Terms and Concepts

Term/Concept Definition
Model Elements Used to define the geometry of the model. Once placed, model elements display instantly in all views. In most cases the model elements represent physical elements such as walls, windows, and doors. All of the categories for model elements are found on the Model tab of the Visibility/Graphic Overrides dialog and the Object Styles dialog.
Annotation Elements View-specific elements that are used to
  • document the model, for example, dimensions, tags, or notes.
  • add details to a view not generated by model geometry, for example, lines and detail components.

Large-scale details such as a wall foundation or parapet will use annotation and detail elements to fully illustrate the condition.

Model Views Used to see the model from different viewpoints. Each view is controlled independently. When a model element is placed in a view, this element will be visible in all other views, according to the visibility and graphics settings for each view. Annotation elements placed in a view will only be visible in the view they are placed in.
Visibility Override Method used to change the visibility status and graphic appearance of individual elements. Select the element in the drawing area, right-click, and apply a visibility override from the context menu. The visibility override has priority over the visibility settings applied to the category in the view. This override allows you to display individual elements as needed in a view. For example, a single door could be set to display as "halftone" while all other doors are displayed as normal.

Transcript

This video demonstrates how to place model and annotation elements in project views. It also explains the rules that govern their visibility.

When you place a table component in the Furniture Plan view, it is also visible in the Floor Plan view. The model elements you add to the project are visible in all views of the project instantly.

By contrast, when you use the Text Note tool to add a note to the table in the Furniture Plan view, the note does not appear in the Floor Plan view. The text is an annotation element and is visible only in the view in which you place it.

Dimension strings and object tags are also annotation elements, so they are view-specific. Just like annotation elements, detail elements such as lines and detail components are view-specific. When you add detail elements to model geometry to enhance or clarify the view, they are visible only in the view in which you placed them.

As a final example, we will go to the Annotation tab of the ribbon ,and add a CMU repeating detail component to the wall in the foundation detail view. As you would expect, the CMU is not modeled. Instead, it is added as a view-specific element to enhance the model geometry in the view. Additional detail elements, which are not modeled in 3D, are added to the foundation detail view to further document the model.
