Hi all, I am in training for vectorworks and I am trying to recreate an example sheet as an exercise. I'm having an issue with recreating a perspective viewport, I'm trying to get the delta x, delta y, x, y, scale, etc from the object info palete all identical to the example sheet. The problem is, when I edit one, then one or more of the others change, and I can't seem to get them all to what they need to be. I can't seem to locate the problem, any ideas?
