Question
A
If you need to compare two DWG files a find their differences - changed, erased and added geometry - you can use the free application Autodesk Design Review (see Download).
This tool employs the DWF/DWFx drawing format and its function "Compare Sheets" allows to highlight in color all differences in the geometry of both drawings.
The workflow of generating DWF from a drawing and comparing two schemes from AutoCAD P&ID is described in a video available in the CAD Video section - see AutoCAD video #12
