Export in dwg as mesh/ solid

I AM TRYING TO EXPORT CILINDERS FOR EXAMPLE TO DWG, IT ALWAYS EXPORTS IT AS FACES INTO AUTOCAD, AND I WANT TO GET ONLY ONE POLYFACES MESH, I MEAN, ONE FOR ALL THE FACE OF THE CILINDER, NOT ONE FACE FOR EACH SEGMENT, AS SEEN IN PICTURE:

Hello,

This is not possible. As you may know, sketchup does not handle circles like autocad would do, but with a defined number of segments. Same for cylinders that are extruded circles.

After exporting them to dwg, You’ll end up with as many vertical lines as your base circle has

however, recent sketchup versions are able to export them as true circles in autocad, what you can do is extrude them in autocad once imported

I’m not sure what ONE POLYFACES MESH means, but try exporting from SU to .3ds and then importing the file into CAD. All the faces are exported together.

I would guess that is exporting only the faces and the other option is exporting the data for the edges and the faces
