Free app to read/check unique invisible watermark signature added through DWGsign

General Usage Instructions

The free DWGsign Reader checks any signatures (watermarks) previously to the current DWG document using the full commercial version of this add-on - DWGsign. Please note that the added watermark signature does not prove unmodified state of the original document (like digital signature does), it proves that a document is based on your original data. 

This application is compatible with the AutoCAD® 2015 and 2016 and 2017 families (32-/64-bit, any language version).
