Export .dwg curved object

Hello,
I ask for your help.
What are the export settings in dwg so that a sphere, or any corbel object, does not become a mirror ball, when importing into 3ds max?

Best regards
Denis

Use SAT file to exchange Solids objects between Software. but as you fit into Autodesk products they have they own import and export options. 3DSmax can read DWG, DXF as well other formats…

Yes I will prefer to stay in dwg.
But I don’t understand why exporting to .sat or .fbx has mesh options, I can’t find them for dwg.

I found ! When saving or exporting, all you have to do is click on option,
then in the export diagram dialog box, “modify the diagrams”
Surface> mesh
Mesh> mesh
Record.
The mesh option appears with less or more polygon
