This command creates slope grading from selected building pads, it is possible to define the angle and the number of iteration points by each segment.
Max Distance Between Points: Along the Pad Edges, this will be the maximum distance between each point. The less the distance, the more points will be created.
Max Slope Angle: The maximum slope of the Grading. The more slope the more close the points will be from the pad.
Multiple Pads: If this option is checked, Onbox will continue to prompt for selecting more Pads until you hit Esc.
