File Options Dialog Box
Use this dialog box to control the appearance of the model and the speed of
navigation around it, and also to create and configure links to external
databases.
NOTE Some of the tabs are only available when working with 3D models.
When you modify any of the options in this dialog box, your changes are
saved in the currently opened Autodesk Navisworks file, and apply to this file
only.
Ribbon: Home panel ➤ Project tab ➤ File Options
Menu: Classic user interface: Tools ➤ File Options.
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.
