Although it is a very cool trick, I feel this essentially duplicates the
UI in two spots, and is an outlier in UX. I'd prefer for all IFC data
and relationships to be in one location only (the panels). I think there
are a better unified solutions (e.g. favourite bookmark panels) for
quick access for things like this.
To be consistent with all other settings, I've moved the visibility
config UI from inline into the add-on settings. This restores the
previous tab layout and no longer needs the "settings" icons to be
there. This also removes the need for a "enable UI config" checkbox.
Most of the code previously had dedicated operators to toggle booleans.
This has been removed. This new approach also means helpers aren't
needed.
Previously calculation of visibility was done on every draw (3x 10tabs x
10 collection items). The data class is intended to calculate UI data
once only which is more efficient. This also removes all helper calls
from the UI.
When assigning a container to an aggregated element, automatically promote
the operation to the root aggregate and move all nested parts to the
container's collection in the Blender outliner.
Changes:
- AssignContainer now traverses the aggregate hierarchy to find the root
aggregate when a user selects any nested part
- All parts and sub-aggregates are moved to the container's collection in
the outliner while preserving IFC aggregate relationships
- Parts remain aggregated in IFC (not directly contained), only their
Blender collection membership changes
- RefreshLinkedAggregate now also moves all parts to the correct container
collection when restoring original data
This provides a more intuitive UX - users can select any part and the entire
assembly moves together, properly organized under the spatial container.
Fixes the previous behavior where:
- Aggregated elements were skipped with a warning
- Parts weren't organized under the container in the outliner
- Aggregate nesting was broken after container assignment
- Auto-include all parts when duplicating aggregates
- Preserve nested aggregate relationships during duplication
- Select all duplicated objects for immediate moving
- Add dual-rotation support for AXIS3 slabs (IFC angle + object rotation)
- Fix profile editing to display horizontal projection for tilted slabs
- Fix AXIS2 layer slicing to use local extrusion direction for walls
- Fix ChangeExtrusionDepth to refresh geometry after depth changes
- Remove rotation lock on slabs to allow free rotation
- Fix undefined variable bug in add_slab_representation.py
This commit introduces a new BBIM_MaterialLayer property set to persist custom
material layer offset settings in IFC files, along with significant UI improvements
for material editing.
Features Added:
- New BBIM_MaterialLayer pset with properties:
- UseCustomOffset (bool): Toggle for custom offset
- CustomOffset (float): Offset value in SI units
- CustomWallReference (str): Wall reference point (EXTERIOR/CENTER/INTERIOR)
- CustomSlabReference (str): Slab reference point (TOP/MIDDLE/BOTTOM)
Tool Updates (tool.py):
- Added save_custom_offset_to_pset(): Saves custom offset from UI props to pset
- Added load_custom_offset_from_pset(): Loads custom offset from pset to UI props
- Updated get_material_layer_custom_offset(): Reads from pset when props unavailable
Operator Updates (operator.py):
- EnableEditingAssignedMaterial: Loads custom offset from pset on edit start
- EditAssignedMaterial: Saves custom offset to pset on edit completion
- Fixed KeyError for CardinalPoint in material constituent sets
Data Layer (data.py):
- Added bbim_material_layer_pset() to ObjectMaterialData for caching pset data
- Improves performance by avoiding repeated IFC queries during UI drawing
UI Improvements (ui.py):
- Added custom offset display in both editable and read-only material UIs
- Added OffsetFromReferenceLine display in read-only UI
- Implemented dynamic headers based on material type (Layers/Profiles/Constituents)
- Improved visual hierarchy with consistent boxing and indentation
- Aligned editable and read-only UI layouts for consistency
- Fixed layer set boundary labels (Top/Bottom for slabs, Interior/Exterior for walls)
- Reorganized "Add Material" section into material layers box
Bug Fixes:
- Fixed format_distance() to correctly handle negative imperial values
(e.g., -0.5' now displays as "-0' - 6"" instead of "0' - -6"")
This allows users to set custom material layer offsets that persist in the IFC
file and remain available across sessions, with clear visual feedback in both
editing and viewing modes.
