I have a very irritating problem and wonder if anyone else has experienced the same. After working for a short time in 3D, my object snaps dont actually connect to any visible corners or points on the item I have chosen to edit or move. The triangle or square appears further from the point I select. The frustrating thing is there is nothing behind the object I am trying to work with and it appears to be attaching to some invisible point. The only work around is to close down the program and restart. After only a few transactions, the problem starts again. I have tried to reconfigure the 3DCONFIG but is not the answer. The graphics card I am using is a ATI FirePro V5800 (Fire GL). I have checked the system and found it is using the latest driver.

Have you tried to switch off the hardware acceleration within _3DCONFIG ==> manual tune?

Thank you for the tip but sadly, it did not sort the problem. I switched off the accelerator and rebooted but after about two minutes, it was back to its old tricks. I have a feeling it is something to do with the graphics card and the actual program. I have tried my database on a colleagues machine and although it happened there, it was not as bad as mine.
Thanks again Alfred

So with the same gc/driver you have the same issue on two workstation? I would then try to install an older driver (as you mentioned you have the current one installed). Locate a driver about a year old and try to install it .... or look to the >>>certified hardware<<< from the Autodesk-site and take the driver listed there.
Good luck, - alfred -
The symptoms you describe (works for a while then stops) don't sound like a graphics driver/setting/hardware issue to me, especially since a restart of the program (not Windows) fixes it.
Does this happen in all files, or just the one file?
Types of "3D" work you are performing in the file?
Is there a trigger you noticed, or is it just time?
The problem is with any file I work with. When I first log into the job, it works fine then after a while the tags are all over the place. There are no warnings, it just happens suddenly. What I have found is that if I open more than one job and switch to the other job then back, everything works properly again, for a while. I have even tried to change the mouse. I have not as yet tried changing to an older graphics driver as has been suggested previously but that is the final proceedure for me to try. Other than that I will just have to have more than one job open and keep switching or log out of Autocad then log back in.
Incidentally, my files are not all that big as I have referenced other equipment into my project. Bigger files that have been loaded, dont seem to have the same problem although I do have the odd situation where the system just locks up and I have to bring in task manager to switch it all off.
