The Model Tree displays the features in their collapsed state after their creation or redefinition. The embedded datum features that are referenced by a feature are displayed as sub-nodes of the feature when you expand the feature. They are displayed in their order of creation with feature numbers that are lower than the number of the main feature in which they are embedded. The asynchronous datum features that are not referenced by the feature are displayed above the corresponding feature on the Model Tree.

During the creation or the redefinition of the feature, the asynchronous datum features are displayed as nodes above the main feature so that you can use them as references for creating new asynchronous datums.

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.

If an embedded datum is used as a reference by another embedded datum in the same feature, the Model Tree displays a flat structure of the feature. The second-level embedded datum reference is also displayed as a sub-node of the feature.
