DWG to PDF conversion, layer color is not preserved


I saved a DWG file as a PDF file, the layers are recovered but they are in black and white, can you tell me how to recover the color of the original file?

In addition, the convention is very slow, is it possible to speed it up?

I have attached the source code and files

Thank you Best regards

Please apply this option to get color result:

rasterizationOptions.DrawType = CadDrawTypeMode.UseObjectColor;

As for the performance we will look at this problem in more details in the scope of the issue mentioned below, but I’m not sure we can improve this a lot as there are 48K of entities (including 1K blocks) which require some time to process.

Thanks with this option I recover the color.

Indeed the file is large, I am waiting for your feedback to know how to implement the functionality in our software.
