke green, test_parametric_registry.py 8/8, test_roof_gizmos.py 15/15. ruff + black clean on the touched files.

Callers now reach the canonical home directly, and the shim block — seven is_ classmethods plus the inner class Array — comes out. Renames (no semantic change): * tool.Blender.Modifier.is_ → tool.Parametric.is_ 13 sites across tool/loader.py, bim/import_ifc.py, bim/module/geometry/{data,operator}.py, bim/module/model/{door, railing,roof,stair,ui,wall,window}.py. * tool.Blender.Modifier.Array. → tool.Array. 4 sites across tool/root.py, bim/import_ifc.py, bim/module/geometry/operator.py. * test_parametric_registry.py: the two getattr probes that hunt predicates by name now look on tool.Parametric. Docstring + the test function name (test_every_entry_has_modifier_predicate → test_every_entry_has_parametric_predicate) follow the move. Kept on tool.Blender.Modifier (non-shim, no equivalent on tool.Parametric): try_applying_edit_mode, try_canceling_editing_modifier_parameters_or_path, is_eligible_for__modifier (×5), is_array_child, is_slab. Verified: 109 model-lane tests + 8 parametric-registry tests pass (the one pre-existing failure in test_wall_header_refresh.py is unrelated — it patches handler.update_bim_tool_props which has been renamed). git grep for tool\.Blender\.Modifier\.(is_|Array\.) returns empty. black + ruff clean on every touched file.

The restore negated the sign — `Move(-mean)` instead of `Move(+mean)` — placing the swept solid at -mean (mirrored through the origin) rather than its true position. Only triggers for polyline directrixes (`is_polyhedron()`) whose centroid is more than 100 m from the origin (`mean.norm() > 1e2`), so models centered near the origin are unaffected.

Same XY at different Z collapses to a single screen pixel in plan / top view, so two icons became one hit target — invisible from above. * position_gizmos now always-stacks along screen-up at a wall-top anchor in both the joined (unjoin + fillet) and the intersecting (extend + join + fillet) states. Order bottom-up is extend / L / fillet. Collinear-merge keeps its single boundary icon (no stack needed). * New _stack_anchor_z picks the active wall's top Z (or the taller of the two on mid-selection-transition frames). New _stack_at lays a tuple of icons along screen-up at the resolved anchor. * Glyph swap: join_icon -> VIEW3D_GT_wall_corner (L), extend_to_wall_icon -> VIEW3D_GT_wall_tee (T). Both classes already existed in bim/module/drawing/gizmos.py from an earlier commit; only the setup() bl_idname strings changed. The previous arrow-merge / arrow-extend pair read as the same direction once stacked. Forward-compat AST contracts in test_wall_gizmos_forward_compat.py pin the new invariants: the L and T bl_idnames must appear in setup(), and position_gizmos must route through _stack_at so a regression that reintroduces a direct billboarded_at write for any state-specific icon fails CI before it flattens the stack again. Also folds in a one-line typo fix in core/spatial.py: assign_container's per-element can_contain check iterated `e` but predicate-tested `root_element` (the outer for-loop variable), so every element in the comprehension was tested against the same container/element pair.

Four preview paths, each gated on a specific icon's ``is_highlight`` state: * **Join intersection** — two LAYER2 walls selected in the ``intersect`` state (non-joined, non-collinear, non-parallel). Draws four lines: each wall's axis at both base and top Z, extending from the wall's nearer endpoint to the projected XY intersection. The pair of lines per wall communicates the full plane the join welds at, not just the floor edge. * **Cursor extend** — single LAYER2 wall, hover on ``extend_x_gizmo``. One line from the wall's nearer X endpoint to the cursor's projected X on the wall axis. * **Cursor extend-Z** — hover on ``extend_z_gizmo``. Vertical line at the cursor's projected X from wall base to cursor Z (the new total height). * **Cursor split** — hover on ``split_gizmo``. Vertical line at the cursor's projected X from wall base to wall top — the cut plane. Warning-red colour matches the icon's destructive-action signal. Hover colour rules for the join preview: * **Join or Fillet hover** → all four lines highlight in ``decorator_color_selected``. Both icons commit a symmetric corner meet, so every line is part of the operation. * **Extend-to-Wall hover** → only the non-active wall's two lines (base + top) highlight. The default-direction extend operator moves the non-active wall into the active one's axis; only that wall's preview should signal motion. * No hover → all four lines in ``decorations_colour``. Three coordinated changes: * ``bim/module/model/wall.py`` gains the ``_classify_wall_join_state`` wrapper over ``core.classify_wall_join_state`` (feeds the ``_are_walls_joined`` flag the core helper expects) AND a ``_active_instances`` per-region weakref ClassVar on ``GizmoWallJoinIntersection`` populated in ``setup()``. Without the weakref registration, the decorator's ``_lookup_active_instance`` call returns None every frame and the hover gates silently evaluate False — the symptom would be preview lines that never switch colour. Both pieces ported from gizmos-8088. * ``bim/module/model/decorator.py`` gains ``WallGizmoPreviewDecorator`` (~280 LOC across the four preview paths + shared helpers ``_stroke`` / ``_active_layer2_wall_for_gizmo_preview`` / ``_join_group_hover_state`` / ``_extended_wall_index``). All cross-file dependencies (``core.classify_wall_join_state``, ``core.wall_join_preview_lines``, ``_stroke_lines_alpha``, ``_cursor_icon_hovered``, ``_lookup_active_instance``, ``tool.Parametric.is_path_connectable_wall``, ``_wall_axis_world_segment_from_geom``) already on HEAD. * ``bim/handler.py`` wires ``WallGizmoPreviewDecorator.install()`` / ``.uninstall()`` alongside the other always-on preview decorators. The decorator self-polls every frame; cost is one selection-count check + one ``is_highlight`` read when no eligible state is active. Verified: headless smoke green, ruff + black clean. Live testing confirms the four preview paths fire correctly when hovering each icon.

GizmoHostAddOpening covers all three host types via is_supported_host, dispatching walls to the axis-projection anchor and slabs/roofs to a world-Z anchor lifted just above the host's top face (predictable height regardless of the void's vertical position). Show openings on hosts with their own parametric-edit toolbar — GizmoRoofEdition gains an idle-row toggle_openings_gizmo parallel to the wall's, parked at the cancel-slot X next to the pen. Visible only when the host carries HasOpenings and the edit triad is idle. Roof overrides get_element_height to return the mesh's world-AABB top in object-local Z, so the WHOLE pen-row anchors visibly above sloped or stepped roof bodies. The wall's idle-row toggle now also hides when HasOpenings is empty. Show openings on hosts WITHOUT a parametric-edit toolbar — GizmoHostToggleOpenings scoped strictly to the fallback case: a single host selected, HasOpenings non-empty, NOT a path-connectable wall, NOT a parametric roof. Covers slabs today plus any foreign-authored IfcRoof without BBIM_Roof. Anchored at object origin XY + world-AABB top Z. When slab parametric-edit eventually lands, the slab predicate joins the exclusion list and this gizmo's poll narrows automatically. Operator move — ToggleWallOpenings was already host-agnostic; renamed to ToggleHostOpenings in opening.py (bl_idname bim.toggle_host_openings). Three callers (the wall idle-row binding, GizmoWallFilletToggleOpenings, and workspace.py's hotkey_A_O for Alt+O) now route through the renamed operator. The Alt+O binding is surfaced in the operator's bl_description so it appears in F3 search and hover tooltips. DRY refactors — * GizmoWallAddOpening deleted (subsumed by GizmoHostAddOpening) * tool.Blender.get_object_world_bounding_box added as the world-AABB sibling of the existing local helper; 3 inline call sites in tool/misc.py (set_object_origin_to_bottom, scale_object_to_height) and gizmos.py adopt it (2 other sites in drawing/operator.py and project/operator.py inherently need raw transformed corners for per-corner plane / NDC tests — not AABB candidates) * BaseParametricGizmoGroup gains setup_pen_row_toggle_openings_icon + update_pen_row_toggle_openings_icon; wall + roof + any future host gizmo wire up the idle-row toggle with two one-line calls * _resolve_active_host shared poll prologue between the two host gizmos (gate + selection count + active-in-selected + entity lookup + supported-host check) * HasOpenings non-empty checks at 3 sites route through tool.Geometry.has_openings * hotkey_A_O body collapsed to bpy.ops.bim.toggle_host_openings() The forward-compat AST guard pinning "must accept fillet-corner walls" retargets from GizmoWallAddOpening.poll to is_supported_host.

The three bound operators (bim.extend_wall_to_cursor, bim.extend_wall_height_to_cursor, bim.split_wall_at_cursor) already poll on wall-selected and commit any pending wall edit before acting, so single-click without entering edit mode is now the canonical flow. Matches gizmos-8088's always-on behaviour. * Register GizmoWallEdition instances in a per-region weakref map (_active_instances) populated at setup_element_specific_gizmos time. The WallGizmoPreviewDecorator dereferences this map to read live is_highlight state off the cursor icons. Without the registration its _cursor_icon_hovered always returned False and the hover-gated GPU previews silently never drew. Mirrors the same pattern already in place on GizmoWallJoinIntersection. * Add post-operator resync to all three cursor operators (_maybe_resync_wall_props_from_ifc for the single-wall split / extend-height paths, _resync_walls_after_mutation for the selection-wide extend-X path). Without this, props.length / props.height stayed stale after the operator ran, so the orientation flips _apply_wall_extend_flips computes from cursor_local vs wall dimensions kept using the pre-extend values until the next selection change. Matches gizmos-8088's pattern. * Hover-gated GPU previews per icon: - extend-X: filled Z=0 floor quads spanning the wall's offset to offset+thickness Y band, visible from plan view without side- view clutter. Grow case (cursor beyond either endpoint): one green decorator_color_selected quad over the extension. Shrink case (cursor inside extent): green quad for the portion that REMAINS + red decorator_color_error quad for the portion the operator REMOVES. - extend-Z: vertical lines at the cursor's projected X in the wall's y=0 reference-line plane. Grow case (cursor above wall top): one green segment from z=height to z=cursor.z. Shrink case: green from z=0 to z=cursor.z (REMAINS) + red from z=cursor.z to z=height (REMOVES). - split: one red vertical line at the cursor's projected X from base to wall top — the cut plane. Quads use QUAD_ALPHA=0.25 so the underlying wall body stays visible. * New module-level _fill_quads_alpha helper next to _stroke_lines_alpha, plus a per-decorator _fill convenience method and a _wall_floor_quad corner builder. Modal-active gizmo hiding (is_gizmo_hidden_by_modal) is preserved.

DoorType has 8 IFC variants, WindowType 9, StairType 3 — so cycling past the target was the norm. Threshold rule for cycle-vs-menu: cycle is appropriate for exactly 2 values (advance-one-per-click stays predictable). Three or more values warrants a popup menu. Door / window / stair all qualify; roof (RoofGenerationMethod has 2 values) keeps cycle. Wall has no type cycle. Array is unaffected. Swap to the popup-menu pattern (PickTypeMixin already on HEAD at bim/parametric_lifecycle.py:442): clicking the icon opens a menu listing all type_literal values; selecting one applies it in a single undo step. The hamburger icon (VIEW3D_GT_menu) is wired into BaseParametricGizmoGroup.setup_editing_gizmos whenever pick_type_operator is set (mutually exclusive with cycle_type_operator). Matches gizmos-8088's pattern exactly. Per-feature shape: * door.py: PickDoorType replaces CycleDoorType. GizmoDoorEdition.cycle_type_operator → pick_type_operator. * window.py: PickWindowType replaces CycleWindowType. Same swap. * stair.py: PickStairType replaces CycleStairType (no tool.Ifc.Operator inheritance — stair-type changes BIMStairProperties only, no IFC mutation). Same swap. * bim/module/model/__init__.py: registration entries renamed Cycle* → Pick*. * bim/module/drawing/gizmos.py: drop the CycleTypeMixin / PickTypeMixin / TypeAccessorBase shim re-export — its own docstring already noted "PR5 cleanup drops these" and the three callers (door / window / stair Cycle*Type) it served are gone. Roof's CycleTypeMixin import was already direct from bim.parametric_lifecycle. Also update GizmoMenu docstring to reflect the 2-vs-3+ threshold.

That is the right default for "drag a fresh door onto a wall and let the model place it for me", but defeats the workflow where the user has already positioned the filling precisely (e.g. snapped to a window in an adjacent wall, copy- pasted at an exact Z, aligned to a reference object). Holding SHIFT while clicking the gizmo now opts into a "preserve placement" mode: the filling stays at its current matrix_world and the opening is created at the filling's existing position. The opening / filling rels and representation work are unchanged — only the snap-to-axis branch is skipped, so the IFC graph is identical to the regular click; only the spatial position of the filling differs (user-chosen vs auto-snapped). Implementation: * bim/module/void/operator.py: AddOpening gains a hidden preserve_placement BoolProperty + an invoke() that sets it from event.shift. The call into FilledOpeningGenerator.generate forwards the flag. bl_description documents the SHIFT modifier so it surfaces in F3 search / hover tooltip. * bim/module/model/opening.py: FilledOpeningGenerator.generate accepts preserve_placement (default False — backwards-compatible with the other caller, tool.Model.add_filled_opening). The voided_obj.data-gated snap block (raycast + axis projection + rl-Z default + filling_obj.matrix_world write) skips entirely when the flag is True. The opening's matrix_world reads from filling_obj.matrix_world below the gate, so the opening lands at the filling's preserved position automatically.

The Root placement is the right architectural home: has_material_styles pairs with assign_body_styles in the copy_class flow as "is there material-defined styling? if not, apply body styling" — both decisions live on the same interface, called in sequence from the same caller. The semantic delta (HasRepresentation vs IfcSurfaceStyle) is a close approximation in real IFC files where HasRepresentation almost always indicates a styled material; if precision becomes necessary, the Root impl can be tightened independently of this cleanup. Drop the Geometry method + its abstract declaration in core/tool.py. == Sanitation sweep per CLAUDE.md §4a == Eight rot-prone references in code we authored on this branch get their first-draft mistakes cleaned up. The §4a rule (no sibling symbol names, no test paths, no motivation history in docstrings) got added during this branch, so older commits sometimes named their siblings in prose; this is a focused cleanup of the worst offenders. * bim/module/model/wall.py:201 — _CommitWallDraftsFirstMixin docstring carried motivation history ("...that every multi-wall operator … used to repeat at the top of _execute"). Rewrite to describe only the current contract. * bim/module/model/wall.py:1910 — cycle_type_operator comment named two sibling methods. Rephrase to describe what happens at the slot. * bim/module/model/wall.py:2025 — _active_instances ClassVar comment named WallGizmoPreviewDecorator. Rephrase to "the wall-gizmo preview decorator" (role, not class). * bim/module/drawing/gizmos.py:3402 — GizmoFillet hit_uses_bbox comment named GizmoWallJoinIntersection. Rephrase to "the wall-join gizmo group". * bim/module/drawing/gizmos.py:3887 — GizmoCountLabel docstring had a :meth:`set_count` cross-reference. Drop — reader sees the method next to the class. * bim/module/model/host_add_opening_gizmo.py:201 — poll-exclusion comment named GizmoWallEdition + GizmoRoofEdition. Rephrase to describe why we skip ("walls and parametric roofs both render their own toggle in the pen row"). * bim/module/void/operator.py:45 — preserve_placement comment named FilledOpeningGenerator.generate. Rephrase to "the filling-opening generator gates its snap-to-wall-axis block on this flag". * bim/parametric_lifecycle.py:64 — module docstring named the test file path (test/bim/test_parametric_registry.py). Rewrite to "enforced by the registry contract tests". Sweep otherwise clean: no third-party software names in this-branch- authored comments (upstream Revit / Tekla / ArchiCAD references are legitimate external-constraint workarounds, §4a-allowed). No PR/issue numbers we authored except the FIXME(PR5) in tool/parametric.py:150, deliberately preserved until PR6's MEP slice resolves it.

Two changes resolve it. Gate the header refresh in tool.Parametric.refresh_post_commit on operator.bl_idname being one of the EDIT_TYPES finish_op idnames. Only validate-gizmo commits (bim.finish_editing_) now trigger the refresh; demo-loader and other non-edit operators skip it. Querying the registry directly is the canonical signal — string-prefix matching would silently drift if ParametricObject.finish_op changes derivation. Harden tool.Blender.get_active_object so its view_layer fallback also uses getattr; the 150+ callers routed through it now tolerate stripped contexts. _resolve_bim_tool_context applies the same defensive pattern to mode / workspace. Tests: - test_handler_restricted_context covers get_active_object's defensive path and the BimTool-family whitelist (excludes annotation, spatial, structural). - test_handler_forward_compat AST-pins that the gate consults EDIT_TYPES (not a string prefix). - test_wall_header_refresh rewritten — three tests cover the gated-by-registry contract: counter bumps for every commit, finish_op operators refresh headers, others don't. Hotkey-driven in-place edits (S_E / C_E) no longer trigger the refresh — they were caught by the pre-refactor "every commit" design. Left out of scope; the new skip-non-finish test pins this as intentional.

Without this guard, a failed enable (e.g. on a wall without IfcMaterialLayerSetUsage) leaves is_editing False but a press on finish still walked the sub-ops below, which dereferenced layer-set-dependent state and crashed. * tool/model.py: Model.offset_wall now guards against ifcopenshell.util.element.get_material returning None before calling .is_a("IfcMaterialLayerSetUsage"). Fixes the pre-existing test/bim/module/model/test_wall_header_refresh.py crash that has been the only failing test in the wall lane since this branch started. * bim/handler.py: _apply_save_file_invariants drains wall_offset_gizmos.clear_caches() on load_post. The module-scope GenerationKeyedCache instance survives the .blend reload; without the drain the cache may serve entries whose bpy_struct references point into the freed bpy.data of the previous file. * test/bim/test_handler_forward_compat.py: AST-walk test that enumerates every bim/module/model/*.py source declaring both a module-scope GenerationKeyedCache assignment AND a top-level clear_caches function, and asserts each module appears as a .clear_caches() call in _apply_save_file_invariants. Pins the contract: any future module-scope geom cache that exposes clear_caches must wire into the load_post drain. * test/bim/feature/model.feature + test/bim/test_feature.py: wall edit-lifecycle scenarios switch from "add cube + assign as IfcWallType" to "load the demo construction library + add an occurrence of the WAL100 wall type", so the parametric edit runs against a real LAYER2 wall with IfcMaterialLayerSetUsage rather than a vanilla-mesh promotion that lacks one. The demo-library step also picks the schema-matching library file (IFC2X3 / IFC4 / IFC4X3) so the appended types remain valid across schemas.

The (max - min) per-axis extent — which callers previously computed via local helpers — is now a key alongside min_x / max_x / min_point / max_point / center. Distinct from Blender's built-in obj.dimensions (which folds object-level scale): the local variant is the intrinsic mesh bbox extent; the world variant is the matrix_world-applied AABB. * bim/module/model/array.py: drop the local _bbox_dims helper; the two callers now read tool.Blender.get_object_bounding_box["dimensions"] directly. * Rename _parent_geometry_changed -> _array_children_need_rebuild. The old name suggested "did the parent change just now", implying the function was a parent-edit-finish trigger. It actually runs only inside the array-edit-finish path as a drift safety net (the upstream-deliberate design — see commit 83d97d7e9 "Fix #7616. Make regenerate array an operator instead of an array preference" — means the array doesn't auto-regen when its parent geometry edits finish). New name matches the call-site phrasing ``if X: _wipe_array_children(layers)`` and clarifies that this is a children-state check, not a parent-edit trigger. * Extract _resolve_array_edit_props(context) — returns the active object's array props during an active edit lifecycle, or None. Collapses the obj-active-then-is-editing prologue (3 lines + return) to one resolver call across 4 sites: ToggleArrayMethod.execute, AdjustArrayCount.execute, RemoveArrayLayerFromEdit._execute and .poll. Each call site shrinks from 7 lines to 3. * Migrate two inline bbox reads inside GizmoArrayEdition to the new dict keys: get_axis_world_face_center collapses the manual xs/ys/zs min/max + center math to bbox["center"] + bbox["max_x"] / ["max_y"] / ["max_z"]; get_element_height collapses ``max(corner[2] for corner in obj.bound_box)`` to tool.Blender.get_object_bounding_box(obj)["max_z"]. The _BBOX_EQUALITY_EPS = 1e-5 tolerance stays inline as a single- consumer constant — no other call site needs tolerance-equality on dimension tuples, so extracting it to a shared util would be speculative abstraction. == Drop dead code == * GizmoArrayEdition.update_editing_gizmos override + its _has_other_parametric_type helper: redundant with hide_pen_button = True at line 1024. The base class already hides the pen in every idle case (when hide_pen_button is truthy) AND in every editing case (unconditionally). The override's conditional hide-when-parametric only re-hid a pen that was already hidden in both branches. Removes the only remaining path that could re-show the array's pen icon; array-edit entry is now uniformly via the per-layer ARRAY icons (which is the documented preferred affordance, see the hide_pen_button comment). * _wall_fillet_preview_active in wall.py: defined but never called. _wall_fillet_props (the sibling thin-wrapper around preview_base.get_preview_props) is heavily used; the is_preview_active wrapper was added speculatively and never picked up a consumer.

charset=UTF-8 Content-Transfer-Encoding: 8bit bim/handler.py was importing two feature-module internals (wall_offset_gizmos.clear_caches, preview_base.discard_pending_previews) to drain load-transient parametric state alongside the existing tool.Parametric.heal_stale_edit_flags() call inside _apply_save_file_invariants. Each new parametric drain added one top-level import and one inline call — every load_post drain leaked into handler.py's namespace. Hide all three drains behind tool.Parametric.on_load_post(scene), sited adjacent to heal_stale_edit_flags. The two feature-module imports become late imports inside on_load_post — same pattern as refresh_post_commit's existing `import bonsai.bim.handler` — which sidesteps the tool.parametric -> bim.module.model.preview_base -> bonsai.tool registration-time cycle. The forward-compat AST contract that pinned "every module-scope GenerationKeyedCache + clear_caches MUST be drained on load_post" follows the call site to its new home — the test now walks tool.Parametric.on_load_post instead of _apply_save_file_invariants. No behaviour change. 45/45 affected bim tests pass (test_handler_forward_compat, test_preview_base, test_wall_offset_gizmos, test_parametric_registry). ruff + black clean on all touched files.

The result on a typical extend / split / unjoin action: the icon sits on top of the cursor crosshair (or the corner the user wants to click), defeating precise positioning. Add shared ``gizmo.top_down_clearance(context, billboard_rot)`` to bim/module/drawing/gizmos.py: returns a screen-up Vector in top-down view (cosine cone around world Z, matching ``is_view_top_down``) and a zero Vector elsewhere, so call sites apply it unconditionally before ``billboarded_at``. Default distance 0.4 m aligns with the inter-icon stack spacing already used by GizmoWallJoinIntersection so single icons and stack bases land at consistent screen-up positions when multiple groups render around the same wall endpoint. Apply at the seven wall-edit anchor sites: * GizmoWallEdition cursor stack (top-down branch only — non-top-down already stacks along world-Z at structural points clear of the cursor). * GizmoWallExtendVertically (single icon at wall origin endpoint, active-object Z elevation). * GizmoWallJoinIntersection corner stack base + merge midpoint. * GizmoWallUnjoinSingle link-toggle pool (one icon per IFC path connection, previously sitting exactly on the connection point). * GizmoWallFilletReedit pen icon at fillet corner. * GizmoWallFilletToggleOpenings. The clearance is a pure visual offset — bound operators still read the world-space anchor (cursor / endpoint / connection point) at execute time, so the action's target is unaffected.

On an arrayed wall the dict was shadowed: find_for_element returns "array" before "wall" in EDIT_TYPES order, the wall reservation was never consulted, and the first per-layer ARRAY icon (local X=0.37) landed 13cm from the wall's toggle_openings (X=0.50) — visually on top of each other. Promote idle-row icons into the slot system instead of patching the dict: * IconSlot gains an Optional visible_when predicate for state-driven visibility (toggle_openings only when the host carries openings). * BaseParametricGizmoGroup gains idle_slots: ClassVar[tuple[IconSlot]] + _idle_slot_x_positions() + _idle_row_right_edge() helpers; the setup + idle-branch positioning loops mirror the existing feature_slots path. * Wall and roof declare toggle_openings as an idle_slot and drop their ad-hoc setup/update calls. * GizmoArrayEdition's _resolve_feature_idle_max_x walks BaseParametricGizmoGroup.REGISTRY and takes the max _idle_row_right_edge() across peers whose poll passes — no more hardcoded dict, no more find_for_element-order shadowing. * setup_pen_row_toggle_openings_icon + update_pen_row_toggle_openings_icon helpers deleted from drawing/gizmos.py. * 3 forward-compat AST guards pin the new contract. Also bundles an unrelated array-test fix: TestUsingArrays in test/tool/test_model.py was asserting against bpy.context.selected_objects which is a fragile signal after remove_array / apply_array. A new _array_objects() helper filters bpy.data.objects via the BIM_Array pset's IfcActuator type instead. Layout on an arrayed wall after the fix: pen X = 0.00 toggle X = 0.50 (idle_slot 0) array[0] X = 0.87 (one ICON_ARRAY_GAP past idle row) array[1] X = 1.27 All separated by the standard inter-icon spacing.

Blender does not push an undo step for a raised operator (the same gap that the CANCELLED-modal arm patches via bpy.ops.ed.undo_push), so the WARNING the framework can emit is only honest if it pushes that undo step too. The framework now detects partial state via ifc_file.transaction.operations, pushes a Recover undo step, then reports a WARNING naming Ctrl+Z so the recovery path is discoverable. The bespoke try/except wrapper in UnjoinWallPathConnection becomes redundant and is retired in the same change.

While Blender's transform modal (G/R/S and the Bonsai macro overrides) drags the matrix, the gizmos slide off-cursor and fight the transform overlay. Detect via context.window.modal_operators (Blender 4.2+) — the collection of running modal operators. Gate poll() (forward-compat) and draw_prepare() (production path: gizmo.hide=True preserves the GizmoGroup across the drag instead of destroying it). Cover the Bonsai macro override for G key (and Shift/Alt/Ctrl+Shift+D) by matching the BIM_OT_* macro idnames that surface in modal_operators. Forward-compat test walks every parametric-edit module for GizmoGroup subclasses and asserts poll returns False with the detector mocked, so new gizmo groups inherit the hide automatically.

This commit ports the per-segment parametric edit triad (enable / finish / cancel) plus a cursor-anchored extend operator and a cursor-projected split operator into one gizmo group per segment type. The two PropertyGroups (BIMPipeSegmentProperties, BIMDuctSegmentProperties) host the draft length plus snap fields so cancel / no-op-finish restore the segment to its exact pre-edit visual state including a non-identity pre-edit scale. Length commits are written through DumbProfileJoiner.set_depth and auto-dispatch bim.regenerate_distribution_element so adjacent fittings track the port move. The split operator preserves downstream port connectivity and runs through tool.Ifc.run for single-step undo. The two segment types are now first-class entries in tool.Parametric.EDIT_TYPES, which resolves the FIXME on auto-commit-on-save dispatch. 35 unit tests cover predicate truth tables, segment_world_length geometry, preview-via-scale / restore-scale helpers, gizmo class wiring, lifecycle operator registration, dimension matrix_position rotation respect, and lifecycle drift-handling. The 6 extend- preview-line decorator tests stay deferred until the bend preview decorator commit lands MEPSegmentExtendPreviewDecorator.

For an IfcDoor the filled-void hop redirects to the IfcOpeningElement, then voided-element to the host wall, so a user who selects a door and runs bim.assign_container ends up targeting the wall — and silently no-ops on the door if the wall is already in the target storey. Per IFC4 / IFC4.3 (IfcDoor, IfcWindow): the spatial containment of a filling is defined independently of the filling relationship. Major exporters (Revit, ArchiCAD, Tekla, Allplan) emit independent ContainedInStructure on doors / windows accordingly. Drop the filled-void / voided-element hops from the walk; aggregate and nest remain — those are true sub-part relationships where the parent legitimately owns the container. New TestGetRootElement in test/tool pins the new contract (filling resolves to itself) plus the retained aggregate / nest / loose-element paths so a future PR that re-adds either hop is caught. Two new TestAssignContainer cases in test/core pin filling-to-self through the core layer and per-element can_contain filtering.

+0200 Subject: [PATCH 195/221] Add MEP bend preview decorator + join dispatcher MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The bend preview gizmo group (commit 2) populated a Scene draft but the user saw nothing in the viewport until they hit finish — they had to commit blindly. This commit ports the BendPreviewDecorator (centerline arc + two leg projections on valid geometry, warning-red axes on invalid in-segment intersections) and the interactive GizmoBendPreview group (three dimension widgets for start_length / end_length / radius plus validate / cancel icons). The bend axis math lives in a pure compute_bend_preview_polylines helper, fed into both the gizmo group's per-frame positioning and the GPU decorator's draw path. MEPSegmentExtendPreviewDecorator lands at the same time because it shares the decorator install / uninstall plumbing — renders the extend-to-cursor preview line for the GizmoPipeSegmentEdition / GizmoDuctSegmentEdition extend icons when hovered, clamping the projected endpoint to the operator's minimum so the preview matches where the commit lands. The MEPJoinSegments dispatcher routes two selected MEP segments to mep_add_transition (parallel) or enable_bend_preview (non-parallel) — the F3 search entry point that makes the bend preview testable before the gizmo-icon dispatch lands. 11 new tests in test_mep_bend_preview.py cover the geometry helper truth table (parallel rejection, right-angle happy path, near- collinear rejection, in-segment invalid_axes), the _intersection_past_near parametrized boundary, registration probes for the lifecycle operators / join dispatcher / gizmo group / decorator, and the FinishBendPreview RuntimeError catch contract. 6 extend-preview-line tests (deferred from commit 3) join the existing 35 in test_mep_segment_edition.py.

From 8c732ac3fa9d58701f041cd9d26292e3b85300d5 Mon Sep 17 00:00:00 2001 From: Gorgious56 Date: Tue, 9 Jun 2026 11:51:37 +0200 Subject: [PATCH 196/221] Align extend gizmo arrow with segment axis MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The extend icon used a pure screen-space billboard that always pointed +X across the screen — the arrow ran horizontally regardless of the pipe / duct's orientation. The new billboarded_along_axis helper rotates the gizmo about the camera- forward axis so its local +X aligns with the segment's local +Z projected onto the screen, keeping the icon camera-facing but visually following the extrusion direction. The flip-mirror branch now reads from cursor-vs-current-end along the segment axis (not screen-X), so the arrow points away from the current endpoint regardless of viewport orientation. The split icon stacks perpendicular to the rotated extend arrow in screen space so the two don't overlap. The decorator's green preview line no longer clamps the cursor projection to min_projected_length — it follows the raw projection so the line stays visible when the cursor crosses behind the segment origin (the user still sees where they're pointing even though the operator floors the actual commit).

charset=UTF-8 Content-Transfer-Encoding: 8bit The MEP one-shot operators (join, unjoin variants, terminal removal, path-select, obstruction add/remove) had no viewport surface. This commit adds GizmoMEPActions — the icon-action gizmo group that surfaces them as billboarded icons around selected MEP elements. Three anchor regions: a horizontal row above the bbox top (selection-cardinality icons), per-port endpoints for the three-state lock / unjoin icons (open lock for PORT_FREE, closed for PORT_TERMINAL, unjoin for PORT_JOINED — resolved per-frame from port_connection_state), and the predicted join location (compute_mep_join_location, shared with the bend preview) for the join / unjoin_pair pair. Unjoin icons render at full DEFAULT_BILLBOARD_SCALE with warning-red hover; endpoint lock icons shrink so the lock row stays subordinate to the row icons. The group hides itself entirely while a bend preview is active. MEPAddObstruction grew a position enum (CURSOR / START / END) and a mode enum (ADD / REMOVE / TOGGLE) so the gizmo can target a specific port without touching the cursor and dispatch ADD or REMOVE based on the click target — the lock_open icons drive ADD with position pinned, the lock_closed icons drive bim.mep_remove_terminal_fitting. Without the new fields the gizmo wiring (op_props.position = ...) crashed at setup() with AttributeError on the obstruction operator. validate_bend_preconditions extracts the type-match and profile-kind checks MEPAddBend enforces so EnableBendPreview surfaces the rejection immediately — the user no longer tunes a preview only to learn at commit time that the segments use an unsupported profile (e.g. IfcArbitraryClosedProfileDef).

Click forms a T-junction; shift+click forms an L-corner with the source wall trimmed at the projection, keeping its longer portion. The branch inherits the source's spatial container and centerline baseline so its authored axis matches the source's alignment rather than the type's default. Also includes a floor-plane preview quad for the new gizmo, a floor-Z cross line on the split preview for top-down visibility, a small bump to QUAD_ALPHA for clearer preview fills, and a stacking-offset helper that centralises the cursor-row screen-up step across three call sites.

Until upstream is fixed, MEPAddBend captures the bend centerline in world space before the segments are extended (otherwise the post-extension axes no longer reach the original intersection and arc reconstruction is wrong), then after the fitting is placed it hand-meshes the bend body and swaps the type's swept-disk representation for an IfcTessellatedFaceSet via tool.Geometry.export_mesh_to_tessellation + tool.Model. replace_object_ifc_representation. The centerline includes the straight start_length / end_length legs in addition to the arc so the bend covers the full segment-to- segment span. Sweep uses parallel-transport framing — each ring's (right, up) basis is rotated by the minimum rotation that maps the previous tangent to the current one, eliminating the twist a fixed world-axis reference produces when the tangent crosses the reference. Cross-section orientation seeds from the source segment's matrix_world local +X / +Y so asymmetric IfcRectangleProfileDef ducts land with XDim / YDim on the same axes the segment expects; parallel transport then preserves that alignment around the arc. Centerline radius is radius + profile_dim[lateral_axis] to match MEPAddBend's ref_point_radius — without this offset, the bend legs fall short of the extended segments by profile_dim * tan(angle/2). Face winding is left to the caller to correct via bmesh.ops.recalc_face_normals on the closed bend tube. Two FIXME(#8106) markers (capture site + helper call site) so both can be dropped once upstream lands a swept-disk round-trip fix.

From 2c3935bf9d9369bbcdc6598cbae36d464fe7fbd7 Mon Sep 17 00:00:00 2001 From: Gorgious56 Date: Tue, 9 Jun 2026 16:13:59 +0200 Subject: [PATCH 201/221] Add readonly door swing arc preview MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Selecting a Bonsai-parametric IfcDoor now shows the swing arc(s) without entering edit mode. A new viewport decorator polls on the active object, reads the door's BBIM_Door pset, and draws the same arcs the parametric door swing gizmo would draw — matching the hinge / panel-width / x-mirror contract minus the is_editing gate. A forward-compat test walks every door operation type and cross- checks the readonly decorator's arc selection against the gizmo's swing-arc config table, so future enum additions fail in both surfaces simultaneously. Also disables the inherited 8-pass dark halo on GizmoArc: an open curve has no enclosed silhouette, so the offset passes read as ghost arcs rather than a uniform outline. The arc's own cross- section thickness keeps it legible without the halo.

merge also orphans a GUID listed in the parent's ``BBIM_Array.Data``. Add a central ``tool.Blender.Modifier.any_selected_is_array_child`` predicate and gate the five wall topology gizmo groups plus the six bound operators behind it. Operator gating is defence in depth against keymap / F3 invocation paths that bypass the gizmo. The base ``_wall_gizmo_poll_gate`` keeps its loose two-check shape (viewport gizmos + no preview). A new ``_wall_topology_gizmo_poll_gate`` wraps it with the array-child filter and is what the topology gizmos use. Host-opening gizmos deliberately stay on the loose gate: openings authored on a child are preserved through ``regenerate_array`` and track with the replicated instance. A forward-compat AST guard walks wall.py for ``GizmoGroup`` subclasses and asserts each routes its poll through the tighter gate or the central predicate, with an allow-list for the parametric-edit and preview-owner exceptions. New wall topology gizmos inherit the contract by construction.

EnableBendPreviewFromBend re-opens the preview on an existing parametric bend: it walks the bend's ports to resolve the two connected segments, reads start / end length and radius from the bend type's BBIM_Fitting pset, and sets editing_bend_id on the preview props. MEPAddBend then deletes the old bend + its port connections (single undo step) before the recreate path runs, so finish replaces the bend in place and cancel discards the edit without touching the original. GizmoMEPActions surfaces a pen icon on single bend-fitting selections via the new _active_is_bend_fitting predicate; the icon dispatches the new operator. Mirror of the wall fillet re-edit flow (EnableWallFilletPreviewFromCorner + editing_corner_id in CreateWallFillet). Test coverage: registration probe for the new operator, an attached editing_bend_id field probe on the preview umbrella, and a parametrized truth-table for the _is_bend_fitting predicate (IfcFlowFitting with BEND PredefinedType, with other PredefinedType, with no type, IfcFlowSegment, IfcWall, None).

Add a confirmation dialog at the pen-icon dispatcher (the single chokepoint every feature routes through) showing the sibling count, with a session-scoped suppress checkbox. The check is read-only: tool.Model.get_sibling_occurrence_count wraps tool.Geometry.get_elements_by_representation against the resolved body rep and subtracts self + type. A forward-compat AST guard pins the dispatcher monopoly so any future feature that binds pen_gizmo directly to a feature-specific enable op fails the test before merge.

The visible front pass also inherited the source decorator color's modest alpha, so the outline read as subtle on both sides. Replace with a CAD hidden-line convention: solid full-alpha front pass on the visible side, world-space dashed back pass on the occluded side. Both passes use POLYLINE_UNIFORM_COLOR so depth and line-weight paths match. The dashed batch is built once per object epoch by a new pure helper tool.Blender.build_dashed_line_segments (pre-segments edges into world- space dash chunks), then cached via the existing batch-cache mechanism under "_dashed". The solid front pass is rendered at a slightly wider line width than the dashed back pass so its halo overpowers Blender's WIRE-display overlay bias at outline pixels — without the asymmetry the wire's anti-z-fight forward bias makes the LESS_EQUAL comparison narrowly fail and the dashed pass wins on visible edges too.
