I attached some beam systems to a work plane "x". I need to change them and have created a new work plane "y". When I click on my beam system, go to edit work plane, and try to specify new work plane - only ref planes "a", "b", "x" show up. I have about a dz. different ref planes in addition to "y". Can anyone tell me why they do not show up in the pull down menu and why I can't change my beam system from one ref plane to another?
I've tried "disassociate" and am not getting anywhere with that either.
I've already had to scrap and re-draw this all once. I thought there was a way to change this without having to start over every time a slope changes.
Fyi - all my planes are named and I've tried actually rotating the ref plane line more than once, it doesn't work.
