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.
Fixes typo introduced in b4740b6 where `element in MATERIAL_SETS` should
have been `element.is_a() in MATERIAL_SETS`. This resulted in
deduplication of layersets, but not of the layers themselves.
Enable multiple CSS files in stylesheet_path using comma separation.
Files are loaded in order with natural CSS cascading behavior.
Example: "base.css, overrides.css"
"In some versions of Python, instances of classes may have an
__annotations__ attribute. However, this is not supported functionality.
If you need the annotations of an instance, you can use type() to access
its class" https://docs.python.org/3/howto/annotations.html
When editing representation items for elements with IfcMaterialLayerSetUsage
(LAYER2/LAYER3), the depth attribute is now hidden from the UI as it should
not be modified at the item level for these parametric elements.
The check is performed by accessing the parent element through the
representation_obj property in geometry props and checking its material
usage type.
The copy_node_graph() method checks for a "window" key in the context
override, but get_shader_editor_context() wasn't providing it. This
caused the function to return early, preventing external styles from
loading.
Updated get_shader_editor_context() to include the window when the
screen differs from the current context, following the same pattern
used in get_viewport_context().
Changed tolerance from 1e-5 to 1e-4 to account for floating-point errors
introduced by matrix transformations. Fixes section annotations being
incorrectly excluded from drawings when they should be visible.
Moves IfcSpace hiding from collection assignment to after scene
addition, allowing hide_set() to work properly once objects are
in the view layer. Fixes RuntimeError during IFC import.
When duplicating elements, skip assign_body_styles if the element's
constituent materials already have style representations. This prevents
creating redundant IfcStyledItem entities on the geometry when styles
should be inherited from the material definition.
