The vertical exaggeration shows you by how much the vertical scale has been distorted. Five times is a relatively good representation, however, an exaggeration bigger than five times become to distorted. The vertical scale chosen will therefore have a huge impact on the distortion of the cross section. Let's use a scale of 1cm represents 20m.
