Consolidation
THICK_LINE_HELPERS_WGSL — a macro that both AXIS_WGSL and SECTION_WGSL
prefix via adjacent string-literal pasting — holds:
- VsOut: clip_pos + rgba colour + side_t for AA
- thick_line_clip(p_start, p_end, t, side, viewport, line_width):
the screen-space quad expansion with consistent perpendicular so
the quad never collapses into a bowtie
- fs_main: |side_t| + fwidth() coverage smoothstep — analytical
1-pixel AA regardless of MSAA
Each gizmo shader now only declares its uniform struct + a 10-line
vertex shader. C++ side gains thickLineVertexLayout(attribs[5]) so
both call sites set up the 5-attribute layout in one call instead of
20+ lines each. Net diff is -28 lines on this commit and roughly -60
relative to the unconsolidated section commit; the next thick-line
gizmo (measure tool, selection outline, …) starts from ~30 lines of
WGSL + a vertex buffer.
Bonsai decorator palette
All overlay colours now come from src/bonsai/bonsai/bim/ui.py's
decorator_color_* defaults so they match Bonsai's Blender add-on:
decorator_color_error = (1.000, 0.200, 0.322) red → +X axis, section gizmo
decorator_color_selected = (0.545, 0.863, 0.000) green → +Y axis
decorator_color_special = (0.157, 0.565, 1.000) blue → +Z axis
Section gizmo polish
- Entire gizmo (quad outline + arrow shaft + arrow head) goes red.
GL's white quad + yellow arrow disappeared against light surfaces;
one saturated red reads against any background and identifies the
geometry as a tool overlay.
- Line width bumped to 5 logical px and the per-vertex tint dropped
to (1, 1, 1, 1) so the tint multiplier stays available for a future
"selected" state without changing the base colour.

IfcOpenShell
IfcOpenShell is an open source (LGPL) software library for working with Industry Foundation Classes (IFC). Complete parsing support is provided for IFC2x3 TC1, IFC4 Add2 TC1, IFC4x1, IFC4x2, and IFC4x3 Add2. Extensive geometric support is implemented for the IFC releases IFC2x3 TC1 and IFC4 Add2 TC1. Extending with support for arbitrary IFC schemas is possible at compile-time when using C++ and at run-time when using Python.
In addition to a C++ and Python API, IfcOpenShell comes with an ecosystem of tools, notably including IfcConvert (an application to convert IFC models to other formats), Bonsai (an add-on to Blender providing a graphical IFC authoring platform), and many other libraries, CLI apps, and more. Support is also provided for auxiliary standards such as BCF and IDS.
