The Windchill REST API can be used to retrieve all drawings of a particular part.
What is the other way around?
Which API request(s) must be used if you know a CAD document and want to receive all the parts associated with the drawing?

Thanks for the hint. This might be the solution. ".../CADDocumentMgmt/CADDocuments" is supported since REST API 1.4. We're using 1.3, so I'll check this after updating to the latest version.
