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
Click Options on the Standard
toolbar, or click Tools, Options.
System Options tab, click Display/Selection.
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
To render curved surfaces in colors:
on the View toolbar, or click View,
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.
To remove the color, clear View,
To change the
values for the color scale for displaying curvature, see Curvature Options.
To render an individual model face in
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.

Model with color applied to selected
curved surfaces (zero curvature is black)
To remove the color, right-click the model face
and clear Curvature.
