we’re currently testing the Aspose.CAD API. It works fine for DWG files, but we have Problems converting newer HPGL / 2 files. Are there any known limitations with that format?
I have observed your requirements and like to share that the API does support PLT (HPGL) format. However, support for HPGL/2 is unavailable in API. Can you please share the source file along with used sample code and issue details so that I may log issue as feature request.
