I have Sketchup Pro 2014. I am trying to export my model to 3ds max 2010. The problem is that the smoothing groups don't import (no big deal) but I can't get the smoothing groups under the poly editor to take in 3ds Max, not even the turbosmooth modifier will work. Several google searches later I am still at a loss for what is going on.

I have tried exporting 3ds, dwg, and dxf formats so far.

Is this is common problem that has an easy solution? I hope!

Thanks for your help.
