Revit 2011 Creates Callouts and Drafting Views

Callouts
There are two types of callouts: Detail and Floor Plan.

Although Detail callouts may look like Detail sections graphically, they’re not visible inside other perpendicular views. So a callout created in plan view will not be visible in elevations or sections like a Detail section.

It’s probably best to think of a Detail callout as an enlarged view. Its Far Clip settings are by default the same as the parent view.

You can think of a Floor Plan callout as another plan view but with associated callout graphics. Floor Plan callouts also have all the same view controls as a regular plan view, such as Depth Clipping and View Range.

Take a moment to note the line and control arrows around the border of the view. By modifying the location of these arrows, you’re modifying the extents of the view. Of course, more than plan views can have their extents modified; elevations, sections, and callouts can all have their view extents modified in the same way.

Drafting Views
Drafting views give you the ability to draw without first creating a reference to something in your project. They may contain Detail and Repeating Detail components, as well as all the annotation and documentation tools that Revit has to offer. Drafting views are great for drafting standard or analytic conditions that don’t require an actual geometric underlay.
And once you’ve created a drafting view, you may refer to this view when creating an elevation, section, detail, and so on that would normally rely on an actual view of the model. As you start to create a standard project view,

simply select the Reference Other View option and then you’ll be allowed to select a reference view from all the other like views in your project, as well as any drafting views.
