Before we start to setup our mesh, we need to know what height to set it out to. Have a look at your Surveyors information and find the lowest height supplied. In my example below the lowest height contour is 50.5m
As a rule of thumb, I always round down to the nearest whole number. In this case I will use 50.0m
Now I go to my zero story and open up the Mesh settings. Under Geometry and Positioning, the top value I leave at 1000mm. This is the sectional depth of the Mesh I am about to create. Underneath that I enter in the value of 50000mm. This will position my 1m thick Mesh 50m above sea level.
