How do you import Autocad file 3d into Solidworks?
File, open, search for file type in dropdown.
Check import setting on the open dialog.
Once you pick file type and the file, click option.
After you click open, you should have more options.
Don't know if 3DInterconnection helps.
I assume that you must have some problem with opening the dwg file and therefore there might be an issue with the file.
As indicated in previous response - I would first turn off 3D Interconnect.
Can you Attach it here.
Additionally; Autocad version must be same year or older than SW version.
I think it's a different problem. I don't know about the latest versions but the older ones did not import/export AutoCad 3D files, only 2D. I think it's still similar. If that's the case, you need to use a different conversion program, e.g. Rhino or FormZ. You can download a 30 day trial version and convert 3D DWG/DXF to STEP or IGES..Once you could use DraftSight for this purpose, but now.
Once you could use DraftSight for this purpose, but now DS depriving us of the free version of DraftSight has significantly reduced SolidWorks' collaboration with other programs. 3D DWG files are commonly used. Somehow nobody raises this topic in .discussions about DraftSight.
SWX 2020 offers the import of 3D models in DWG files ... the older versions not.
