There are two types of options: File Options and Global Options.
File Options
For each Autodesk Navisworks file (NWF and NWD), you can adjust the model appearance and the speed of navigation around it. Viewing options are stored with Autodesk Navisworks files (NWF or NWD), and reloaded each time you open these files.
Global Options
Global options are set for all Autodesk Navisworks sessions. The options are grouped together, and presented in a tree structure, making it quicker to find and change them.
Global options can be exported and imported, making it quick and easy for project managers, or systems administrators, to ensure the Autodesk Navisworks settings on all machines are identical. Once exported, these settings can be shared across an entire project site, or across a specific project group depending on the required level of granularity. To do this, you need to set up the Project Directory and the Site Directory. Autodesk Navisworks examines the current user profile and the all users profile on the local machine, and then checks the settings in the Project Directory and the Site Directory. The files in the Project Directory take precedence. When you configure global options, you can lock some of the options to prevent users from editing them later on local machines.
