Vertical distance between (angular) surface and XY plane (heat map)

Hi,

Following challenge;

There is a sloping surface.
I have made a projection on the XY plane.

Question;

  1. I would like to get the ‘vertical’ distance between the surface and the base plane XY, and plot it in something like a heat map. (colors represent the vertical distance).

  2. In the heat map there should be a difference in colour for the location where the vertical distance is

larger than > 2,0m (green)
less than < 2,0m (red)

Any suggestions?

Thanks :slight_smile:
