Thanks. That was working well for me in plan view. Still a bit stuck (but not quite as stuck as earlier). Here's a different view on what I'm trying to do:
Three layers. Lights, truss, and venue.
Everything was drawn with a z coord. of 0. I want to move the lights and truss to a trim (z coord) of 30'.
Using plan view, i select specific lights, and the truss they are hanging on. How do I then specify the trim and have them move there together?
Once they are at trim, how do i use isometric views to check on their placement. It seems like i have to have one design layer selected, rotate the view, and then use "align layer views". Is there a way to spin around the rig with all layers moving in tandem? I've found that this can be done in a viewport, but then i can't directly edit without going back to plan view.
Can i have a second viewport window open on a different monitor while working with the plan view in another window?
I really appreciate any help. I feel like i'm pretty savvy with this kind of stuff, and i'm feeling bewildered by the power (and difficulty) of VW.
Thanks!
