Backface Removal

Hides backfacing polygons.

For parts other than solids, the surface normals of exposed polygons may be pointing away from you (backfacing). Because you cannot see the surfaces of parts that are facing away from you, backfacing polygons are not drawn.

Draw Trihedron

Displays the 3-D coordinate system for the model in the Viewing window. Use the trihedron to understand the orientation of the 3-D model.

Two-Sided Lighting

Lights both faces (or sides) of polygons in your 3-D model view.

View Interpolation

When you return to snapshots of 3-D models, changes the view slowly, as if you are watching the model as you move to another position.

Ambient Light Factor

Adjusts the ambient light that illuminates your model. You can type a value between 0 and 1. The change may be subtle.

Set as Default

Sets the specified ambient light factor as the default value.

Antialiasing

Removes the jagged appearance from the angular edges of parts. When no antialiasing is applied, view shading will complete faster.

No. of Samples

Specifies the level of antialiasing.

Selection

Style

Indicate parts that are selected in the Viewing window by changing the Material color or by enclosing the parts in a Bounding box.

Set as Default

Sets the selected style as the default value.

Color

Sets the color of the material or bounding box that indicate part selection.

Set as Default

Sets the selected color as the default value.

Perspective Field of View

Changes the field of view for the 3-D model.

The range of the Perspective Field of View slider is from 0 degrees (Narrow) to 180 degrees (Wide). Typical settings are 8 to 60 degrees. The default setting is 28.0 degrees.

Degrees

Specifies, in degrees, the field of view for the 3D model.

Dynamically Update

Redraws the model as you move the Perspective Field of View slider. Clears the option to redraw the model only when you click Apply or OK.

Reset

Resets the perspective field of view to the default value.
