What would cause this?
I have a ati v4800 card in the machine. running 2 23" dell's.
It is a model I got from a cd, I am a student so new to all this.
Looks like your computer is running too hot and melting the model.
Maybe use a material with a higher melting point.
Could be a graphics driver mismatch, or a non-Aero theme problem, or the graphics card could be failing.
Run the SolidWorks Rx tool to see what it finds.
If you are using Windows7 and you have Aero Themes disabled, you can see some strange things. SW2012 utilizes Areo Themes.
Nevertheless, it looks so cool!
When I run the troubleshoot program from microsoft it tells me "video card doesn't support required display settings"
Fixed needed latest driver for video card.
