In SOLIDWORKS 2017 you can Extrude from any size planar face. You can create boss, cut, and surface extrudes from any size surface, face, or plane. The surface or face must be planar.
Previously the From > Surface/Face/Plane selection needed to encapsulate the entire sketch.
To extrude from any size planar face:
- In parts, click Extruded Boss/Base (Features toolbar) or Insert > Boss-Base > Extrude. This functionality is also available for Extruded Cut and Extruded Surface.
- In assemblies, click Insert > Assembly Feature > Cut > Extrude. Select a sketch. Under From, select Surface/Face/Plane, and select a planar surface or face, or a plane.
