I've been working on an assembly for a couple of weeks now and this morning it decides to disappear.
When I open the assembly file there is no model displayed while it loads all of the parts. The design tree populates and it looks like everything is there.
Rotating and zooming shows glimpes of the model. Some it will stay on the screen after I'm done moving the mouse. But zoom or rotate again and it disappears.
I can click on the model and edges of a part will show up. I can select with a window and parts are highlighted in the design tree. Sometimes selecting parts in a window will show the parts on the screen.
Now I'm sure your first thought will be is the display driver updated. But I don't think that's the problem.
I've been using this setup for most the year.
I've been working on this assembly for quite a while with no issues.
I've opened the assembly on another computer and the assembly is never shown. No glimpes while rotating or zooming but I can randomly select parts.
My computers are
HP 8540W, NVIDIA FX 880M
Windows 7 x64
4606mb Total available graphics...
1024mb Dedicated video memory
HP 8530W, NVIDIA FX 770M
Windows XP 32 Bit
512mb video memory
Any ideas what I can do?
