This command reports and labels the slope between two points or
at points on a surface model (triangulation or grid). The Input
Method for Points prompts you to pick two points and
calculates the slope between these points. The points can be either
picked in the drawing or entered by point number from the current
coordinate file. The Input Method for Surface Triangles
creates a label at center of each triangle face in the surface
which can work well on grid files but is typically too much
information for triangulated surface files. The Input Method for
Pick on Surface prompts to pick the points where to
calculate the slope. For the Pick method, the Define Slope setting
allows a couple ways to pick. The At Single Point option
calculates the slope from the surface model at the point. The
Between Two Points method calculates the slope using the
surface model elevations at two picked points and the horizontal
distance between these points. As the crosshairs are moved across
the surface, the slope at the current position is displayed in a
floating dialog box.
