Evaluate > Min/max curvature

Displays the points with minimum and maximum curvature on a surface or a set of surfaces.

See Show the minimum and maximum curvature on a surface

Mode

Choose whether to compute the curvatures on only Active (picked) objects, or All objects. All is the default.

Curvature Type

Choose how to calculate the curvature values:

Mean: use the average of the two principal curvatures to approximate the average curvature through each point.

Gaussian: use the product of the two principal curvatures.

Principle Minimum/Principle Maximum: use the minimum or maximum curvature values (that is, the curvature of the steepest or flattest curves that pass through each point).

The Mean and Gaussian options are most useful for detecting surface irregularities. The Princ Min/Max options are most useful for finding inflection points.
