Sketched Hole Requirements
To create Sketched holes, you must either select an existing sketch profile (sketched section) or create a new sketched section in Sketcher.
The sketched section must:
Contain geometric entities.
Be a closed loop with no intersecting entities.
Contain a vertical axis of revolution (you must sketch a centerline).
Have all entities on one side of the axis of revolution (centerline) with at least one entity normal to the axis of revolution.
