Hello everyone! I am new to this website and am seeking some advice..Here is my problem: AutoCAD program crashes frequently when I am opening dwg extension file. Error message: Unexplained file size increase.Do you have any suggestions how to work around it? Any suggestions ideas would be great.

Could possibly be DGN related linetypes.  Do you trade drawings with other companies?  What steps have you taken so far to troubleshoot the problem?
