Convert DWG to PDF using CTB

Hi, I’m using the evaluation version of Aspose.CAD for .NET (v and I’m facing a problem.
I want to convert some DWG files into PDF using a CTB file to inherit the line weight but i can’t find anything in the guides.
Is there any kind of class that can do the job that I need?

In the attachments you can find an input example, the ctb file, my output and the desired output (obtained using AutoCad).

Thank you in advance. (3.6 MB)
