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.
■ 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.
Naming of items reflects the names from the original CAD application, wherever possible. You can copy and
paste names from the Selection Tree. To do this, right-click an item in the Selection Tree, and click Copy Name
on the context menu. Alternatively, you can click an item in the Selection Tree, and press CTRL + C. The name
is now copied to the clipboard.
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.
To toggle the Selection Tree
■ Click Home tab ➤ Select & Search panel ➤ Selection Tree .
Menu: Classic user interface: View ➤ Control Bars ➤ Selection Tree
Command entry: CTRL + F12
To use the Selection Tree to select objects
1 Open the Selection Tree, and click the Standard tab.
2 Click an object in the Selection tree to select the corresponding geometry in the Scene View.
NOTE When you select an item in the tree, individual geometry or a group of geometry is selected in the Scene
View depending on chosen selection resolution.
3 To select several items at the same time, use the SHIFT and CTRL keys. CTRL allows multiple selection item
by item, and SHIFT allows multiple selection between the first and last items selected.
4 To remove selection from an object in the Selection Tree press ESC.
