Sorry for the silly question but I'm stuck. It's hard to describe what I want to do with words so I'm attaching an annotated screenshot.
Basically, I need to translate procedurally the wire in the picture so that the top point (A) is always at 0,0. The closest I could get is using the expressions you can also see in the picture. Y alignment works but X alignment is offset because if use bbox D_XMIN the “left-most” point (B) is not on top but around the middle of the wire. Hope this makes sense. Thanks!
