Iso-angle projects onto the surfaces from a certain angle, and creates shaded bands and/or lines where the surface is at right angles to the projection direction.

Create iso-angle display shading/lines

1. Pick the surfaces.
2. Choose Evaluate > IsoAngle .
3. Choose whether to shade the surfaces and/or create lines.
4. Choose whether to show a single or multiple bands.
5. Use the manipulator to set the direction of projection.

   If the manipulator is not visible, click the Show Manipulator button.

   Tip

   It is often helpful to use multiple bands as you position the manipulator to give you more feedback, then switch to fewer or a single band.

The iso-angle shader is now also available from the Diagnostic Shading Panel. Some option are provided in the panel. Others (such as number of bands and vector direction) must be accessed from the Evaluate > IsoAngle option box.
