DWGintVer displays internal version information from DWG files - the source Autodesk® AutoCAD® release, its build number, language and vertical version (Autodesk® Mechanical, Autodesk® Civil 3D®, Autodesk® Electrical, Autodesk® Plant 3D, Autodesk® AutoCAD® LT, etc.).
You can display this information for the opened (and not yet saved) DWG file. Alternatively, you can use the DWGintVerCon console application to scan the whole drawing folder, including its subfolders and display version information of all DWG files. The results of this batch scanning can be also stored to a CSV file (for Excel). Run parameters:
DWGintVerCon <folderName> [<CsvFileName>]
