BIM Authoring alternatives comparison
| Tool | Verdict | Composite | Price signal | Agent access | Key formats |
|---|---|---|---|---|---|
| BlenderBIM (Bonsai) Fully free, native-IFC, and open source with a full Python scripting API and an active community MCP server for AI-agent control, but the Blender + BIM combination carries a steep learning curve. | Worth it | 4.6 | Free tier + from $0 | API | IFC2X3, IFC4, IFC4X3 |
| Archicad C4 5/5 reflects broad open-format coverage across IFC, DWG, DXF, DGN, BCF, SKP, STL, FBX, and PDF, C2 3/5 reflects the Archicad API plus C++ and Python scripting, and firm-size fit is solo to small-team. | Worth it | 4.2 | Subscription | API | IFC, IFC 2x3, IFC 4, ifcZIP |
