I know I have done this in assemblies but cannot for the life of me remember how.  I have been working on a project in ProE for the last few weeks and I am readjusting to SW.  How do you this and can you do it in a part?  I know how to add it to the list with the new name but how to pick two surfaces for orientation.  Handy when you don't have a plane for everything.  Someone jog this altered memory!

thanks

Bonnie

edit: using 2011 PS2.  I know I did this in 2010 but cannot imagine it was removed.
