Sidewalls

On the Mining | Pit Design tab, in the Generate group: Click Sidewalls to generate a polygon enclosing an area within a specified distance of the selected string.

If you have not already selected the string you want to generate the sidewall for, you will prompted to do so by the Selection Assistant. A form is then displayed, prompting you to enter the offset distance for the left and right walls.

When you click OK, a polygon is formed by joining the left and right walls with two lines perpendicular to the centre line string.
