A long while back, I posted about an OBJ Exporter for Revit by Jeremy Tammik. Looks like there is another way of doing this now, and it has been released for Revit 2014 and 2015. The purpose behind this addin is to allow easy import to Blender for rendering – but it could be used for many other things too.
