mhh.. I do not think that it would work. scince the relative movement command "move -os x y z" (not move -r x y z ) uses another coordinate-system, other axes. Ahh.. Perhaps there's the problem. You're right, the relative movement command is "move -r x y z" and is the same as that what you've written...
But what I want to do is to use the Local axes of the object to move it.... That is the command "move -os x y z" In my Picture you'll see what I mean. I want to move, or be able to move the activators of the chevrons a bit (r in the picture) to the center. Therefor I need to move them a bit along the x and a bit along the y axes (y = cos(40)*r; x=sin(40)*r) with the relative movement (move -r x y z)
With the command I meant, the command which uses other local axes you just need to move them along ONE single axes...

How can I use this command in an expression?
