Measure twice, cut once.  It’s an old maxim but a good one. You can do as many designs as you want in T3RRA software before you ever put your tractor into gear. Use our 3D visualization and rainfall simulation tools to carefully examine the effect of an...

One of the many unique features of the T3RRA product suite is our inclusion of a rainfall simulation tool. This allows a very visual and easily relatable analysis of how a field surface affects water runoff and ponding. It should first be used after a surve...

To create regions, press the ‘Regions’ button (regions are not available in drain related functions). The ‘Regions’ tool is used to split a field into multiple workable areas. Different design options can be applied to multiple different regions. For ...

Press the 'i' button to view earthwork details. Note: pressing within the ‘Info’ text box will expand the view to full screen. Each region will have its own set of  earthworks details and cut/fill summary. Press the 'Records' button (shown as ...

In some tools that require a value to be input a calculator will be available. The purpose of the calculator is to take some of the stress away from creating field and drain designs. In addition to being able to calculate, the calculator comes with a funct...

 Select the 'Best-fit' button to create a plane of best fit for a field. A Best-fit design provides a single plane that most accurately fits the existing topography. Using a Best-fit plane ensures that you move the least amount of dirt possibl...

'Multi-fit' creates an optimized non-linear surface with slopes between the entered minimum and maximum. Multi-fit balances the dirt down the field in the direction you specify. The balancing occurs within strips, and is great for working within rows and movin...

Select the 'Smooth' button to create a more regular surface with fewer and more gradual hummocks and dips. The smoothing strength can be adjusted to produce a stronger or lesser effect as needed. Regular Smoothing Regular smoothing applies an ...

 Select the 'Offset' button to raise or lower the surface height of a field or  region. This can help with: Importing and exporting dirt Addition or removal of topsoil Raising pads   You can either: Manually enter the desire...

When designing drains, there are several aspects that you will find that are across all the different Drain Design tools.  The most important feature of the drain design tools that you will find will be the cross section found at the bottom of the screen.  ...

You can use Auto-Drains to automatically generate drain paths for wet areas in your field. It will calculate optimal ditch lines to drain depressions. There are two tabs in Auto-Drains: ‘Create’ controls the parameters that must be met before drains are...

This design tool allows for simple design of many parallel drains at once.  The pattern drain window allows you to select specific drains to delete. The 'Delete' and 'Clear All' buttons allow you to either delete selected drains or all patt...

Drain paths can be created by: Surveying them in the 'Collection' wizard step Importing them Using the Auto drains tool Using thePattern drains tool Drain Design allows slope profile and cross section design choices before “burning” ...

'Levees' allows you to create repeating or singular levees at set elevations. Levees can be added at set intervals. Levees can be smoothed. Levees can be selectively deleted. Levees can be applied selectively to field regions. ...

Remember that guidance lines are only available for Drains and Levees. Should you wish to export guidance lines from T3RRA software for use with AutoTrac™ be sure to follow the following steps to be sure that the process is successful. Exporting begins by ...

Once satisfied with your design surface and/or drain.  1. Select the 'Return' button. (Top right corner)  2. Select 'Yes' to keep the design surface.  3. Select the 'Save proj.' button to save the T3RRA project. Once you have finish...

'Terraces' allows you to create Guidance curves to mark terraces for erosion control.When you first enter the terraces tool, a start line is displayed on the map. This is where your terraces will start from. There are a few parameters for terraces:‘Bank grade’...
