Drawing Compare
Drawing Compare is an easy to use utility which allows you to compare two drawings and find the differences between them. You can use 2CD, DWG, TCW, and BMP files.
The process is simple, just load two drawings and press the Compare button. The Vector drawing files are converted to a raster image map and pixel testing detects changes between the two images.
