The Vertical exaggeration option sets the scale for the Z direction for the entire project, where it’s the ratio of the X and Y scale over the Z scale. For the Vertical exaggeration to be calculated and reported correctly, the X, Y, and Z units should all be the same units. For instance, all of the values should be in feet or all of the values should be in meters.
The Vertical exaggeration can range between 0.00001 and 100000. A Vertical exaggeration of 1 is considered no Vertical exaggeration. This means that the distance covered by one page unit vertically is the same as the distance covered by the same page unit horizontally. When set to 10, the distance covered by one page unit vertically is ten times as large as the distance covered by the same page unit horizontally.
