I have a question about machining a feature on a solid model without having to select the whole solid model. For example, I have drawn a cylinder that is 2.00 in. diameter and 1.00 in. tall with a .250 X 45 degree around the top edge. I cannot for the life of me figure out how to only select the chamfer to machine it, instead the whole solid is always selected. Can someone show me the right direction? Thank You for your time.
