Distance Specifies the farthest distance between the camera and the near clipping plane position in constrained
mode.
Specifies the exact distance between the camera and the near clipping plane position in fixed mode.
NOTE Nothing is drawn between the camera and the near clipping plane; when you override automatic mode, make
this value small enough to display your data. Also, overriding automatic mode with values under 1 can produce
unpredictable results.
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:
■ On - turns on backface culling for all objects.
■ Off - turns off backface culling
■ Solid - turns on backface culling for solid objects only. This is the default option.
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 Defaults button.
Orientation Tab
Use this tab to adjust the real-world orientation of your model.
Up
X, Y, Z Specify the X, Y, and Z coordinate values. By default, Autodesk Navisworks takes the positive Z-axis as
Up.
North
X, Y, Z Specify the X, Y, and Z coordinate values. By default, Autodesk Navisworks takes the positive Y-axis as
North.
TIP If you want to restore the default values, click the Defaults button.
Speed Tab
Use this tab to adjust the frame rate speed to reduce the amount of drop-out during navigation.
TIP If this does not improve navigation, try switching off the Guarantee Frame Rate option.
Frame Rate Specifies the number of frames per second (FPS) that are rendered in the Scene View.
