Adjust the vertical exaggeration of your model in Surfer

By default, Surfer creates 3D surface maps with a 1.5 inch Z axis, regardless of the scale.  Any vertical exaggeration in the Z direction is due to this fixed default.  To adjust the Z scale (vertical exaggeration), follow the steps below.

  1. Select the Map in the Contents window.
  2. Click the Scale tab in the Properties window.
  3. In the Z Scale section, adjust the Length (page units) or Map units per inch to the desired value. Setting the Map units per inch for the Z Scale to match that of the X Scale and Y Scale will result in a vertical exaggeration of 0.
