To render parametric primitives
NOTE: Modifying this option requires a restart of Autodesk Navisworks to
take effect.
1 Click the application button
➤ Options.
2 In the Options Editor, expand the Interface node, and click the
Display option.
3 On the Display page, Primitives area, select the Enable Parametric
Primitives check box. The level of detail changes during navigation
depending on the distance from the camera.
If you want to use the default representations of primitives, clear this
check box. The level of detail stays the same during navigation.
Click OK.
Accelerate Display Performance
If your video card supports OpenGL, you can improve the graphical
performance by turning on hardware acceleration and occlusion culling.
Using the hardware acceleration usually gives you better and faster rendering.
However, some graphics cards may not function well in this mode in which
case switching this option off is recommended.
Occlusion culling can significantly improve performance in situations when
much of the model is not visible. For example, when you walk down the
corridor of a building, the walls occlude most geometry outside the corridor.
Other rooms are only visible through doorways or windows. Turning on
occlusion culling dramatically reduces the rendering load in such cases.
