Can you make a small drawing of a simple part and upload both the drawing and the part that exhibits this behavior? I'm thinking it is something simple, like those lines are on a hidden layer or something.
1) Did you place it on a layer that is set to not print?
2) Does this do this with ALL broken out views, or just the ones on this drawing?
I wouldn't think the model edges would have been placed in a Layer that's set to not print, but it's possible. Do you have a Layer with that setting? Also, have you checked your settings when saving to pdf? See the first paragraph in #7 at Frequently Asked Forum Questions.
