Autodesk Navisworks uses this hierarchical structure to identify object-specific paths (from the file name down
to a particular object).
By default there are four tabs:
■ Standard. Displays the default tree hierarchy, including all instancing. The contents of this tab can be sorted
alphabetically.
■ Compact. Displays a simplified version of the hierarchy on the Standard tab, omitting various items. You
can customize the level of complexity of this tree in the Options Editor.
■ Properties. Displays the hierarchy based on the items' properties. This enables simple manual searching of
the model by item property.
■ Sets. Displays a list of selection and search sets. If no selection and search sets have been created, this tab is
not shown.
NOTE The list of the items on the Sets tab is exactly the same as the list on the Selection Sets dockable window.
■ Sets. Displays a list of selection and search sets. If no selection and search sets have been created, this tab is
not shown.
Additional customized Selection Tree tabs can be added by using the Autodesk Navisworks API.
Naming of items reflects the names from the original CAD application, wherever possible. There are different
tree icons representing the types of geometry making up the structure of the model. Each of these item types
can be marked as hidden (gray), unhidden (dark blue) or required (red).
NOTE If a group is marked as hidden or required, then all instances of that group are marked as hidden or required.
If you want to operate on a single occurrence of an item, then you should mark the instanced group (the level above,
or the “parent”, in the hierarchy) hidden or required.
