Add Constraint (Internal)

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

In Shrinking mode (Pit/Down, Dump/Up), an Internal constraint will place the pit build area inside the constraint where it intersects with any pit lines. No constraint will occur if there is no intersection. 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.
