Far
Automatic Select this radio button to make Autodesk Navisworks automatically
control the far clipping plane position to give you the best view of the model.
The Distance box becomes unavailable.
Constrained Select this radio button to constrain the far clipping plane to
the value set in the Distance box.
Autodesk Navisworks uses the provided value unless doing so affects
performance (for example, makes the whole model invisible), in which case
it adjusts the far clip plane position as necessary.
Fixed Select this radio button to set the far clipping plane to the value provided
in the Distance box.
Distance Specifies the closest distance between the camera and the far clipping
plane position in constrained mode.
Specifies the exact distance between the camera and the far clipping plane
position in fixed mode.
NOTE Nothing is drawn beyond this plane; when you override automatic mode,
make this value large enough to include your data. Additionally, using the ratio
of the far clipping plane to near clipping plane in excess of 10000 can produce
unwanted effects.
Backface
Turns on backface culling for all objects. Select from the following options:
■ Off. Turns off backface culling.
■ Solid. Turns on backface culling for solid objects only. This is the default
option.
■ On. Turns on backface culling for all objects.
TIP If you can see through some objects, or some object parts are missing, turn
off backface culling.
TIP If you want to restore the default values, click the Reset to Defaults button.
Orientation Tab
Use this tab to adjust the real-world orientation of your model.
NOTE This tab is only available for 3D models.
