  Curve Curvature Analysis  

Display Curve Curvature:  Displays a set of lines representing the curvature of the surface.  The length of the lines is inversely proportional to the radius of curvature.
Type:  Choose the type of curve display (Iso Curve - curvature along iso-curves as specified in the viewport display settings, Natural - natural surface curvature, Min - minimum surface curvature, Max - maximum surface curvature)
Scale:  Define the radius of curvature for the selected arc
Density:  Determines the curve display density

  Surface Curvature Analysis  

Display Surface Curvature:  Displays a colored mesh representing various curvature properties of the mesh.  This will show areas of high curvature or inflection and may indicate that the surface needs further adjustment or redesign.
Type:  Choose the surface analysis display type (Gaussian - product of principle curvatures , Mean = mean of principle curvatures, Min = minimum principle curvature, Max = maximum principle curvature)
Std Dev. Multiples: Used to control the mapping of the colors onto the mesh.    
Use Min/Max Range:  Turn this option on to show a colored display showing the range of values across the surface.
Min:  The maximum value range (surface areas where curvature exceeds this maximum value will display in red).  Note, to use Min/Max ranges, make sure to check the "Use Min/Max Range" check box.
Max:  The maximum value range (surface areas where curvature exceeds this maximum value will display in red).
