Use Viewpoint Linear Speed When this check box is selected, the Walk tool will respect the Viewpoint Linear
Speed setting. In this case, the Walk speed slider will act like a multiplier.
When this check box is clear, the Walk tool will work independently of the Viewpoint Linear Speed setting,
using a fixed value set with the slider.
Walk Speed Sets the speed of the Walk tool from 0.1 (very slow) to 10 (very fast).
Zoom Tool
Enable Single-Click Incremental Zoom In When this check box is selected, single clicking over the Zoom
wedge increases the magnification of the model. When this check box is clear, nothing happens when you single
click over the Zoom wedge.
Orbit Tool
Keep Scene Upright When this check box is selected, the Orbit tool behaves similarly to the classic Orbit mode,
with orbiting constrained along the XY axis and in the Z direction.
When this check box is clear, the Orbit tool behaves similarly to the classic Examine mode, and you can roll the
model around the pivot point.
Enable Selection Sensitivity When this check box is selected, the objects selected before the Orbit tool are used
to calculate the pivot point to use for orbiting. The pivot point is calculated based on the center of the extents
of the selected objects.
User Interface Page
Use the options on this page to choose the user interface (standard or classic), and select the color theme.
User Interface Choose between the following options:
■ Classic. Switches over to the classic Autodesk Navisworks interface with old-style menu and toolbars.
■ Standard. Switches over to the new interface with a ribbon tool palette. This is the default option.
Theme Use the drop-down list to apply one of the preset interface themes.
Model Node
Use the settings in this node to optimize Autodesk Navisworks performance, and customize parameters for NWD
and NWC files.
TIP If you want to restore the default values, click the Defaults button.
Performance Page

Memory Limit
Auto Indicates whether Autodesk Navisworks automatically determines the maximum memory that can be used.
Selecting this check box sets the memory limit to the lowest of your available physical memory or address space,
less that required for your operating system.
Limit (MB) Specifies the maximum memory that Autodesk Navisworks can use.
Merge Duplicates
These options improve performance by multiply instancing matching items. Rather than storing every item in
memory, if any items are the same, Autodesk Navisworks can store one instance of them and 'copy' that instance
into other positions. This is of particular benefit on larger models, where there are significant numbers of these
duplicate geometries.
On Convert Select this check box to merge duplicates when a CAD file is converted into the Autodesk Navisworks
format.
