Overview   T3RRA Cutta Desktop offers several tools for analysis beyond what is included in our In-cab packages. These tools allow the user to further analyze and understand how their design will perform once implementation has been completed. Circle Guide - Creates a circle for reference on the surface. Elevation Grid - Overlays a grid with elevation values at each junction. Flow Paths - Overlays arrows in a grid pattern that show the estimated direction of flow at                       each junction. Watershed - Identifies the areas of the surface that will flow together to the same exit point                     on the field. Edit Markers -  allows you to view, edit, and create markers on the elevation surface.
