Add Flat Area

On the Mining | Pit Design (Dynamic) tab, in the Constraint group: Click New Flat Area | Add Flat Area to use a selected polygon to define the flat area.

In Shrinking mode (Pit/Down, Dump/Up), an External constraint will place the pit build area outside of any intersection between constraint polygon and pit string. In Expanding mode (Pit/Up, Dump/Down), constraints always expand the pit build area.

If not already selected, you will be prompted to select polygons to add as constraints.

Note: You can select multiple polygons using the CTRL + click shortcut.

Alternatively, you can Digitise the required object/s using the button in the Selection Assistant toolbar. The Selection Assistant will close, providing access to the tools used to create the object.

Select the polygon/s for the constraint. Click Accept Selection. The constraint will be added to the design with the selected polygons.
