Hi Michael,
unfortunateley I continued to work on the project, and thats why I do not have that particular version anymore.
I sort of restarteed and have it fixed now. I think, it was messed up firstly because the two rails which the
surface was made of had very different amount of control points to begin with. Then the shap I wanted to flow was
also created in a sort of akward way. These two less than ideal circumstances have been (i am sure) responsible
for the strange shape, because after I adressed both issues, it worked quite niceley!
Nontheless,
Thank you for your great help!
Regards
Heiner
