Hi
I needed to have a drawing and partlist of all ipart-members once. I generated all the files of the ipart and copied them all into a new assembly. This way the partlist included all members. I didn't need to show the actual assembly on the drawing so I placed it outside the frame of the drawing. You can also place a partlist on a drawing by selecting the source-file from the browser, so you don't have to have a view of the actual assy for the partlist.
One other possibility is to create a simple iassembly with the ipart. Then you also will have a partlist with all members. But all members (but one) has qty=zero. Just make sure the choice "hide all members with zero qty" is not chosen for the partlist.
Hope this can help
Best regards
