We did something like this.
We publish our drawings to PDF using OOTB CAD Worker functionality.
We use the Export functionality of the WTPart, which will create a jar or zip file. From there you can get the PDFs, unfortunately, they are in their own jar files and you need to extract them.
From what I've seen of 10, there is no functionality to easily expose the visualization files, but I haven't checked that much yet.
