Positive Gaussian curvature means that the surface is shaped like a bowl.
Negative Gaussian curvature means the surface is shaped like a saddle (as
shown below). Mean curvature and a zero Gaussian value means that the
surface is flat in at least one direction (planes, cylinders, and cones have zero
Gaussian curvature).
To change the curvature analysis display settings, use the
Curvature tab (page
65) of the
Analysis Options dialog box (page 64).

Summary
The color spectrum shows draft angle changes within a specified range. The
maximum draft angle displays as red, and the minimum draft angle displays
as blue.
