BlenderBIM
A completely free and open source BIM authoring addon for Blender.
Overview
BlenderBIM is a free and open-source add-on for the popular 3D creation suite, Blender. It extends Blender's capabilities to support a native, data-rich BIM workflow based on the Industry Foundation Classes (IFC) standard. It allows users to create and document building projects entirely with open-source software, from modeling to scheduling and documentation, without relying on proprietary formats.
✨ Key Features
- Native IFC authoring (IFC2x3 and IFC4)
- Creation of walls, slabs, doors, windows, and other BIM objects
- BIM data management (attributes, properties, classifications)
- 2D drawing and documentation generation
- Costing and scheduling (4D/5D) capabilities
- Clash detection
- Integration with Blender's advanced modeling and rendering tools
🎯 Key Differentiators
- Completely free and open-source
- Native IFC workflow, not just import/export
- Leverages Blender's world-class modeling, rendering, and animation tools
Unique Value: Provides a complete, professional-grade BIM authoring environment for free, built on the robust IFC standard and leveraging the powerful creative toolset of Blender.
🎯 Use Cases (5)
✅ Best For
- Firms committed to a 100% open-source workflow
- Detailed authoring and manipulation of IFC data
- Combining BIM with high-quality rendering and animation for presentations
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Users unfamiliar with Blender's interface
- Large corporate environments requiring commercial support
- Projects where proprietary formats like RVT are required for deliverables
🏆 Alternatives
Unlike traditional BIM software that treats IFC as a secondary format for import/export, BlenderBIM uses IFC as its native, core data structure, ensuring a true openBIM workflow and eliminating data loss.
