The Model Tree is a list of every feature in a part file including the datums and coordinate system. In a part file, the Model Tree shows the part file names and each feature in the part below it. In an assembly file, the Model Tree shows the assembly file names and the included part files beneath it.

The model structure is displayed in a hierarchical (tree) format with the root object (the current part or assembly) at the top of its tree and the subordinate objects (parts or features) below. If you have multiple Creo Parametric windows open, the Model Tree contents reflect the file in the current window.

The Model Tree lists only the related feature- and part-level objects in a current file and does not list the entities such as edges, surfaces, curves, and so forth that comprise the features.

Each Model Tree item contains an icon that reflects its object type, for example, hidden, assembly, part, feature, or datum plane (also a feature). The icon can also show the display or regeneration status for a feature, part, or assembly, for example, suppressed or unregenerated.

You can save all of the information in the Model Tree as a text (.txt) file. Subsequently, you can print the file, import it into a text editor and format it for review, import it into Microsoft Excel, and apply scripts to it. You can add columns to the Model Tree that display selected information about the model.

Selection in the Model Tree is object-action oriented; you select objects in the Model Tree without first specifying what you intend to do with them. You can select components, parts, or features using the Model Tree. You cannot select the individual geometry that makes up a feature (entities). To select an entity, you must select it in the graphics window.

By default, the Model Tree displays each embedded datum as a feature subnode in the creation order that is the last created item is displayed first. For a feature, the display of embedded datums and other subnodes on the Model Tree is in the order of sketch, annotation, embedded datums, and transformed or patterned features. The patterned, mirrored, or moved features are automatically grouped when you embed datum features in them. They are displayed in the Model Tree with labels that include the tool names, such as Patterned Features, Mirrored Features, or Moved Features. The embedded datum features are displayed as sub-nodes of the group header, above all other group members. The asynchronous datums with their respective feature are displayed as a feature subnode on the Model Tree. In the Model Tree using the drag-and-drop technique, you can convert a stand alone datum to an embedded datum and vice versa.
