Recently, I got some uni-classes which got uploaded through ProjectWise for my Project.
Question here is, How do I get those uni-class into local in case if I am working with the file locally (Check out/Through C drive)? Please advice. Thanks.
This depends on what the class is trying to accomplish. If they're just distributing files and you aren't expected to work with others via projectwise, or you just want a backup copy, then you're probably looking for the Export > Send To Folder option. That will dump out a copy of the files to a location you specify.
If you're expected to be working with others using projectwise then exporting data to work outside of projectwise is a bad idea. I explain further in another note here:
(ignore the inital part about powershell).
Note that when you check out a file to work on it, it is copied to your machine locally, just not in an easily discernible location. In a collaborative environment it's best to work with files via ProjectWise Explorer.
