During the course of a project, you may want to create details in a view that are not directly associated with the model. Rather than create a callout and then add details to it, you may want to create detail conditions where the model is not needed (for example, a carpet-transition detail which shows where carpet switches to tile, or roof-drain details not based on a callout on the roof).
You create this unassociated, view-specific detail in a drafting view. The drafting view is not associated with the model. In a drafting view, you create details at differing view scales (coarse, medium, or fine) and use 2D detailing tools: detail lines, detail regions, detail components, insulation, reference planes, dimensions, symbols, and text. These are the exact same tools used in creating a detail view. However, drafting views do not display any model elements. When you create a drafting view in a project, it is saved with the project.
When using drafting views, consider the following:
