Software Companions - PDF, DWF, PLT and TIFF Viewing and Conversion Software

Compare drawings and documents

Compare files using ViewCompanion

Comparing drawings manually can be tedious work. There is no longer a need to spend time trying to find differences between file revisions, use ViewCompanion instead to instantly show you the differences.

The compare feature in ViewCompanion is very easy to use, just load the first file, this could be the most recent revision, and then select a file containing an older revision you want to compare with.
After both files are loaded, ViewCompanion will display all information that is equal in both files as black. Information that has been deleted will be displayed as red color, and new additions are displayed using blue color. The colors used for compare may be easily changed if should you prefer to do that.
Multipage documents can be compared page by page.


File compare is available in all ViewCompanion editions, but the list of supported formats differs, please check below for more information.
