Expand String

On the Mining | Pit Design (Manual) tab, in the Generate Pit Contours group: Click the Expand String tool to use the Berm width and Expand settings in the Pit Design form to expand the selected string.

(This tool differs from the Expand String tool on the the Design tab, in the Editing group, which expands the current string in an inwards or outwards direction based upon a specified expansion distance.)
