We are switching to Creo 3 and have noticed that the boundary lines from detail views are disappearing. Please see the pictures below. They show in Creo 2 but when opened in Creo 3 the boundary does not show up. Both versions are shown when printed.
maybe it is graphical problem. Try to add graphics win32_gdi option at the end of config.pro file and open the drawing in Creo 3.0, again.
I have tried this drawing on other machines and I can not duplicate the issue. I will post again if I can figure out how to duplicate the issue. For now consider this closed. Thank you for your responses.
