I am trying to figure out how to show a model axis in a drawing. I need to pick up the center of a tapered hole, (a cone), from above and can't. The center mark feature doesn't work because the tapered holes break-out on non-planer surfaces on both sides of the part. I can easily add an axis to each hole in the model but they don't show up in the drawing and thus I can't pick them. Any suggestions?
