3. Settings Application Tab Units: ‘ Language ’ -  Changes the language ‘ Length ’  - Changes unit of distance measurement. ‘ Area ’  - Changes unit of area measurement. ‘ Volume ’  - Changes unit of volume measurement. ‘ Estimated Cost ’  - Set an estimated cost per volume of dirt moved. To customize the currency format, click the button to the right. You can enter custom text before and after the amount. An example is shown on the right. This allows you to put your currency code and other information before and/or after the value. Cost per cubic meter, or cubic yard (this is calculated for cuts only).   ‘ Surface Grid ’  - Determines whether or not to show the grid lines on the map. By default the grid changes size to best fit the size of the field. Dimensions for the grid size are displayed in the lower right corner of the scanned area.  ‘ Lock grid size to: ’ -  Users can adjust grid size manually. set to 0 for auto-size. ‘ Cut/Fill Color Style ’ -  Set colors used for Cut/Fill to Magenta/Green or Red/Green/Blue. (Magenta as cuts/Green as fills, or Red as cuts/Green as neutral/Blue as fills) ‘ Surface Color Style (Low,High) ’ -  The surface color style allows you to change which colors represent your highs and lows. (this is limited to selecting from a drop down menu) ‘ Zero Cut/Fill Range ’ -  Adjusting this number allows you to set a vertical range that will be considered as “on-grade”. This is a great tool for quickly identifying parts of a field with heavy earth moving. This option will not change the design height or the height of the scraper blade.  ‘ Slope Display ’  - Show slope as a Percentage  or as a Ratio .

Click the green [Accept] button to accept their help. Close  - Choose to save settings and exit this settings dialog. Machine Tab Look ahead delay time  - In order to control blade height the software must receive an elevation from iGrade™, process that elevation, and then return a control signal to iGrade™. This control loop is quick but the time delay can cause inaccurate implementation in certain situations. A normal “Look ahead” time is 0.3 to 0.5 seconds.  The exact time is machine specific and can be determined through experimentation (see  Bi-Directional error in T3RRA in the troubleshooting section) . The look ahead time helps to account for the delay in the control loop. If the look ahead time is not set the delay can cause a “bi-directional error”. This is where the blade offsets incorrectly, moving up when going down a slope and down when going up a slope. This error occurs consistently. If the look ahead time is set too LOW the implement will always grade high when going down-slope and low when going up-slope, the opposite effect will occur if the look ahead time is set too HIGH. Bi-directional error is most noticeable when working steep slopes at higher speeds. Receiver setup  - The 2 drop down menus set which sort of receiver connection is being used(left) and the number of receivers that are connected (right).  The receiver connection type in the left drop down menu has 4 options: Auto-detect (default) Non-IGrade IGrade 1 IGrade 2 The number of receivers (Implements) can be adjusted using the right drop down menu: Single Dual implements Two receivers on one implement Triple implements.  T3RRA will use the front GPS receiver for any multi-bucket configuration, and both GPS receivers when set to "two receivers on the one implement". When using multiple receivers, iGrade™ has the ability to control SCV1 and  SCV3. Ensure SCV1 and SCV3 are configured correctly for remote control commands by placing them in detent, for information on how to do this refer to “ How we work with iGrade™ ”. When utilising dual or triple scrapers on UCC2 you may need to adjust the receiver height settings in the receiver settings in the individual receiver menu in ISO Page. Refer to your iGrade Manual for instructions on adjusting individual receiver height offsets. When using multiple scrapers with UCC1, the receivers must be mounted at the same height above the blade. Also with UCC1, implement offsets cannot be entered in the display to account for mounting error. NOTE: To lower the blade enter a higher receiver height. To raise the blade position lower the height set in the receiver setup. 'Use Tractor GPS for surveys'  - Only available with iGrade UCC2. When selected, the Tractor GPS will be used for surveying when it has RTK. Otherwise, it will fall back to standard operation. Implement width  - This value reflects how wide the implement in use is and needs to be entered manually. This value is needed for ‘Cross slope’, ‘As applied’ and ‘Pass count’. Implement settings: Output cross slope commands  - The amount each tap of the manual left/right cross slope adjustment buttons causes the cross slope to change by during implementation. Uses percentages (not degrees). Cross slope nudge increment  - This specifies the incremental amount each press of the left and right tilt buttons will add to the cross slope. Blade positioning  - Allows the operator to specify which part of the soil profile under the blade has priority in determining blade position. This option is only available when you have entered an ‘Implement width’ and enabled to ‘Output cross slope commands’. Classic   - This position uses the design elevation as the target elevation under the center of the blade, and the cross-slope is determined by the design elevations under the left and right points of the blade. With Classic, it is easy to over-dig when driving down the midline of ditches, or to clip the top off a bank when straddling the ridge. Average   - This position looks at the design surface under the blade and goes for the overall trend. This is great for taking any full-field design and giving you basically that. It’s not so good for abruptly changing slopes, however. Average, on top  - This position is one step up from the trend method, literally. It determines the slope in the same way as the ‘Average’ method, but it always avoids overcutting. Snap fit  - This position attempts to find the best blade position, without overcutting. If you are going over a break line, you will see the blade snap from one position to the other as you traverse the break line. What it means, though, is that you will be cutting and filling most efficiently, minimising the number of passes and risk of rework. This option has been tailored for abruptly changing slopes. Single point  - This position is what everyone seems to want − Control-by-point. In this configuration, you pick a position on the blade represented by the red arrow. That point on the blade will be at the design elevation and cross slope even if it cuts below the design elsewhere. This is envisioned to be great for digging features like V-ditches. Enable As-applied calculations  - As-applied calculations show a graphic representation of the surface's current state as work progresses. For more see  Understanding how “As-applied” works NOTE: ‘Implement width’ is required to enable the As-applied feature. Enable Pass Count Tracking   - Pass count tracking shows how many times you have gone over a particular spot, an indication of the amount of work that has been done in an area. For more see  Understanding how “Pass Count” works NOTE: ‘Implement width’ is required to enable the Pass Count Tracking feature. Note : ‘Enable As-applied calculations’ and ‘Enable Pass Count Tracking’ are set to for each system, if a different Cutta system is used your setting won’t be remembered. Find below answer to some frequently asked questions regarding implement profiles: Q :  Is it a requirement for everyday implementation to fill in  Maximum blade clearance  even if you are NOT choosing/entering an Implement Profile? A :   It is not required. It is an organizational tool to create efficiency in workflow. Q :  Does the Implement profile named "Project profile" reflect the Maximum blade clearance entered? A :   The Implement profile saved will reflect all parameters entered for that profile. Q :  Am I required to use the same RTK base station for surveying and implementing (I  will  be using the same implement)?  A:   To benefit from the Implement profile Maximum blade clearance tool, it makes most sense to be using the same tractor, implement, and GPS base. Q :  Can I use this with drains created in Auto Drains? Pattern Drains?  A :   Yes, if you surveyed with the same equipment you are implementing with. Q :  How do I disable this setting?   A :   Selecting a saved profile is the best way of knowing you are utilizing the Implement Profile settings for that equipment. It does not make sense to ‘disable’ an implement profile as the settings that make up an implement profile are always going to be required. Q :  When pulling multiples, does this apply to  only  the implement using SCV 1? 2? 3?  A :   Maximum blade clearance refers to implement utilizing SCV 1. Q :  Do I need to set zero at the first drain and then I will not need to set zero again when digging the other drains?  A :   Not if you have selected a saved profile and both surveyed and implemented with the same equipment. You will need to have entered or calculated the proper blade clearance. Q :  If I swap out tractors but still use the same implement, do I need to reconfigure the blade clearance distance?  A :   You will need to create a new Implement Profile and name it something that describes the equipment associated with the profile. Project Tab Settings made in the project tab will not be represented in a project that is open when the settings are changed. Surface Pixel Size  - The default pixel size of 2 meters (~6 feet) should be adequate for most purposes. In some situations, it may make sense to decrease pixel size to 1 meter or even 0.5 meters (primarily to facilitate small interval contour creation, or to get good definition on drain batters/backslopes).   A field surface is represented using a “raster”. This is a grid of elevation heights. The individual cells in this grid are referred to as “pixels” and have a uniform edge size. The smaller the pixel size, the more pixels needed to cover a given area, and the more precise the elevation surface is. Points of interest If pixel size is too large then the field surface will not appear smooth, and short range changes in elevation may not be adequately represented. If the pixel size is too small, then the computer will have to work harder to process the data.  Dividing the pixel size by two increases the amount of pixels by four. New Project Defaults will populate for brand new projects. Users can then choose to alter or apply them: Project offsets These settings allow for any GPS discrepancies to be accounted for during implementation.  The ‘North/South’ and ‘West/East’ directions to move the map (+ is North, - is South) (+ is West, - is East).   ‘Implementation’ is a vertical offset used during implementation only.  Limits Tab Blade Shift Increment   -Used to set the height adjustment value of the up/down elevation adjustments buttons in the implementation wizard step.  NOTE  - recommended distance for the blade shift increment would be 0.03 - 0.06 feet (0.4 - 0.8 inches, or 0.01m - 0.02m). Static Blade Limit   - This feature allows you to temporarily alter your target design heights by a certain amount. For instance, by setting the Static Blade Limit to 50% you will effectively be setting your target cut and fill heights to be 50% of what the actual design calls for. This setting can also be used to overfill a design by a percentage to allow for soil to “sink “ by a percentage over time. Having a setting of 110% will fill a 100mm fill to 110mm to allow for future compaction.  This is useful for building up banks, roads, or mounds in gradual steps and allows for even compaction of dirt. The checkbox ' Ignore cuts ' is useful if you want to gradually build up a mound of dirt by using the vertical nudge to lower a design surface below the current surface and then slowly nudge it upwards so that the fill pattern starts with the apex of the mound and proceeds outwards. In this case you do not want to cut in the regions where the mound design surface is currently nudged below the original surface.  NOTE : 'Ignore cuts' can be activated even if the Static Blade Limit is set to “None”. The static blade limit amount is set on the implementation screen.  Methods to progressively add layers of dirt to a fill area. Static Blade Limit by Percent Static Blade Limit By Absolute Value Combination of vertical blade offset  + Ignore cuts    Dynamic Blade Limit  - The increment which the blade will move per pass of cut or fill. It allows progressively cutting to a total depth without over cutting on an individual pass. This feature is designed to allow cuts to be taken in “bite size“ chunks without causing the machine to be overloaded. It can optionally be applied only to cuts, only to fills, or both. It uses the as-applied functionality to track blade heights on previous passes in order to set the current blade height. Dynamic Blade Limit does not operate unless as-applied functionality is activated. For more see  Understanding the relationship between the “As-applied” surface and the Dynamic Blade Limit.   GPS Port Settings Tab GPS  - Displays the COM port that is used to communicate with the GPS.  Ensure you have selected the correct port with  the drop down menu. Baud (Rate)  - The communication speed between the software and GPS (it should match the baud rate of the GPS). Scan for GPS - Checks the available COM ports and usual baud rates for valid GPS data.
