Which property cannot be changed from the Extrude PropertyManager after an extruded feature has been created?

When an extruded feature is created in SolidWorks, the Extrude PropertyManager enables modifications to certain parameters of that feature. However, the shape of the sketch profile cannot be altered from this PropertyManager once the extrusion is complete.

The sketch profile defines the geometry being extruded, such as its contours and features. While you can modify the extrusion’s direction, length, and width through the PropertyManager, changing the sketch itself requires editing the original sketch. This encapsulates the essential reason why the shape of the sketch profile is fixed post-extrusion.

Modifying the sketch would necessitate going back to the sketch in the Feature Manager, where you could then make changes to the profile before re-extruding it. Thus, the limitation on changing the sketch shape highlights the difference between altering parameters of the extruded feature and the fundamental geometry of the initial sketch itself.
