Hi guys,

sorry for my late answer, but i tried most time of last night to get a result with zsurf, but it was not satisfying.

@manz: wow ! How can you do this in such a short time ? You can give me the 3dm file ? No, just kidding... i have tried it for hours but i have to do some more practice....

I must work the hole day ( now lunchbreak ) so i soonest can get back to this thread tomorrow.

Thanks for your ideas,

Reiner
