The single-wall unjoin gizmo needs to enumerate every
IfcRelConnectsPathElements a wall participates in, regardless of which
side of the rel the wall was authored on, and place an icon at each
join's physical location. Two helpers carry that work:
_path_connection_location_world wraps core.compute_path_connection_location
at the Vector boundary. _iter_path_connections walks ConnectedTo +
ConnectedFrom, normalises orientation to (other, self_ct, other_ct),
and filters non-wall partners + None refs so per-frame gizmo positioning
survives malformed IFC.

Two paired test files for the framework infrastructure landed
earlier in this PR.
test_decorator_cache.py (11 tests):
* The 4-hook invalidation list (depsgraph_update_post + undo_post +
redo_post + load_post) is symmetrically managed by
install_decorator_cache_handlers / uninstall_decorator_cache_handlers.
A future edit that drops a hook from one side without the other
would land as a Blender segfault when a cached bpy.types.Object
ref outlives its underlying ID block — the regression must surface
as a test failure first.
* install is idempotent (calling twice doesn't double-register).
* uninstall when not installed doesn't raise.
* The bump handler accepts Blender's variadic args.
* The depsgraph predicate gates correctly: bumps on Object geometry
or transform updates, silently skips on Material / NodeTree / Image
updates (which would otherwise rebuild every cache on every node
edit).
* TokenCache.get_or_compute short-circuits on key+token match and
recomputes when the token bumps.
test_undo_resync_parametric_drafts.py (3 tests):
* UNDO_REGENERATORS keys must all be in tool.Parametric.EDIT_TYPES.
A typo would silently no-op on Ctrl+Z, restoring the desync the
helper is meant to prevent.
* The dispatcher skips objects with no active parametric edit
(undo_post fires for every undo, most of which touch zero drafts).
* The dispatcher silently skips parametric types that have no
UNDO_REGENERATORS entry (door / window / array are IFC-derived
with no draft preview mesh — they don't need a regenerator).
Mocks use spec=bpy.types.Depsgraph / spec=bpy.types.DepsgraphUpdate
/ spec=tool.parametric.ParametricObject so typos in mocked-attribute
access fail loudly (CLAUDE.md test discipline).

Splitting a wall through a door orphaned the door (door.FillsVoids
became empty). The fill rel was being reassigned by setting its
RelatedBuildingElement slot — schema-wise that's the filling slot, not
the wall slot — so when remove_feature deleted the old opening it
also cascade-removed the rel. Transferring via RelatingOpeningElement
keeps the rel pointing at the new opening so the door stays
associated. Pre-existing bug from 5a6476a57, surfaced by ef144dce2.

DumbWallJoiner.split assigned openings by projecting the opening's
centre-point onto the wall axis, so any opening whose footprint
straddled the cut was silently dropped from whichever wall its centre
missed. Now the full axis-projected extent (via ifcopenshell.geom.
create_shape) drives the assignment; for filled openings whose void
straddles the cut, a pure-void copy is added back to the neighbour
wall so its body is also cut.

Ctrl+Z / Ctrl+Shift+Z on an in-progress parametric draft (wall /
stair / roof) used to leave the preview mesh frozen in its
pre-undo shape — the IFC mutation rolls back but the bmesh built
from draft props doesn't repaint.
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/*``.

Three changes to the shared Enable/Finish/Cancel mixins:
1. 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.

Surfaces any regression in:
* the modules dict in bim/__init__.py (added a folder, forgot the entry)
* PointerProperty wiring on bpy.types.{Scene,Object,...}
* registry-driven GizmoPreferences<Name> auto-registration in
tool.Parametric.iter_gizmo_preference_classes
* bpy.app.handlers append/remove balance
* every register()/unregister() across the 45+ feature modules
as a single PASSED/FAILED test instead of the silent "addon failed to
enable" users encounter in a fresh Blender. Paired with the existing
test_parametric_registry.py contract tests, this catches both the
registry-shape regressions (operators/PropertyGroups/predicates) and
the registration-mechanics regressions (PointerProperty types not
registered before their owners).

test_parametric_lifecycle.py covers the door/window/railing/roof
state-transition contracts (enable/finish/cancel; no-op on
non-matching elements; draft preserved on finish-time failure)
that the registry smoke test never exercised.
test_parametric_registry.py gains a check that every is_<name>
predicate stays total (never raises on a non-matching IFC entity)
— a raising predicate would break the save path for unrelated
types. Also rewrites the gizmo-prefs check to read __annotations__
instead of hasattr, which depended on Blender registration timing.

Aligns with the test/bim/ convention: heavy imports go inside test
functions so the autouse _require_real_bpy fixture skips cleanly
when bpy is mocked, rather than module-level imports failing at
collection time and erroring out the whole file.

When two GizmoDimension hit regions overlap (a short dimension
nested inside a longer one along the same axis), the larger one
used to win because hit boxes are scaled by world-space length —
the long box fully contains the short one, leaving the short
gizmo unreachable. The larger gizmo stays clickable at its
exposed ends, so smaller-wins is the right UX default.
Sets self.select_bias = -self._dimension_length inside
GizmoDimension.set_dimension_length. The smaller gizmo writes a
less-negative depth value in the GPU select buffer and wins the
tie-break. select_bias is unused elsewhere in the codebase, so
icon and arrow gizmos keep bias=0 and are unaffected (icons
correctly still win against dimensions, since 0 > -length).
Adds test/bim/module/drawing/test_dimension_gizmo_priority.py
with 5 cases: direct ordering, monotonicity across length ranges,
abs() handling for signed dimensions, and NaN/Inf safety.

set_icon_gizmo_position computed
``mw @ (Translation @ billboard_rot @ Scale)`` — the object's world
matrix was applied AFTER the billboard rotation, so any non-trivial
object rotation (e.g. a wall rotated in plan, a stair rotated to
match a corridor) carried over into the icon's transform and tilted
it edge-on to the camera instead of facing it.
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.

Walls gain in-viewport parametric editing matching the door/window/stair
UX: drag handles for length, height, slope (x-angle), layer baseline
cycle, plus cursor-anchored quality-of-life operators (split at cursor,
extend to cursor, extend height, rotate 90, toggle openings) and
two-object state-machine gizmos (unjoin / merge / join-corner /
extend-to-wall / extend-vertically / add-opening).
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.

Establish a single source of truth for parametric element types (door,
window, stair, railing, roof). tool.Parametric.EDIT_TYPES drives:
- BIM<Name>Properties PointerProperty attachment via the registry
- GizmoPreferences<Name> class registration in bim/__init__.py
- save-time auto-commit of pending draft edits
- the refresh_post_commit epilogue called from IfcStore after every IFC
mutation, which fixes the stale-header bug where in-place hotkey
mutations (S_E / C_E) left BIMModelProperties and the gizmo cache
pointing at obsolete values.
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.

When a project has a ifc file associated, selecting non-ifc objects and duplicating them with SHIFT + D now correctly both duplicate them, keep the new objects selected and starts the transform modal. IFC objects behaviour is unaffected.
Fix#7034
bpy.ops.bim.extend_to_underside doesn't exist - the correct operator
name is bim.extend_walls_to_underside. The AttributeError killed the
entire panel draw, hiding mirror, align, aggregation, and QTO buttons.

Add tests for all four covering generation operators: flooring/ceiling
from walls and flooring/ceiling from cursor. Previously only flooring
from walls was tested.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Previously, there was a dance between invoke, execute, and draw. This
can probably be resolved, but is a high-risk for undo bugs. This
simplifies the logic flow to just a traditional _invoke -> _execute.
I add a new feature test to at least make sure it does something, and
this also fixes the segfault in tool tests as it no longer requires the
launching of the file browser.
* Linked IFC projects enhancement (multiple links to same project file)
- Implement link management system using UUIDs as identifiers to support multiple links to the same IFC file
- Add georeferencing compatibility detection and UI display (NONE, NOT_COMPATIBLE, PARTIAL_COMPATIBLE, FULL_COMPATIBLE)
- Support for duplicate link creation with Shift+D shortcut and automatic position offset
- Add false origin and project north calculation from 3D cursor for MANUAL mode
- Only store one cache per file, regardless of the amount of links
- Prevent duplicate links based on filepath and position comparison
- Improve error handling for missing files and loading failures
- Update tests
* Remove duplicate georef UI
I try to avoid duplicate UI (especially for one that can be as
sophisticated as georef - e.g. missing is WCS) as it means double the
code, double the tests, potential user confusion. BTW the note about
vertical datum isn't quite accurate as it may be included in the CRS
definition so vertical datum is optional.
* Remove depsgraph_update_post handler for update_link_ui_on_transform as per core developer feedback
* Move get_projected_crs to geolocation module
* Refactor get_projected_crs to simplify as per core developer feedback
* Remove unused import of bonsai.tool from project module
* Use IfcDocumentInformation per linked file and IfcDocumentReference for locaiton information
* Refactor SaveBlendMetadataFile operator to remove try-except blocks and remove linked projects collections since they are recreated by bonsai
* Cleanup removing empty collection instances for linked models in metadata.blend file and call determine_georeferencing_compatibility on link reload
* Add locking mechanism for linked models and update UI to reflect lock status
* Update logic that track IFC to execute_ifc_duplicate_operator instead of having it in execute() which does not track IFC undo/redo
* Refactor link handling to use get_link_empty_handle and set_link_empty_handle methods which in turn use the standard blender-ifc integrations patters (tool.Ifc.get_object(doc_reference) and tool.Ifc.link(doc_reference, empty_handle)
* remove operator.DuplicateLink and move it to tool.Project.duplicate_link()
* Refactor link handling to use sequential identifiers (no need for STEP ID DocRef)
* Refactor IFC linking logic to handle cases without a parent IFC file loaded. Firts link flase origin becomes parent origin
* Lock should not affect selection.
This makes it consistent with grid / spatial lock, and also toggle
selectability is already implemented.
* Remove unnecessary check for loaded library as Blender seems to do this internally already
* Rename util to get_crs because in IFC4X3 you can also have geographic CRS not just projected
* Remove unnecessary call to determine_georeferencing_compatibility
This function is already always called prior to calculate_link_position
so shouldn't be called here. It's also a very expensive function: as it
currently stands, just to link a single IFC, ifcopenshell.open() is
called 3 times. This reduces it to 2.
* Store CRS as metadata for linked models, and compare metadata when indicating georeferencing compatibility
Previously, to check georeferencing compatibility, ifcopenshell.open()
was used. When linking large models, this adds considerable time and
memory usage. This instead captures the georef as standard metadata in
our .cache.json. This now reduces the ifcopenshell.open() calls back
down to only 1 as necessary (see previous commit).
* Use link index instead of link name to fetch link collection item
Link name runs into issues with name uniqueness. This is why you created
a function for "get next link ID". After this refactoring, we can no
longer worry about uniqueness and that function may be removed.
* Simplify reloadlink into just unload and reload (with cache disabled)
This function should not be responsible for editing any data.
* Remove unnecessary get_next_link_id as names no longer need uniqueness
This now frees up the name variable to track a more meaningful, human
name like IfcDocumentInformation's Name attribute.
* Rewrite get / set link_empty_handle to just use the link directly
This prevents needless logic to fetch the link and also removes issues
related to duplicate names.
* Temporarily remove logic in prop callback
Right now, pretty much all the logic is done in a prop callback. In
general logic in prop callbacks should be minimised, since it's hard to
test and easily triggered as a domino effect of another change, and may
also impact undo/redo.
* Remove code that unnecessarily removes cache
This code removes cache, which means any project unlinking an IFC auto
clears the cache for any other project which doesn't make sense, and
also breaks the ability to readd it quickly.
* Rewrite link, unlink, load, and unload IFC
There were a few issues tackled here:
- Operators that change any IFC data must use tool.Ifc.Operator and
_execute, otherwise undo/redo will break. That's one of the risks of
using prop callbacks, as it is not explicit when an IFC edit happens.
- The usage of IfcDocumentReference was not correct. The Location
should store the URL, _not_ the position. The position should be in the
Identification attribute.
- The URL was stored in IfcDocumentInformation location, which does not
work in IFC2X3. There are a few changes here to make it IFC2X3
compatible.
- Generally move logic in operators, not prop callback.
* Remove restriction around manual mode.
Users should be able to use manual mode if they want.
* Restore AUTOMATIC mode to identical behaviour to file open
This is the first step to reusing cache files agnostic of the host.
* Revert tests for a fresh start for updating tests
* Revert "test_feature - clean up .ifc.cache. files after test was executed"
This reverts commit 99ae768ddf.
* Update tests and reimplement calculations for matrix of empty handle
Previously, the empty would always be placed at the origin, unless a
"position" offset was present. This is a problem, because the "position"
is simply a local offset relative to the Blender cache! If the cache was
regenerated, the offsets would be outdated. Also, the cache appeared in
different locations depending on the false origin mode, so the offset
would mean different things to different people.
Instead, a more robust method is:
1. When you link a file, a Blender cache is generated. The Blender
origin of this cache is arbitrary! It depends on the user's false origin
mode and is purely a Blender session specific thing.
2. When you load a link, a link is _always_ loaded into the correct
location with regards to IFC global coordinates. All math is done from
the perspective of IFC.
3. If you choose to transform (move / rotate / scale!?) this link from
its correct location, that gets recorded as a 4x4 transformation matrix.
Note: I haven't implemented this properly yet.
Tests all pass, with a minor modification to the new behaviour that
false origin mode now won't affect the location it ends up in, only the
generation of the cache.
* Remove arbitrary convention around display name
Not needed anymore now that A/M/D is a detail and not significant on
actual coordinates, and also that the UUID is no longer needed.
* Simplify implementation of loading linked models when opening an IFC
* Move link matrix calculation from operator to tool for reuse
* Implement editing link location and calculation of transformation matrix
I changed my mind on the is_locked thing, since it isn't clear to the
user that locking need to be done to save changes.
* Remove old is_locked, prop update callback no longer needed (dedicated operator instead), remove old calculation code
* Simplify code related to placed_as_per_georef
* For now, simple skip for duplicate / delete
IMO duplicate / delete / move a link are very rare and explicit
operations.
* Update tests
* Remove host_model coordinate data as cache is no longer host model dependent
* Move icons outside list because there are too many
* Minor tweaks
