3D curves

[Bastien]

Hi,
I need help on creating 3d curves using two dimensional curves - Any suggestions would be really appreciated.
Thanks

Hi,
Try to avoid using 2 projection curve and instead try to extrude a surface from a plane as you normally. Then Extrude another surface from an adjacent plane. Where they meet creates an intersection. This is much easier to visualize and allows a trail for others to follow.
Cheers!
