You can display a part or assembly with the surfaces rendered in different colors according to the local radius of curvature.
Curvature is defined as the reciprocal of the radius (1/radius), in current model units. By default, the greatest curvature value displayed is 1.0000, and the smallest value is 0.0010.
As the radius of curvature decreases, the curvature value increases, and the corresponding color changes from black (0.0010), through blue, green, and red (1.0000).
As the radius of curvature increases, the curvature value decreases. A planar surface has a curvature value of zero because the radii of flat faces are infinite.
