In earlier projects, I found the Point Control by Elevation and Grade to be extremely useful when a tight radius causes overlaps out at one end of a template. With it, I can force all of the template points that come to the common point at the center of the tight radius curve to also come to a common elevation and I have 100% control of what that elevation is. And then, when transitioning away from the last point, I can also use it to return to slopes as defined in the template.
I do not see it in the any of the options nor any of the help documents? If it has been removed, how would an imported IRD file deal with this type of control?
