DbView for AutoCAD 2007
DbView is a tool when loaded into AutoCAD used to look into your DWG file and spot problems with the underlying file database.
Please be careful in using it as it can edit the DWG and also corrupt them if you are not aware of what you are doing. The code for this tool is included in the free ObjectARX SDK from http://www.autodesk.com/objectarx.
