While modeling parts or assemblies in SolidWorks 2008 theedge lines occasionally become dashed. The only way to fix theappearance is to save the part/assembly and reload it. This happensfor sheet metal and extruded parts. It seems to happen whilerotating the model using the middle mouse button, but it doesn'tnecessarily happen every time.

Has anyone had this occur? I can work around it but it's prettyannoying to constantly have to save and reload my parts. I'veincluded a picture showing what a part normally looks like and whatit looks like after the lines become dashed.SolidworksGeneral
