I can't use 3d effectively for my job due to several limitations. However there's several situations where having a block to add would be useful but the views are at an angle and I'm not really allowed to use 3d shots. What I'd like is to have a vent with the manufacturers sizes, however I can update the block's viewing angle. So if I'm looking at a bellmouth vent from the top that's easy to create a block that updates. Not so easy to do a block looking from the top when the vent is at a 45 or 60 degree angle. My trouble is getting an input variable. I want to have a user input that changes the angle of attack but I'm not sure how to do that.
