The ability to pick on one part of a network and right click and say draw part(s) in profile and have it draw ALL the parts of the network selected into the selected profile! BUG!
Now if you do this only the part selected gets drawn in the selected profile view. You must grip, right click choose draw in profile, then hit escape, and the a hard enter and now you can choose one part of the network and it will add all the parts into the selected profile view. Again more of a BUG but its been around for so long I think it now as designed!

You can run the command from the ribbon without clicking on a part first.
Personally, I made a keyboard shortcut for the command ADDNETWORKPARTSTOPROF.
