Super useful feature!
When applying a vertical curve to a linestring, you can enter based on you PVI but really I want to enter based on the elevation of the actually curve at this point because everything is going to be controlled from this, especially when using the vertical design tool.
Or at least calculate the perpendicular vertical elevation to the PVI so the user can adjust this.
I could create an excel calculator for this but that would require a lot of extra steps for input especially where all of the necessary parameters are already built into TBC, and TBC is doing the math anyway. Maybe have this show below with the incoming slope/outgoing slope results.
