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:
Click Options 
on the Standard
toolbar, or click Tools, Options.
On the
System Options tab, click Display/Selection.
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:
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.
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:
-
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.
