They discuss this here when comparing to 'the commercial alternatives we all know'. Key things they admit it is bad at are user friendliness and 2d output. Both are pretty essential for serious use in the architecture / construction industry. 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
