6.3 | Blade Control Modes

AllowsBlade youControl toModes specifydetermine how Level COMMAND interprets the design surface beneath the blade when calculating the required target position.

Different grading situations benefit from different control strategies. Some modes prioritise accurately following the design, while others minimise overcutting or improve performance around sudden changes in terrain.

Selecting the appropriate Blade Control Mode can improve grading efficiency, reduce rework and produce a more consistent finished surface.

The available Blade Control Modes are described below.

Typical applications include:

This produces smooth grading performance across broad, continuous surfaces and reduces sensitivity to small variations in the design.

Typical applications include:

This mode is particularly useful for constructing features where one point of the blade must accurately follow the design.

 

Typical applications include:

When Single Point is active, the Swap Ctrl button is displayed in the Back View. This methodallows the active control point to be quickly swapped between the left and right sides of the blade when changing travel direction.
