BIM & Architecture
Open-source tools for Building Information Modeling, architectural design, and construction coordination. Focus on IFC-based workflows, parametric building modeling, and interoperability.
Tools we test
| Tool | Type | Strengths | Status |
|---|---|---|---|
| FreeCAD (Arch/BIM workbenches) | Parametric BIM | IFC import/export, parametric objects, Python API | Active |
| IfcOpenShell | IFC toolkit | Python/C++ library, geometry extraction, validation | Active |
| BlenderBIM | Authoring platform | Native IFC, full BIM workflow in Blender | Active |
| LibreCAD | 2D drafting | DWG/DXF, lightweight, cross-platform | Maintenance |
| OpenSCAD | Script-based 3D | Parametric, reproducible, version-control friendly | Active |
Test categories
- IFC round-trip — Export → import fidelity across tools
- Clash detection — Automated coordination workflows
- Quantity takeoff — Schedule generation from model
- Parametric modeling — Wall, slab, window, door objects with constraints
- Drawing production — Plans, sections, elevations from model
