I am struggling to integrate some of AutoCAD's vertical intelligent platforms (like AutoCAD MEP and Plant 3D) with Revit. It seems Revit is (barely) able to bring in the geometry and all the intelligence is left out. Is there somewhere in the API that I can customize the DWG importer to add support for certain pieces of information that I need to come through? Is there a configuration somewhere that I'm missing?
I found out that the Revit IFC exporter source code is available: http://sourceforge.net/projects/ifcexporter/
Is the Revit DWG or IFC importer available?
Also, in the Revit API I've found: DWGImportOptions but this does not seem to support what I'm looking for.
