Kernel and Geometry Docs

Use this section for the BREP kernel, geometry data model, class APIs, topology tracking, and export behavior.

Start Here

• BREP Kernel Reference - source-level overview of src/BREP responsibilities.
• BREP Model and Classes - compact conceptual summary of the geometry model.
• BREP.js Export Map and Usage - what is publicly exported from BREP.js.

Core Classes

• Solid Developer Guide - workflow-oriented overview for Solid.
• Solid API Index - canonical per-method reference for Solid.
• Face API Index - canonical per-method reference for Face.
• Edge API Index - canonical per-method reference for Edge.
• BREP Class API Reference - hub for all kernel class method docs.

Kernel Topics

• Topological Face Naming and Triangle Ownership
• Radius Metadata for Extruded Sketches
• Cylindrical Face Radius Embedding
• Simplified Radial Dimensions
• Fillet Process
• File Formats: Import and Export
• C++ Solid Porting Notes

Example Pages

• BREP Booleans Demo
• BREP Primitives Demo
• BREP Transforms Demo
• BREP Export Demo

Suggested Reading Order

1. Read BREP Kernel Reference for structure
2. Open BREP Class API Reference for exact class behavior
3. Use the topic pages above for deeper geometry-specific behavior
