Renamed PI and CC to TI and NI
Fixes handling of units (now works correctly with US and SI units)
Changed tests to use US feet units
Fixed documentation
- Add clear_layout_segments API to remove segments while preserving alignment ID
- Modify exit_pi_edit_mode to edit segments in-place instead of delete+recreate
- Fix curve visualization by using create_shape for segment vertices
- Fix evaluate_segment validation to handle negative-length curve segments
This prevents "Active alignment no longer exists" errors when editing PIs
and properly renders circular arcs regardless of turn direction.

- Fix modal operator to use absolute mouse coordinates converted to 3D
viewport region space, instead of event.mouse_region_x/y which are
relative to whichever region received the event
- Store 3D viewport area, region, and region_data references in invoke()
for consistent raycasting throughout modal operation
- Add coordinate transformation methods (blender_to_ifc_coordinates and
ifc_to_blender_coordinates) for projects with geospatial Blender offsets
- Transform alignment curve vertices from IFC global to Blender local
coordinates when has_blender_offset is enabled
- Add try/except for piecewise-step-size geometry setting in util.py

Add RuntimeError handling for IfcOpenShell versions that don't support
the piecewise-step-type setting in geometry generation.

- 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
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.
