Trim Solid

This command trims a solid model by either a closed polyline or station range along an alignment polyline. The resulting trimmed solid is saved to a new MDL file. This command is a way to carve out a subset solid.

For the closed polyline method, the polyline should be entirely inside the limits of the solid.

For the alignment method, the centerline polyline should be a 3D polyline that goes along the full length of the solid. This method applies to solids of tunnels. The program prompts for the starting and ending stations along the polyline. The solid is sliced at these stations and then combined with the original solid faces between these stations to create the new solid.
