Curvature

You can display a part or assembly with the surfaces rendered in different colors according to the local radius of curvature. Curvature is defined as the reciprocal of the radius (1/radius), in current model units. By default, the greatest curvature value displayed is 1.0000, and the smallest value is 0.0010.

As the radius of curvature decreases, the curvature value increases, and the corresponding color changes from black (0.0010), through blue, green, and red (1.0000).

As the radius of curvature increases, the curvature value decreases. A planar surface has a curvature value of zero because the radii of flat faces are infinite.

When the Curvature tool is active, you can also display the values for curvature and radius.

To display curvature and radius values:

  1. Click Options on the Standard toolbar, or click Tools, Options.

  2. On the System Options tab, click Display/Selection.

  3. Select Dynamic highlight from graphics view, then click OK.

Now when the Curvature tool is active, the curvature and radius values display beside the pointer when you point to a model surface or a sketch entity (such as a spline or curve).

To render curved surfaces in colors:

  1. Click Curvature on the View toolbar, or click View, Display, Curvature.

    The curvature of the model is displayed in color. When you point to a model surface, a spline, or a curve, the curvature value and the radius of curvature are displayed beside the pointer.

  1. To remove the color, clear View, Display, Curvature.

To change the values for the color scale for displaying curvature, see Curvature Options.

To render an individual model face in colors:

  1. Right-click the model face and select Curvature.

    The curvature of the selected face is displayed. When you point to the model face, the curvature value and the radius of curvature are shown beside the pointer.

  2. To remove the color, right-click the model face and clear Curvature.
