Make 3D Regions

To access this screen:

Optimization control bar >> Ultimate Pit >> Define Slope Regions.

You can make 3D Slope Regions used by pit optimization and pushback generation from 2D Slope Regions and/or separating surfaces. Note that 3D Slope Regions can be made exclusively from 2D Slope Regions, exclusively from separating surfaces, or from a combination of both.

Once generated, a 3D region file becomes available for selection in the Pit Optimization Settings screen (Slopes tab).

Note: For large models and numerous 2D regions, it can take a while to create 3D regions

To define slope regions for pit optimization and pushback generation:

Display the Make 3D Regions screen.
Expand Choose 2D Slope Region definition to select 2D Slope Regions.

Note: You must have digitized or imported 2D Slope Regions beforehand, or the only option available is No 2D regions.
Under Choose 3D Separating Surfaces, select an indicator file from the list of available definitions.
Select the First surface code. This is the first separating surface you wish to use; the default selection is the first surface in the file.
Select the Last surface code. This is the code of the last separating surface you wish to use; the default is the last surface in the file.
