Something I find interesting @vince is that the “Perimeter” tool doesn’t show in my left toolbar. This may just be a setting, but it makes me think that “Polyline” is the preferred tool.

Using a separate column for rise/drop is an interesting idea. I’m considering a major custom column overhaul of my markup tools before too long. I’ll have to add that to my potential list of upgrades…
