There's a Blender addon under development for BIM called https://blenderbim.org/ they're looking for funding

Blender's user interface is fully scriptable in Python, which means you can really adapt to your personal workflows or that of the company

BlenderBIM accomplished a lot in about a year, but I guess we're all aware of what kind of monumental undertaking this is.
