Add Constraint (External)

On the Mining | Pit Design tab, in the Build group: Click Add Constraint | Add Constraint (External) to add selected polygons as an external constraint that will direct the build area to be outside its boundary.

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.

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