FreeCad, Blender, and SweetHome3D
We are using FreeCAD, Blender BIM, and SweetHome3D to take advantage of each tool in an architecture workflow. FreeCAD is good for technical design and part trees that can be exported automatically into Bills of Materials. Blender has BIM functionality for export in a universally readable open source architecture format. And SweetHome is great for ease of use and visualization, for both concept and technically-correct design.

This means that if we can interoperate seamlessly between the 3 open source tools, we can establish a robust, scalable, open source and collaborative workflow.

I observed that direct export from SweetHome3D to FreeCAD results in objects 10-20x smaller - see Google Presentation page at https://wiki.opensourceecology.org/wiki/FreeC..._Blender_Interoperability. So it is useful to use Blender for scaling the mesh file, then importing to FreeCAD, and turning back into a solid . Blender is good at scaling through its properties dialog, which allow numerical input. Does anyone else use SweetHome3D exports in FreeCAD, and know the correct scaling factor?
