Inquire Face Curvature
Inquire 
Face (Part Level)
Use this command to inquire the curvature
of a face. You are prompted for a base surface, a point on the surface,
and a point which determines the direction to slice the surface for curvature
calculations.
Select a face to inquire.
Specify the point on the face to inquire.
Specify the direction point.
The Inquire Face Curvature Form appears which shows the max/min curvature and the max/min radius of curvature at the selected point. The form also shows the curvature, radius of curvature, and center of circle of curvature, in the direction of the second point. This information is echoed dynamically.
Two line segments are also echoed graphically. One is a line segment connecting the selected face point to its center of circle of curvature. The other is line segment along the tangent plane in the direction of the second point.
