Hi Michael,

thanks a lot !

I somehow must have messed up on my way. I actually tried always to snap the end points of my curves on the respective other curves to make the surfaces closed and defined. That was where I tried to aim for in my initial question, since once I have a complex network set up, and skinned the thing, but choose to move one curve or curve point, I very likely loose the "watertightness" of the model. I never figured out how to keep all surface curves aligned at once, so it was a constant hopping around and checking if there are holes anywhere.

I´ll just download the no-save trial version and see if i can reproduce your advice.

Thanks again for the OBJ-files, I´ll check them in Cinema4D!

Michael
