To add it to PartDesign Part feature you would i guess simply drag and drop it in it (tree view). After you can move the result (Part feature) around freely. If you would like to create PartDesign Body feature out of it. I guess you can't do that ATM. What you can do instead is install PoM and use its Module feature:kcleung wrote:Also, suppose if I make a CSG solid under the Part workbench, then how can I make a part out of it?
Currently I can't find anyway to do it under the Part or PartDesign workbench.

You can add CSG solid in a PoM Module feature. To get functionality like the Tip. And after you can add the Module to PartDesign Part feature (drag and drop in tree view) if you want that.
