Is it possible to export a 3d building model from auto cad 3d to arcgis for data management?
It depends on the geometry used to model the building information in AutoCAD. ArcGIS does a pretty good job of using 3D polylines and 3DFACES directly from AutoCAD files and or converting those CAD objects to MULTIPATCH features.
Yes but it may take some work to fine tune how you do this to get the data out in the best format.
first challenge is georefferencing. Then you may have to export as a dxf to simplify new more complicated objects in AutoCAD. Or just have to save the file in AutoCAD with the proxigraphics setting set to 1 to simplify the new advanced objects to GIS compatible. Once you have the file in GIS it is a matter of filtering out the objects that are not meaningful to your final goal.
I am in the middle of automating a BIM conversion from a CAD-like program. Best of luck.
