Tweak Face Display Options

These display modes can help you see the contours of a face or surface.

Grid	Displays a grid on your face or surface. This is similar to the Grid tool on the Measure tab.
Curvature	Displays a gradient on your face or surface. The curvature with the largest radius is shown in the maximum color. The curvature with the smallest radius, or no radius, is shown in the minimum color. This is similar to the Curvature tool on the Measure tab.
Porcupine	Displays a fringe graph on your face or surface. This display shows you the tangency of your surface at multiple points.
Show Off-Face Control Points	Displays all control points. If this option is not selected, you won't see control points that don't affect the surface.
Show Periodic Seams	Displays the beginning seam of the surface when you are editing periodic faces (cylinders, cones, and other revolved surfaces). This may help you see of the characteristics or behavior of some periodic faces as you edit.
