About Skirt Surfaces
A skirt surface is a type of parting surface that you can create automatically by selecting a curve, such as a silhouette curve, that lies on the reference model. Using the tools on the Parting Surface tab, you can create a skirt surface by performing one or more of the following operations:
• Use the Extend Curve tool to control the outward extension of curve segments to the boundaries of the workpiece or die block, mold or die volume, or a mold or die component.
• Use the Fill Loops tool to fill closed loops that lie on a selected surface while controlling the offset.
