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
Use the options on this page to optimize Autodesk Navisworks performance.
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.
On Append Select this check box to merge duplicates when a new file is appended to the currently opened
Autodesk Navisworks file.
On Load Select this check box to merge duplicates when a file is loaded into Autodesk Navisworks.
On Save NWF Select this check box to merge duplicates when the current scene is saved in the NWF file format.
On Load
Collapse on Convert Collapses the tree structure on the Selection Tree to the specified level when native CAD
files are converted into Autodesk Navisworks. Select from the following options:
■ None - the tree is fully expanded. Use this option to enable splitting polylines into individual segments when
importing DWGs and DGNs to support multiple clash intersections. For DGN files, you also need to select
File Readers ➤ DGN ➤ Split Lines check box, and deselect File Readers ➤ DGN ➤ Merge Lines and Arcs
check box. For DWG files, you also need to set File Readers ➤ DWG/DXF ➤ Line Processing drop-down to
Separate All Lines.
■ Composite Objects - the tree is collapsed up to the level of composite objects.
■ All Objects - the tree is collapsed up to the level of objects.
■ Layers - the tree is collapsed up to the level of layers.
■ Files - the tree is collapsed up to the level of files.
