Regions in T3CD
Create workable regions
Press Regions to divide a field into multiple workable areas. Regions are not available in drain-related functions. Each region can use different design options, such as different primary and secondary slopes or different levee designs.
NOTE: Different regions can use different design types: for example, a best-fit plane in one region and a multi-fit surface in another.
Split regions
- Position the splitting line across two edges of an existing region, or across the whole field if no regions exist. Move Point A and Point B directly with the touchscreen or mouse.
- The split line is straight. To create a multi-segment split, tap and drag the white nodes.
- You can split multiple times, then merge regions to build complex region shapes.
In the Circle Guide and Levee design tools, region splits use circles/levees instead of a line. These allow custom splits for pivot irrigation fields and rounded corners.
Merge, hide and restore regions
You can merge regions that are far apart. If one region contains two separate areas, position the split line between the two parts and press Split to separate them.
Apply a design
When you have finished adding regions, press Design.
In multi-fit, best-fit, smoothing and levees, use the drop-down menu to select a region. Design changes then apply only to the selected region.
Choose whether to apply your design to the original elevation surface or to the design surface.
