Hi, the DWG-file attached can't be read by CadLib for unknown reason. DwgReader.Read return "Cannot resolve handle. " exception. The dwg file was created with CadLib. I'm using CadLib 4.0.38.123 Best regards, Bogdan

Hi, Please download the latest CadLib version from your resources in your profile. There were some broken object references in the file. I see that you created the DWG file with CadLib 4.0.38.123, do you have the original input file that was used to create this? I suspect there's a problem with writing the DWG file that caused this. Thanks, - Wout

thanks, I uploaded both files try { string dwgPath = @"C:\VSSources\BadDWg\InitialDwg.dwg"; string outDwg = @"C:\VSSources\BadDWg\Exported.dwg"; DxfModel model = DwgReader.Read(dwgPath); DwgWriter.Write(outDwg, model); model.Dispose(); model = DwgReader.Read(outDwg); } catch (Exception ex) { }

Hi, Do you have any news on this? This is time sensitive for us.... Thanks, Bogdan

I already wrote above there's a new CadLib version. - Wout

Hi, I downloaded the latest version 4.0.38.136,again, and the issue is still there. I will reattach those 2 dwgs. Thanks,

It was fixed in 4.0.38.137, released on 1/18/2019, it should be in your resources. Version 4.0.38.136 is from 1/15/2019 is from before your report, so it can't have the fix obviously. - Wout
