Point Cloud disappears when rotating/zooming

[Ataloss]

I have a point cloud furnished by a supplier that I have use to create surfaces. Whenever I rotate the model, (or zoom or pan), the point cloud and most of the lines disappear, and the surfaces turn into blocks showing the real estate the surface takes up. When I finish rotating, the point cloud returns and the surfaces return to their proper display.

I know there's a setting somewhere that can change this so that the point cloud is always visible, and the surfaces don't change into blocks, but I can't for the life of me find it. I've gone through the Preferences/Visualization and Visualization Performance but couldn't find anything.

The computer is a Dell Precision 360 with dual 2.8ghz processors, 1 gig of ram and an NVidia Quadro FX1000 video card (128MB) running XP Pro. I remember having this problem with another computer running NT, but stumbled across the setting to fix it. That machine (our only other UG machine) was taken by IT a couple of days ago to be upgraded to XT so I can't look at that one to compare settings.

I don't normally use UG, so please forgive me if I'm missing something really basic. Any help or suggestions you can provide would be greatly appreciated or recommendations for a graphics card if you think that's what it is (I know Solidworks has features that only function on certain cards, I don't know about UG).

Thanks,
Bob

Preferences->Visualization performance... then choose the 'Large Model' tab and uncheck the 'Fixed Frame Rate' option. That should do the trick.

Go to Preferences -> Visualization Performance -> Large Model. Check the "Hide Objects" option

I was typing my post as cowski was replying. Just goes to show that there is usually more than one way to accomplish something with UG!
