Polyline

The Polyline tool is used to select part of a bench to create a polyline constraint in your design.

On the Mining | Pit Design (Dynamic) tab, in the Variable Constraint group: : Click Polyline to interactively select part of the bench to create a polyline constraint in your pit design.

The polyline variable constraint is different from the Polygon Zone in that it will not extrude up/down (beyond a small amount). Instead it will extrude left and right (into the pit void, and into the pit wall) so that any vertical shifting of the actual pit strings is accounted for.

When you click the Polyline tool, you will be prompted to select the bench polyline in your design:

Select the part of the bench you want to use to create the polyline constraint and click Accept.

The newly created polyline will be listed in the Variable Constraints grid and you can modify the details of the polyline in the Polyline Constraint form, opened from the More button:

With the polyline selected in the pit design, the Properties pane displays Data and Display properties for the constraint:

You can make changes to the polyline constraint directly in the Properties pane where applicable.
