I have a drawing and assembly that were both imported from I-deas. The migration to NX created some problems on the drawing. Whenever I try to do anything to the section views - in this case I want to hide some extra geometry - I get the error message: "Exact (Pre-NX 8.5) Section View, 4-Section A-A, did not update." I also deleted the section view and then tried to re-create it and I get the same message. Even when I try to create any section view, the message appears. Does anyone have a solution? Thanks.
