About Contact

Design like you mean it.

Professional desktop terrain design software built for professional farmers.

Feature Rich

T3RRA Design™ has more capabilities than any comparable software package on the market.


T3RRA Design™ isn't only for the big boys. T3RRA Cutta™ projects load directly at no cost. 3rd party data can be imported from many sources at reasonable, area-based rates.

Easy to use

Unlike the competition, T3RRA Design™ isn't a 'dumbed down' version of some civil engineering CAD package. T3RRA Design™ was built from the ground up for growers. You don't need an engineering degree to use it.
