Graphics Issue - objects not printing correctly

[corcad]

Hello All,

When I print certain drawings using the "legacy hidden" shade plot setting (2011 only, 2010 doesn't seem to do this nearly as much) I get very strange results. Most objects hide correctly but a few random pipes and pipe fittings will look as if they are corrupted. I've tried re-creating all objects from scratch using blank templates I still end up with these results. I have attached an image to illustrate what I am talking about. I have also attached an image of the same drawing being printed from 2010. You'll notice that there is still some corruption and lines are not hiding correctly, but not in the same way as in 2011.

I've been having this issue intermittently and randomly. It is always reproduced on other workstations which are using identical hardware:

Win 7 64-bit

Intel Core i7 920 @ 2.67GHz

ATI FireGL V7600 (have used current drivers as well as Autodesk recommended drivers)

RAM 8.00 GB

Any ideas? Is it time to trade out those V7600 video cards?

Thanks for the help,

Matthew Corbin
