My cut/fill map is totally a single color representing no cut and no fill.

Symptoms:

In the implementation or design phase of T3RRA software, you view a cut/fill map and it is a uniform green or gray color representing no cut and no fill (depending on your cut/fill color schematic selected in Settings). When you touch part of the map it shows the Cut/Fill value as being 0.

Cause:

1. Your original surface and your design surface are exactly the same. This happens if no design has been created. When surfacing first completes a “blank” design is created that matches the original surface exactly. As a cut/fill map is the difference between the original surface and the design surface it will necessarily be a map of zero values.
2. Your ‘Zero Cut/Fill Range’ is too large.

Solution:

1.  Go to the design step of the wizard and create a new design. 
2. Open Settings > Application and lower your ‘Zero Cut/Fill Range’
