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. ■ 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. This enables performance to be prioritized over structure/properties and has the added benefit of improving streaming by cutting down the logical structure. NOTE Although Autodesk Navisworks tries to collapse items to the fewest number possible, it may be necessary to prevent collapsing in some cases to preserve model fidelity. For example, if an item has properties or materials unique to itself, then collapsing would endanger this information, and therefore it will not be collapsed. Close NWC/NWD files on Load Indicates whether NWC and NWD files are closed once they've been loaded into memory. When you open NWC/NWD files, Autodesk Navisworks locks them for editing. By selecting this check box, you instruct Autodesk Navisworks to close NWC or NWD files as soon as they've been loaded into memory. This means that the files can be opened and edited by other users while you are viewing them. Create Parametric Primitives Select this check box to enable creation of parametric models (models described by formulae not vertices). Using this option allows you to get better looking visuals, faster rendering, smaller memory footprint (especially, when loading DGN and RVM files with significant amounts of parametric data that no longer need to be converted into vertices in Autodesk Navisworks). NOTE Modifying this option takes effect when you next load or refresh file. Create Presenter Materials Select this check box to enable creation of Presenter materials when NWC files are loaded. Clearing this check box turns off creation of Presenter materials. Use this option if you've only got Autodesk Navisworks Review installed. Temporary File Location Auto Indicates whether Autodesk Navisworks automatically selects your user Temp folder. Location Click to open the Browse for Folder dialog box, and select the desired Temp folder. 408 | Chapter 17 Autodesk Navisworks Reference
