How to use the Rosette function on the Dynamic Pit Design

When designing a Pit using the Dynamic Pit Design tool, it is possible to add some variables constraints by using a Block Model, Wireframes, Polygons and/or Polylines.

Within those constraints, there is an option to use the ROSETTE function when creating an expression to define a Slope angle and/or Berm width. In this article you will learn how to write use this function.

In this example, the Polygon Zone is being used as a constraint. To edit an expression, just press the function button on the right to open the Expression Editor dialog:

On the Functions, Operators and Conditionals open the Maths drop-down menu and choose ROSETTE (double-click to select it.

In this function you will need to define the azimuth, the specified parameter and if you want the software to interpolate the values or not.

In this example, the slope angle is being defined. 

The expression used is ROSETTE("-90,90; 90,45", [Projection:Azimuth], {TRUE})

Between ".." it has to be written first the azimuth then the slope angle. Azimuth -90, slope angle 90 degrees; Azimuth 90, slope angle 45 degrees.

In the end of the expression, you can specify if you want to interpolate those values. By writing {TRUE}, there will be NO interpolation:   

If the {TRUE} is removed, there will be interpolation:

With that, you can define different slope angles/ berm widths for different azimuths by using different variables constraints.
