JTB Word's DWG Columns for Explorer has been updated to version 3.1.
DWG Created By, DWG id, DWG Reg and DWG Build are new columns in DWG Columns.
DWG Created By (can for example show AutoCAD 2017 or Inventor 2017), DWG id (for example ACAD0001409 making it possible to see difference between a drawing created in AutoCAD or an AutoCAD vertical like AutoCAD Architecture. ODA can show for a DWG created with the Open Design Alliance API), DWG Reg (Version in registry, for example 210 that stands for R21.0) and DWG Build (AutoCAD build number, for example N5200x64).
If you want to see the DWG and DXF properties and metadata in Explorer columns please give the trial a try. No need to have AutoCAD or other CAD programs installed for this to work. After the trial has expired you can still use it to show the DWG version information as long as you like.
If you are also a Revit user our RVT Columns shows the Revit version and Revit build for RTE, RVT, RFA and RFT files.
