Dir

The Dir command displays and edits an object's normal direction.

Closed polysurfaces, surfaces, and lightweight extrusion objects cannot have their normal direction facing toward the interior of the object.

Note

• The colors of the surface direction arrows match the X/Y/Z axis lines set in Appearance: Colors Options.
• The normal direction arrow color is controlled by the Tracking lines setting in Appearance: Colors Options.
• The size of the arrows is controlled by the Direction arrow icon setting in Appearance Options.

The ShowDir command opens the Direction Analysis control and displays the direction of curves, surfaces, and polysurfaces.
