Pit Layout by Width

This command creates closed polylines that represent pit inclusion areas for Surface Reserves and Timing. The pit polylines are created by advancing a baseline polyline by a fixed pit width. The sides and end of the pit polylines are defined by the minable boundary polyline. This polyline should be open at the end of the baseline polyline. Be sure to create the baseline polyline longer than the minable boundary so that the program can always find the intersection of the advancing baseline with the minable boundary. There is an option to automatically assign pit and site names to the polylines. The name of the first pit is set in the dialog shown below. The next pits will be named by incrementing the pit name by one. There is an option to prompt for each pit width or use the same width for all the pits.
