Cotty:
Never mind my last question, i found out what i`m did wrong the whole time...
I installed curvizard and select all contours 1 by 1 and using the make curve weld option.
and your right.. the script was telling me also to fix some problems.
After that there was no problem selection those lines(curves) and make the wing.
this will keep me going for a while.
Thanx all.
