Culling Tab
Use this tab to adjust geometry culling in the opened Autodesk Navisworks
file.
NOTE The Clipping Planes and Backface options are only available for 3D models.
Area
Enable Specifies whether or not area culling is used.
Number of Pixels Below Which Objects Are Culled Specifies a value for the
screen area in pixels below which objects are culled. For example, setting the
value to 100 pixels means that any object within the model that would be
drawn less than 10x10 pixels in size are discarded.
Clipping Planes
Near
Automatic Select this radio button to make Autodesk Navisworks automatically
control the near clip plane position to give you the best view of the model.
The Distance box becomes unavailable.
Constrained Select this radio button to constrain the near 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 near clip plane position as necessary.
Fixed Select this radio button to set the near clipping plane to the value
provided in the Distance box.
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.
