Autocad Civil 3D: Increase of surface elevations by n times

It is possible to increase/decrease each surface mark by N-times. It is convenient for checking for errors on an extended surface whose height differences are relatively small. The Scale Factor of 10 allows calm terrain to transform hilly terrain.
To do this, go to the "Triangle Display mode" tab - "Exaggerate Elevation" and set your own triangle scaling factor. Next, we extract 3D-Faces from the Surface and build a new surface using them with an enlarged elevation set according to the scaling factor
Exaggerate Elevation: Scales the triangles by the factor specified in the Exaggerate Triangles By Scale Factor property
