Hi @joshua.holzbach,

I see that you are visiting as a new member to the AutoCAD forum. Welcome to the Autodesk Community!

This error might show up when borrowing a network license. Do you think that might be the case? if so, this article suggests modifying a Group Policy setting  that can cause this problem.

If you are not using a borrowed license, can you describe what you were doing in AutoCAD when this happened? does it now happen on all drawings or just unique ones?

I don't think that's the problem.  The issue seems to happen when the user is trying to display a drawing as a wire frame.

HI @joshua.holzbach,

Thanks for the additional information.  It sounds like this issue is graphics related.  Try disabling hardware acceleration in the GRAPHICSCONFIG window.  Then, see if there is a more current driver for the graphics card.

The graphics card driver didn't have updates available, but the user had discovered that the file size was bigger then he expected.  It sounds like when he copied a portion of the drawing it worked without an error.
