Model Tree overview
The Model Tree appears in the navigation pane on the left side of the work area. You can also open the Model Tree
by clicking the Toggle Model Tree button
and choosing Show Model Tree.
Note: Using the Model Tree requires version 7.0.7 or later of either Acrobat or Adobe Reader. Users with earlier versions
can interact with 3D models but not with the Model Tree.
The Model Tree has three panes, each of which displays a specific type of information or controls.
The topmost pane shows the tree structure of the 3D object. For example, a 3D object depicting a
Structure pane
car may have separate groups of objects (called nodes) for the chassis, engine, and wheels. In this pane, you can move
through the hierarchy and select, isolate, or hide various parts.
Product Manufacturing Information (PMI) appears as a group of items on the same hierarchical level as its related
object or assembly.
