I am new to the Apex, so please bear with me. Once a sketch of a part is created and exited out from, how can this sketch be modified? When using the "Edit Sketch" tool, I am not able to modify the original sketch of a part.
The best way to do this in Apex currently is to use the Project tool to project the face or edge to the current sketch. Then you can use the sketching tools to edit the sketch. You still won't be modifying the original sketch though.
