About Working with Annotation Features
Annotation features do not create any geometry, therefore, you can not select them on the screen, like other features. The only way to select the Annotation features is from the Model Tree. Therefore, it is very important that the Annotation features are displayed in the Model Tree.
In Part mode, the Annotation features are listed in the Model Tree by default, like any other type of features. In Assembly mode, they are not listed by default. Use the configuration option mdl_tree_cfg_file, or follow the procedure for displaying annotation in the Model Tree.
When you work with Annotation features, it is helpful to display the Annotation Elements and individual annotation in the Model tree as well. When you display annotation in the Model Tree:
You can expand an Annotation feature name, to see all the Annotation Elements listed underneath. This makes it easy to see the structure of an Annotation feature, and to modify the Annotation Elements.
All the independent annotation items (such as symbols, reference dimensions, and so on), that are not included in Annotation features, are listed at the top of the tree, immediately below the part or assembly name. Notes are listed below its parent (assembly, part, or feature). This makes it easy to see which annotation items are independent. Once an annotation item is included in an Annotation feature, it is consumed by the Annotation Element and is not listed separately in the Model Tree.
Once you set up the proper display of Annotation features in the Model Tree, you can work with them like with other Creo Parametric features: edit definition or references, suppress, resume, delete, and so on. The topics in this section are discussing the specific aspects of working with Annotation features.
