You can modify the one-sided boundaries of surfaces in IDD by using most of the tools for curve modification.
• Modify shape (
Modify)—You can modify the shape of a one-sided edge by tweaking its control polygon or by modifying its interpolation points.
• Merge contiguous one-sided edges of the same surface (
Merge Curves)—You can merge two or more one-sided edges into a single edge.
• Replace contiguous one-sided edges of a surface (
Replace)—You can replace two or more one-sided edges with 3D or UV curves or a chain of one-sided edges or curves.
• Split a one-sided edge (
Split Curve)—You can split a one-sided edge into two by selecting a point on the curve.
• Move a vertex (
Move Vertex)—You can move a common vertex between two one-sided edges of the same surface.
