Command description:



This command is used to color code mesh triangles according to the slope range they are in. The start and end slope values of the range are specified and a color is chosen for each slope range. The slope representation is done by applying a solid HATCH to each slope zone that is found. A slope zone analysis legend block will be created when this command ends, allowing the user to select the insertion point and scale.
