This command reports and labels the slope of a triangulation or
grid surface model. The Link To Surface option will update
the slope label when the triangulation surface model is modified.
The Position Method for Surface Points creates a
label at each data point in the surface which can work well on grid
files but is typically too much information for triangulated
surface files. The Position Method for Screen Pick prompts
to pick the points where to calculate the slope. For the Screen
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.
