TrustedDWG™ Drawing Files
DWG, DWT, and DWS files that are created with Autodesk applications and RealDWG™-based applications are trusted by Autodesk. When you open a TrustedDWG file, the following icon displays in the application status bar or the drawing status bar.
If the DWGCHECK system variable is set to On (1), an alert box is displayed if:
- The drawing file format is AutoCAD Release 14 or later and
- The drawing file was not saved by an Autodesk application or RealDWG-based application.
