You can define the boundary by selecting a single closed loop, one outer and one or more inner loops, multiple individual loops, or multiple intersecting curves, edges, or loops. Make sure that each loop intersects the ply boundary.
5. To invert the selection, use Flip Side. The highlighted area defines a new boundary for the ply.

OK.Examples—Trim by Contour
Some examples of valid trimming are as follows:
• The trimming contour is a closed chain that intersects the ply boundary.
◦ A—Original ply boundary
◦ B—Trimming contour
◦ C—New ply boundary without applying Flip Side
◦ D—New ply boundary after applying Flip Side
• The trimming contour is between the outer and inner loops of the ply boundary.
