You can display curvature combs on model surfaces to analyze how adjacent surfaces join and transition.
The Surface Curvature Combs tool evaluates curvature quality and smoothness. It displays U and V mapping lines in a graphical display across face boundaries. The tool looks for curvature constraints and extends curvature combs across adjacent faces. The length of each spine on the comb is proportional to the amount of curvature at the point. The spines are perpendicular to the surface.
