P1.DistanceToSurface(SurfaceTarget) - Vertical Distance from point P1 to SurfaceTarget (Point above = positive, point below = negative). The above is the reference that I'm using... So in the Condtion value I've entered the following expression, am I getting this right or NO?
False = Cut (below TargetSurface)
True = Fill (above TargetSurface)
Looking for some confirmation on if this is the right method to the madness? Thanks in advance.
That looks correct. What I do would do if I wasn't sure would be to add a point to the true side and then move the target surface inside of SAC up and do and make sure that it appears/disappears the way I expected.
