Change the orientation of surfaces

Orient surfaces so they face toward or away from the camera.

This may be necessary before using tools that depend on surface orientation such as Ambient Occlusion, Offset and Parting Line.

Reversing the orientation of a surface does not affect the U or V parametric directions, and preserves construction history.

1. Choose Surface Edit > Orientation > Set Surface Orientation .

   All surfaces in the scene are shaded in blue and yellow.

   

   Surfaces facing toward the camera are shaded in blue; surfaces facing away from the camera are shaded in yellow.

2. To change the orientation of a surface:
   • click the surface with the to orient it toward the camera.
   • click the surface with the (or + ) to orient it away from the camera.
     NoteYou can click anywhere on the surface (not only the wireframe).

   The color of the surface changes immediately.

3. If there are several surfaces to change, draw a pick-box around them (using the appropriate mouse button as described above).

   

   After orienting all the surfaces to face toward the camera, all the surfaces in the scene should be blue.
