About the Model Tree
The Model Tree is a list of items in the model, in a hierarchical structure, that reflects, relations between the items or their order of regeneration. By default, the Model Tree is in the Creo Parametric main window. If you do not see the Model Tree, click .
Each node in the Model Tree represents an item in the model. Some nodes are containers for other nodes. You can right-click a node to access commands from mini toolbar or shortcut menu. The nodes are collected as references while performing operations such as boolean, split, and so on.
Model Tree Structure
The top node of the Model Tree represents the entire model, and is the part file or top-assembly file that is opened in the active window. The top node contains the following subnodes:
Placement—Appears only in assembly components, containing the sets of placement constraints.
Design items—A folder for materials, quilts, bodies, annotations, and individual custom groups.
Individual feature nodes—Each feature is represented by a node in the tree.
Sections—Dedicated container for section features, located at the end of the feature list.
Footer—Dedicated container for placing features at the end of the feature list.

You cannot reorganize the items in the folders, except for the items in the Custom Groups. For example, you cannot change the order of the bodies in the Bodies folder.
You cannot change the order of the folders. For example, you cannot place the bodies folder before the quilts folder.
The Model Tree does not list geometric entities such as surfaces, edges, and curves.
There is an icon for each Model Tree item that corresponds to its object type, such as assembly, part, body, feature. For some items, a glyph near the icon shows the status of the item, for example, suppressed feature or packaged component.
Splitting the Model Tree
You can split the model tree to work independently with both the trees. When the Model Tree is split, two separate trees appear one below the other, which are no longer synced. For example, the trees have separate search boxes and independent filters. The Model Tree can be split into two trees:
Model Tree— Contains feature list
Design Tree— Contains folders such as Materials, Bodies, Quilts, and Custom Group.
To split the trees, in the Model Tree, click Show , and select the Design Tree check box. By default, the Model Tree appears adjacent to the Design Tree.
Placement of the Trees
You can move the trees, such as Model Tree, Layer Tree, or any other tree, and place it separately anywhere in the graphics window.
To move the tree:
1. If the tree is attached to the borders, place the pointer on the tree icon, and the pointer appears as a four-way dragger.
For a tree that is not attached (floating tree), place the pointer on the title bar of the tree.
2. Left-click and drag the tree. You can now attach the tree to graphic window borders or leave it as floating by releasing the left mouse button.
To reset the tree to its default attached state, right-click on the navigation bar and select the reset option.
You can do the following, in the graphics window and navigation pane:
Snap the trees to the borders.
When you move the tree near to the borders, the blue highlighting indicates the snapping the preview. The tree is snapped to the border based on the preview highlighting. When you resize the graphics window or navigation pane, the snapped trees are resized accordingly.
You can place the trees vertically (one tree below the other tree) or horizontally (one tree next to the other tree).

Click at the bottom of the left pane to hide or show the embedded panes outside the navigation tabs.
Save the locations of the trees. When you change the positions of tress, and close Creo, the next time you open Creo, the trees are in the position you left them.
