Selecting this check box improves the display performance when much of the
model is not visible. For example, when you’re walking down the corridor of
a building.
IMPORTANT Occlusion culling can only be used on a machine with an OpenGL
1.5 compliant graphics card. Also, occlusion culling is not used in a 2D workspace.
Heads Up
XYZ Axes Indicates whether the XYZ Axes indicator is displayed in the Scene
View.
Show Position Indicates whether the Position Readout is displayed in the
Scene View.
Primitives
Point Size Enter a number from 1 through 9 to set the size (in pixels) of points
drawn in the Scene View.
Line Size Enter a number from 1 through 9 to set the width (in pixels) of lines
drawn in the Scene View.
Snap Size Enter a number from 1 through 9 to set the size (in pixels) of snap
points drawn in the Scene View.
Enable Parametric Primitives Indicates whether Autodesk Navisworks
dynamically renders parametric primitives during interactive navigation.
Selecting this check box means the level of detail changes during navigation
depending on the distance from the camera.
Clear this check box to use the default representations of primitives; the level
of detail stays the same during navigation.
Transparency
Interactive Transparency Select this check box to render transparent items
dynamically during interactive navigation.
By default, this check box is clear, therefore, transparent items are only drawn
when interaction has stopped.
NOTE If your video card does not support hardware accelerated OpenGL, selecting
this check box can affect display performance.
