Fill In Detail Indicates whether Autodesk Navisworks fills in any discarded
detail when navigation has stopped.
Graphics System
Auto-Select Autodesk Navisworks supports two graphics systems: Presenter
Graphics and Autodesk Graphics. By default, this check box is selected and
Autodesk Navisworks controls which graphics system to use. Clear this check
box if you want to select the system yourself. This enables the System
drop-down box.
Hardware Acceleration Select this check box to utilize any available OpenGL
hardware acceleration on your video card.
If your video card drivers do not function well with Autodesk Navisworks,
clear this check box.
NOTE If your video card does not support OpenGL hardware acceleration, this
check box is not available.
System This drop-down box is available when you clear the Auto-Select
check box. Select from the following options:
Presenter - supports the display of Presenter materials and uses Hardware
or Software OpenGL.
Autodesk - supports the display of Autodesk materials and uses Direct3D
or Hardware OpenGL.
NOTE 3D models can use either graphics system, Presenter system is the default
option. 2D sheets can only use Autodesk Graphics, and will not render without a
Direct 3D/OpenGL supported graphics card.
Occlusion Culling Select this check box to enable occlusion culling. This
means that Autodesk Navisworks only draws visible objects and ignores any
objects located behind other objects.
Selecting this check box improves the display performance when much of the
model is not visible. For example, when youre 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.
