Topographical points relative to existing geometry.

[MODENADarioMariuzzi]

Greetings,

It would be beneficial if you were able to place a topographical point relative to existing geometry e.g. 200mm below the top face of a sloped floor, similar to being able to place a point relative to the topo-surface itself

I will say "no to be relative to existing geometry" but that you could chance the Reference Level. Like when you are placing Elevation Tags.

And by default be referenced to the Survey Point elevation (not to the Project Base Point, with the posibility of change it if you want).
