Adjust Scene Rendering During Navigation
Your models can range in size from small models to complex supermodels.
As you navigate a scene in real time, Autodesk Navisworks automatically
calculates which items to render first, based on the size of items, distance from
the camera, and the specified frame rate. This customizable frame rate is
guaranteed by default, but can be turned off, if necessary. Items that Autodesk
Navisworks does not have time to render are dropped out. These dropped
items are rendered when navigation stops.
The amount of drop-out depends on several factors, such as your hardware
performance (graphics card and driver), the size of the Scene View, and the
size of the model. When working with truly large supermodels in Autodesk
Navisworks, you will require a sufficient amount of RAM to load and review
the data.
Autodesk Navisworks employs JetStream technology which optimizes the
usage of the available RAM. Before running out of memory, Autodesk
Navisworks pages unnecessary data to the hard disk, freeing up space for
loading to continue. JetStream technology also enables you to start navigating
the supermodel, before it has been completely loaded into memory. Autodesk
Navisworks is large address aware, and utilizes any additional memory
assignment following the 3GB switch available on Windows XP systems.
TIP You can reduce the amount of drop-out during navigation by reducing frame
rate, or switching off the Guarantee Frame Rate option.
