Just as the title says when I open an assembly sometimes the entire assembly is engulfed in a huge sphere of lines that resembles a tumbleweed for lack of a better way to describe it. I then close out of solidworks and reopen the file with no problems. Another issue that may be related to this is sometimes when i open a part or assemblies part of the part or pieces of the assembly are missing. The part is there because i can see the shadow and a few ultra thin lines of the part.
I am lead to believe this may be a graphic card issue?
