About Curves in IDD
In IDD, you can create and modify curves. No parent-child relationship exists for curves created in IDD. However, you can create constraints on curve ends that limit their modification in the IDD environment after their creation.
You can create the following curves in IDD:
• UV-curves by projection
• UV-curves by the intersection of surfaces
• UV-curves through points on surfaces
• UV-curves isoline on surfaces
• Sketched curves
• 3D curves through points
