How does this compare with Revit? It seems wrong to me to compare it to SketchUp and blender, as they are not BIM, and just regular modeling software
Though before revit was bought by autodesk it was probably in a similar point (2d drawing was really poor).
I think the biggest open source success in related industries is still qGIS. I hope this can be replicated in the architectural CAD sector. If so though i think it will have to offer something else. FreeCAD is pushing the best BIM integration which is great. But if you talk to a lot of architects right now they are excited about Grasshopper and Dynamo visual programming which the attached says is yet to come in freecad. Heres hoping it turns out well. My view is that if it does this well and picks up for 2d drawing it could be a serious competitor
