About the Mechanism Tree
After you open a mechanism model or create a new one, click > 
Mechanism. The Mechanism Tree appears underneath the general Model Tree. All the rigid bodies, connections, motors, analyses, playbacks, and other simulation entities associated with the model appear on the tree. Right-click entities in the Mechanism Tree or on the model to access shortcut menus.

When you make a selection in the Mechanism Tree, the selected entity is highlighted on your model. When you select Gravity, the ground body LCS is highlighted and an arrow points in the direction of the gravitational acceleration vector.
 | When working with large models with several connections or motors, you can often find a specific connection or motor in the Mechanism Tree more easily than on the model. |
Using Shortcut Menus from the Mechanism Tree
The table below shows the commands that appear on a shortcut menu when you right-click an entity in the Mechanism Tree. Similar menus are available when you right-click entities on your model. Starred items in the table are visible in the Mechanism Tree only if you have a Mechanism Dynamics license.
