Yep, the problem was unwelded vertices, thx again!

Thanks guys, I didn't expect replies so soon! Buying more software is not an option for me, but I will definitely try that welding trick!

Hi people,

it seems to me that regular editing tools fail to work properly on models imported from SketchUp. It looks like polygon normals are not stored correctly since tools like chamfer and mesh smooth don't work as expected. Does anyone know how to workaround this problem? Do I have to watch for something while editing in SU? Is there a smarter export plugin perhaps? SU sometimes could be better for modeling certain things than MAX, but I can hardly add details later after import.

Thanks for any answers,

K
