Here's an odd situation. My lead engineer is unable to revolve a sketch if there are construction lines inside the sketch. I watched him create a simple rectangle and revolve it with no problem, but when he went back into the sketch and added a smaller rectangle out of construction lines inside the existing sketch, it would not revolve. He isn't getting an error message or anything at all. It just doesn't revolve. He can't pick to select the axis or anything. I tried it on my computer without a problem which makes me think there is a setting somewhere in the options?
