Hi!
I am modeling the basic shape with a primitve than draw
curves on that surface and duplicate them.Then I rebulid them ,the problem is that when i rebuild them they are not touching where they intersect.I want to use these curves for boundry patches...how can i solve that problem.
The simplest solution that comes to mind, is insert knots at the intersections. You will have to zoom in real cose to the intersection of the two curves to be accurate. Then snap the two coresponding Edit Points togeather. Hope this helps.
Detatch the curves where they intersect before you rebuild them.
