Starting Implementation
T3RRA Software implementation startup instructions for UCC1 1. Drive to a zero cut/fill area and place the scraper cutting edge on the ground. Drop a marker for future reference. (when zeroing on drains ensure that the position indicator is on the drain surfac...
Understanding how "Pass Count" works
The ‘Pass Count’ map is a representation of where activity has occurred in the field. It is similar to a normal coverage map seen in agricultural applications such as spraying. In a regular coverage map the tractor and implement normally only pass over a locat...
Understanding how "As-applied" works
When moving earth there are three states:What you started with.What you intended to do.What you actually did.You start with the original field surface. You intend to end up with the field surface matching your design. An “As-applied” (or “As-built”) map is a r...
Understanding the relationship between the "As-applied" surface and the Dynamic Blade Limit.
The Dynamic Blade Limit (See the section of “Static Blade Limit” in the Limits Tab for disambiguation) relies totally on “As-applied” functionality to work properly. If this is not activated, or is not working properly, the blade limit will not work.T3RRA soft...
The Implementation Screen
When you begin implementation of your design, the display will show a cut/fill map as well as tools to assist in the implementation of the design. Screen features of interest include include: Setting Zero button. Cross-slope nudge control buttons....
1. Setting Zero
Important: Before work can begin, the system must be “zeroed”. Both the T3RRA software and iGrade™ must be zeroed. Important concepts: Benchmarks. Benchmarks are “control points”. These are known locations in or out of the field that can be ret...
2. Cross-slope Adjustment
T3RRA software is capable of sending cross slope commands to iGrade™. It can operate automatically based on the cross slope observed on the map at the current location. It can also be switched to manual and a cross slope value entered. To enable control (m...
3. Vertical blade shift
The blade shift buttons in T3RRA Cutta and T3RRA Ditch serve to manually shift the height of the blade, either up or down. The distance a single press will shift the blade vertically (called the ‘Blade shift increment’) is set in the 'Settings' window. As the ...
4. Cut/Fill information display
In the upper left corner of the screen more information is shown about current ground height, design ground height and the amount needing to be added/removed. The Horizontal color bar will display a color graded scale of cut and fill amounts and the white mar...
5. Progress bars
In the upper right of the screen are 2 percentage counters that show the amount completed. These are only shown when 'Enable as-applied calculations' is turned on. NOTE: the percentages count up what has been implemented so far, not what is left to do...
6. On-grade indicator
At the left side of the map screen there is a grouping of up/down chevrons that show the current blade height relative to the target design height. They show how far the blade needs to move, and in what direction, in order to be “on grade”. If two GPS units a...
7. Blade and Tractor Indicators
When you are implementing a design, each implement will appear as a triangle pointing towards your current heading much like it did in surveying. The tractor is not displayed. The triangle indicators display GPS statuses with color changes. The inner triangle ...
8. Map Display
When implementing the display will show a cut/fill map by default. The Cut/fill map will be displayed using the color settings you have set in the 'Settings > Application' window.Red/Green/Blue Magenta/Green (default color setting)The Magenta/Green color schem...
9. Drain Profile
When implementing a drain you are able to bring up a display on the screen that shows the profile and cross section of the drain. A small circular drag handle can be found at the bottom of the screen. Double tapping, or dragging this handle will display this s...
Surfacing
"Surfacing" is a term used to describe the process of creating a continuous map (i.e., a “surface”) from all the discrete elevation data points collected in the 'Collect' wizard step. This is done so that every location in the field (or work area) has an...
Setting the Search Radius Manually
If the automatically generated search radius does not achieve what you expect it is possible to manually adjust the search radius in the bottom left corner of the surfacing page. There are a few things to take into account when manually adjusting the search ra...
Inline Offset
'Inline Offset', also known as 'Fix Lag', is a surfacing tool that assists in making corrections to elevation data that is imported from other sources. To access this tool press the ‘Fix Lag’ button located at the left end of the tools at the bottom of the sc...
Surfacing a Survey also creates a design
This is a concept that can be confusing at first. When you surface a set of collected survey points you create a terrain model of the original elevation in the field. This is expected. But T3RRA software also automatically creates a design surface for you as w...
Survey point edit controls
During surveying and surfacing, there are various different ways to edit/remove drain and survey points. Field survey points are small circles, and drain survey points are small squares. The available tools include selecting by Z (indicated with a histogram), ...
Survey Point edit controls
During surveying and surfacing, there are various different ways to edit/remove drain and survey points. 'Select by Z’ allows you select elevation points by their height. After you click on it, you’ll see a graph of all your elevation data. Choose the data ...
