Extrude Geometry
Extrude surfaces, nodes, or lines along their normal direction, a vector, or another line.
A extrude preview for FE geometry solids is not supported at this time.
Auto-Trim
Use the auto-trim option in the microdialog when extruding nodes and lines.
While extruding lines or nodes, if a continuous surface or mesh is intersected and this option is ON, the newly created surfaces are trimmed at the intersection. The auto-trim option works for both geometry intersecting geometry and mesh. It also works for FE topology intersecting FE topology.
