- 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.
When appending a wall type and a slab type in turn, if their material
layer sets have the same name then the slab type would have a wall
construction. Now the material sets are compared before reusing an
existing material set.
