Hello,
I am considering upgrading my software to .NET, but a big factor of whether I upgrade or not is the graphics speed of CadImportVCL in .NET. Do you have any side by side comparison of drawing speeds? From my testing with the demo versions, the .NET seems slower...Please advise.

Thanks,
TS

Hello,

Thank you for the queston.
We made some tests and result is:
Loading:
DWG 16.5 Mb - <b>CADImportVCL</b> vs <b>CADImport.NET</b> - 15 sec : 43 sec
DWG 4.01Mb - <b>CADImportVCL</b> vs <b>CADImport.NET</b> - 3 sec : 9 sec

Drawing:
DWG 16.5 Mb - <b>CADImportVCL</b> vs <b>CADImport.NET</b> - 3 sec : 39 sec
DWG 4.01Mb - <b>CADImportVCL</b> vs <b>CADImport.NET</b> - 1 sec : 11 sec

CAD Import VCL uses Win32 API. CAD Import .NET uses .NET Framework. Loading binary formats and paint operations in Win32 work much faster than under .NET. CAD Import VCL and CAD Import .NET have got similar code. We work constantly on improving VCL and .NET speed but .NET will be always slower.

Sergey.
