I know edrawings can be used as a markup tool for SW files,but what is the typical way to use this as it related to PDMWorks?

If a user simply right clicks on a SW file and selects View/Markup,edrawings opens the file read-only. If a user marks up the file andwants to save it, the file can be saved and checked into the vaultas an edrawing file, but I don't see any kind of automaticreference back to the SW file it was created from. If the user haswrite access to the SW file, it looks like the markup info is savedwithin the SW file and no edrawings file is created.SolidworksEdrawings
