Civ3D11 - Displaying difference between two elevation surfaces

[Anonymous]

I've got two surfaces.  One surveyed/measured before some earthworks and one after. What I want to do is display over the entire area of the surfaces on a grid (2 or 4m)  the difference in elevation at each grid point..

Thanks, Dene

Assuming you have some C3D knowledge:

Create a TIN VOLUME surface with existing as base surface and proposed as comparison surface, then you can do fancy solid/transparent colours, coloured contours or spot levels over the surface.

As you askd for spot levels, you need to annotate the TIN VOLUME surface so, Annotate > Surface > Add Labels > Surface > Spot Levels on Grid. You choose grid spacing, rotation etc and it might take a few attempts to make it look like you want.
