What should be the radius of curvature for each surface yahoo

Curve curvature is calculated in only one direction U or V, or a section across a surface and is displayed along a curve. Surface curvature is calculated across both surface directions, and is displayed as a continuous color plot across the area of the surface.

In the illustration below, both curve curvature comb plots and a surface curvature color map are applied to the surfaces, so that you can see how the two are related:. Surface Curvature is complex to use and interpret, because there are two directions on a surface, which may have very different curvatures.

So each point on a surface can have two different curvature values, depending on which direction you choose to evaluate:. Because of this complexity, there are many different types of curvature that can be calculated for a surface:. In the Diagnostic Shade panel, firstly choose the Type of Curvature Evaluation, and then adjust the scale to suit the model. You may get very different results depending on which calculation you choose, so it's important to choose carefully to investigate the surface correctly:.
