Extract the duplicate-aware relationship-walk + restoration logic
(get_decomposition_relationships, get_connection_relationships,
get_port_connection_relationships, recreate_decompositions,
recreate_connections, recreate_port_connections, consume_warnings)
out of tool.Root into its own service.
tool.Root's responsibility is identity and addressing of IFC roots;
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.

Adds:
* direction_from_port_pair(port_a, port_b) — derive the connect_port
direction kwarg from each port's FlowDirection (NOTDEFINED for
non-canonical pairs). Centralises a pattern that callers were
inlining inconsistently.
* tool.System.walk_connected_mep_elements — BFS over connected MEP
flow elements via IfcRelConnectsPorts.
* tool.System.get_port_world_position — port placement → world-space
Vector, used by the MEP path decorator.
* tool.System._build_decoration_data — cached decoration metadata
for the MEP system-path overlay.
Plus a get_port_relating_element return-type tightening (Union with
None) and a partial-init cycle workaround on bim.module.system.data
imports (now function-local — top-level import triggered the cycle
through tool.Ifc.Operator).

Top-level array-domain service extracted out of tool.Blender.Modifier.Array.
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 relocation eliminates the inline
duplication and gives Bonsai callers a single import surface.

Bpy-permitted wall reads — get_axis_local_extent, get_length_and_height,
get_x_angle, get_path_connection_location, walk_connected_walls — used
by gizmo lambdas that need wall dimensions and join topology without
the side effect of loading the wall's draft BIMWallProperties (the
loader mutates PropertyGroup state and would clobber the wall's own
gizmo state when both the wall and a hosted filling are selected).
All reads go through ifcopenshell.util.representation / .util.element
so the IFC graph stays the source of truth. tool.Wall consumes
core.model's PARALLEL_DOT_THRESHOLD + collinearity helpers (no inline
magic numbers).

Declares the bpy-free contract for tool services landing in subsequent
commits — tool.Wall, tool.Array, tool.System, tool.Duplicate (extracted
from tool.Root), tool.Parametric, plus minor additions on existing
interfaces (tool.Spatial.get_host_element / get_host_wall,
tool.Geometry.has_axis_representation / has_material_styles,
tool.Surveyor.get_z_rotation / set_z_rotation).
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).

core/model.py gains:
* Three calibrated dot-product / distance thresholds — PARALLEL_DOT_THRESHOLD
(~2° from parallel, cos(2°) ≈ 0.9994), COLLINEAR_LINE_TOLERANCE (50mm
perpendicular distance for two parallel wall axes to share a line),
BASELINE_OFFSET_TOLERANCE — replacing inline magic numbers that the
wall-join classifier, fillet-state machine, and gizmo preview decorator
all read from.
* Pure wall-join geometry helpers (project_axis_intersection,
are_axes_collinear, classify_wall_join_state, wall_join_preview_lines,
resolve_extend_walls_target, extrusion_depth_from_vertical_height,
length_and_height_from_extrusion). They take primitive tuples + floats,
no bpy, no ifcopenshell — testable in the core lane.
core/product.py is new — pure-Python aggregate-walk helpers (resolve_host_
of_product, collect_decomposed_products) that downstream tool/spatial and
tool/aggregate consumers can call without importing ifcopenshell at module
load.

add_railing_representation now factors into two parts:
* compute_wall_mounted_handrail_geometry returns a pure-geometry
WallMountedHandrailGeometry dataclass (handrail polyline + support
list + terminal caps), no IFC mutation.
* add_railing_representation wraps that dataclass into an
IfcShapeRepresentation as before.
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,

Use add_layout_hotkey_operator for draw_regen_operations so the Regen

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

PowerShell and some wrapper scripts on Windows occasionally strip

Auto-commit stays as the safety net; the count now suffixes the

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.

Three small post-landing cleanups against the parametric framework commit:
* core/model.py had `are_axes_collinear` and `closest_endpoint_midpoint`
each defined twice — Python silently kept the second copy, the first
was dead code. 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.

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.

Port gizmos-8088's railing gizmo block to v0.8.0:

The check `len(bytedata) == n * 2` was wrong: float64 is 8 bytes per

GizmoWallEdition.position_gizmos used props.anchor_x / props.length
for the in-range check (split icon visibility) and perpendicular
gizmo placement. Those props mirror IFC and are re-primed by
_maybe_resync_wall_props_from_ifc — any operator path that skips
the re-sync leaves the perpendicular gizmo clamped to the previous
wall extent, so the icon parks at the old wall end instead of the
cursor's orthogonal projection. Visible after a wall mutation as
the perpendicular icon landing way off the cursor in top-down view.
Switch to the mesh bbox along local X. recreate_wall rebuilds the
mesh to match the current IFC body on every wall mutation, so
bound_box is authoritative without an explicit props sync.

MEP elements imported as tessellation / brep (no IfcExtrudedAreaSolid
or IfcSweptDiskSolid in their body representation) can't be
parametrically edited — the gizmos offer affordances the geometry
kernel has no path to honour. tool.System.has_parametric_body
inspects the Model/Body/MODEL_VIEW representation and returns True
only when at least one item resolves to one of the two
profile-sweep primitives.
The gate is wired into:
- GizmoMEPActions.is_eligible_object (the action icon group)
- _active_is_flow_segment / _active_is_bend_fitting visibility
predicates the icon row consults per-icon
- GizmoPipeSegmentEdition / GizmoDuctSegmentEdition is_element_type
tool.Parametric.is_pipe_segment / is_duct_segment stay IFC-class-only
so their truth-table contract test keeps reading a single concern.

re-uses within a generation and rebuilds on generation bump.
- test_mep_distribution_fit_smoke.py: bim.fit_flow_segments

Two small refactors:
- apply_transform_modal_draw_gate(group, context) replaces the
three-line _is_transform_modal_active + _hide_all_non_modal_gizmos
pair that BillboardingGizmoGroupMixin, BaseParametricGizmoGroup
and BaseSchematicGizmoGroup all repeat in draw_prepare.
- decorator.py renames _stroke_lines_alpha to a public-scope
draw_polyline_segments and drops the no-longer-private companion
docstring reference; the function is now usable by sibling
decorators that draw polyline overlays.
Plus a few one-liner tweaks in tool/model.py and opening.py

Two hot paths the gizmo polls fire every viewport event memoise
their result against tool.Parametric.get_geom_generation():
- tool.Blender.Modifier.any_selected_array_child caches the
per-selection scan against the selection identity-set + the
IFC generation token so a stable selection during a drag
doesn't re-walk every selected object's BBIM_Array pset every
frame.
- bim/module/model/wall.py grows a pair-predicate + connection
cache that the wall topology gizmos hit; both keyed on
(pair_uids, predicate_kind, generation) so a wall split or
axis edit invalidates correctly via the generation bump.
Behavioural contract is unchanged — stale entries are evicted
on generation bump; cache miss returns the same value the
un-cached path returned.

bim/module/model/conftest.py exposes the autouse _require_real_bpy

test was repeating.
Existing test files in the directory drop their local copies of

Three concerns bundled by file boundary (all in mep.py):
- Extract bend preview operators + GizmoBendPreview into a focused
mep_bend_preview.py module; preview_base.py grows the shared helper
set both bend and other previews now consume; classes tuple in
model/__init__.py updated to register the new module.
- Surface ERROR reports on five silent CANCELLED returns in
MEPUnjoinAtPort / MEPRemoveTerminalFitting / MEPUnjoinPair so a
degenerate IFC file ("fitting has no Blender object", "connected
port leads nowhere") shows up in the popup instead of looking like
a no-op.
- DRY: _resolve_active_mep_segment + _require_port_state factor the
segment-id-or-active-object resolve + port-state guard out of every
port operator's prologue; _wire_anchored_icon_targets pulls the
GizmoMEPActions setup() body into an exercise-without-MRO helper so
the wiring-contract tests can hit it without instantiating the
GizmoGroup.

The opening preview's outline used a single-batch two-pass scheme that
dimmed the occluded back pass via alpha=0.25. 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 "<uid>_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.
