About Model Notes
Model notes are text strings that you can attach to objects. You can attach any number of notes to any object in your model.
You can use model notes to:
Tell other members of your workgroup how to review or use a model that you have created.
Explain how you approached or solved a design problem when defining the features of a model.
Explain changes that you have made to the features of a model over time.
You can include model notes in Annotation features. This way, you can define a library of company-specific annotation, and then place it in various models, as appropriate.
You can create the following types of notes.
Note not attached to any reference
Note placed on the selected reference
Note with a leader
Note with leader normal to the selected reference
Note with leader tangent to the selected reference
