Files created by Cadlib triggers the "student version" message in AutoCAD 2019

Hi I'm having problems with DWG-files generated with Cadlib when opening them in Autocad 2019. Dwg-files created or modified by CadLib in the AC1032 format will be flagged as being "saved with a Student Version of the product" when they are opened in Autocad 2019. The problem goes away if the file is saved in the AC1027 format (AutoCad 2013).

C# Code:

// Create an empty AC1032 DWG which will trigger the "student version" message in AutoCad 2019. var dxfModel = new DxfModel(DxfVersion.Current); DwgWriter.Write(@"C:\Test\new.dwg", dxfModel); // Load a DWG created in AutoCad 2019 in the AC1032 format, and save it to a file. // This file will also trigger the student version message. var inputFile = @"C:\Test\test.dwg" sourceModel = DwgReader.Read(inputFile) var outputFile = @"C:\Test\outTest.dwg" DwgWriter.Write(outputFile, sourceModel);

BricsCad has apparently had this same problem but seem to have patched it since then. https://forums.autodesk.com/t5/autocad-forum/autocad-2019-showing-quot-student-version-plot-stamp-detected/td-p/7941399

Hi! I have the same issue with WW.Cad.NetStandard 1.0.0-rc61 (trial license) and AutoCAD 2021. For both files saved with "ac2018" file format and "ac2013". Is there a problem with NetStandard version of library? Reply

Hi, It's a limitation of the trial version. - Wout Reply
