Cut/Fill Mapping

Introduction

Cut/fill mapping

Cut/fill mapping enables you to:

• Display the cut/fill differences between the recorded elevation data and the guidance surface.

• Display an initial map generated from the cut/fill differences between a pre-mapped surface transferred onto the machine, called a ground surface, and the design surface. This initial map is then updated as the machine works and records elevation data.

  For example, the ground surface is produced in the office from a survey of the original site and transferred onto the machine. The initial cut/fill map enables you to plan your work around the site more efficiently because the high and low areas are easily identified in the work screen.

  The ability to select a ground surface is a licensed feature. Contact your dealer for more information.

The Cut/Fill Mapping shortcut key

You can also touch and hold the shortcut key to open the Cut/Fill Mapping screen.

Cut/fill mapping rules

The data is displayed in the following way:

Color	Meaning
Shades of red (cut)	The shaded area is above the current design surface (including any Elevation Offsets).
Shades of green (on-grade)	The shaded area is within the on-grade tolerance of the current design surface (including any Elevation Offsets).
Shades of blue (fill)	The shaded area is below the current design surface (including any Elevation Offsets).
Gray	Cut/fill values are being calculated and loaded.

Starting cut/fill mapping with an empty map

To start mapping with an empty map:

1. Optionally, toggle Display Mapping Data on or off.
2. If available, from the Ground Surface drop down, select None.
3. Tap Apply.

Starting cut/fill mapping with a pre-mapped surface

The ability to select a ground surface is a licensed feature. Contact your dealer for more information.

To start mapping with a pre-mapped surface:

1. Transfer a ground surface .ttm file onto the machine. Either sync with Connected Community or import the ground surface file from a USB flash drive.

   NOTE – If a Connected Community sync adds a new ground surface .ttm file to the current project, then a notification is displayed.

   NOTE – To import a ground surface .ttm file from a USB flash drive, the ground surface file must be in the ProjectLibrary \ Projects \ [project name] \ OfficeData folder on your USB flash drive.

2. Optionally, toggle Display Mapping Data on or off.
3. From the Ground Surface drop down, select the ground surface file to load.

4. Tap Apply. If Display Mapping Data is on, a cut/fill map is generated showing the difference between:

   • The guidance surface of the currently loaded design; and
   • The ground surface

As you work, the pre-mapped ground surface elevations are overwritten by the measured elevations.

If you select a different design within the same project, the cut/fill map regenerates using the new design.

Downloading ground surface data from an online source

If your technician has enabled access, you can request the system to download the latest ground surface data in a .ttm file from an online source. This includes data from other machines on the site.

This option downloads data once when requested.

1. On the Mapping screen, set the Ground Surface field to WorksOS download.
2. Tap Apply.

Downloading information for a large area can take a while.

This feature requires an Advanced Mapping license. A machine can only download ground surface data for a compatible design.

Resetting cut/fill map data

To reset any existing cut/fill mapping data stored on the machine:

1. From the Work Settings menu open the Mapping screen, or touch and hold in the shortcut bar.
2. Tap Reset Map.

If a pre-mapped surface was initially loaded and Display Mapping Data is on, then the cut/fill map of the differences between the design surface and the pre-mapped surface is reset to its original state.

You cannot delete compaction mapping data.

Inspecting a map

To view details of the mapping data on a plan view, touch-and-hold on an onscreen location where mapping data is recorded. Select Inspect Map from the context menu.

When a design surface is loaded that contains different slopes and gradients, mapping colors may appear to vary slightly across the changes in grade. This is expected as the display applies different surface shading to the different slopes to make it clear that there are changes in slopes and gradients. Using map inspection, you can confirm the actual value of the mapped data in specific areas if you are unsure from the colors alone.
