I'm trying to import objects through 3ds max using dwg as format.
Unfortuately it fails to import proper UV coordinates and normal information.
The object ends up flat shaded and the UVs are all over the place.
Is this a limitation of the importer or the dwg format itself?
I saw some Revit families containing imported object with proper UVs, though no smooth shading either, I wonder how this were imported.
have tried to save in .sat file format and then import it into a Revit Family - as Mass Element?

Thank you very much for your reply.
I tried it now and unfortunately it yields the same result.
I dug a bit more into it and found out that the family I suspected having correctly imported UVs is made up of dxf imports.
As I know now, dwg and dxf both don't contain UV information, the UVs of that family were created on import by Revit I assume. At least that's what is happening if I import dxf.
I don't have Rhino or Sketchup for testing therefor I guess I'm out of options.
Unfortunately this is the Revit limitation. I can never get the map to display properly without the texture stretches and not coordinating properly. You either make it a plain simple color or model it as detail as possible. Here are sample what I get normally. Texture works fine if the texture is small like leather fabric. When you want to add pattern fabric, it failed miserably.
It doesn't fit correctly, but at least at looks like you have UVs on your model. How does it look like in a DCC Programm like 3ds Max? Is the UV layout the same?
Could you describe import workflow please?
Here is an example of how the imports look for me.
I have the same issue import DXF/DWG to Revit. Material will often won't display correctly. 3d Mesh usually have issue. If you want it to be successful, I would use 3d solid. Even with 3d solid, it sometimes won't translate the object correctly. These day I avoid doing that and built it straight within Revit. That mario was built within Revit. Post a sample and we can analysis.
Thanks! Modelling certain things in Revit is too complicated, time consuming and doesn't give me full control over the UVs anyway. Especially when thinking of objects that are only for visualisation and don't serve any other purpose in the Revit model.
