While in Surfer's 3D View, you can use the mouse wheel to increase/decrease the height above the surface. You can also hold the mouse wheel or center button down and drag the mouse forward/backwards to move up or down.
If you want to enter the exact value of the height above the surface, follow the steps below:
- In the 3D View Contents window, click on Environment.
- In the Properties window, click the Camera tab.
- Expand the Position header, if necessary.
- Enter the elevation you want as the Z Position (in elevation units). For example, if you want to be 50 meters above the surface (assuming your Z units are meters), add 50 to the value displayed in the Z Position field.
