You can use callouts to create specific, enlarged views of the building model. Typically, you detail components to a detail to call out items that are not included as part of the building model, like bolts and connectors, or detailed brick hatches. You can also use callouts to generate sections or elevations of an existing section or elevation. For example, you could create a section of the building model, and then create an enlarged detail from part of the section. To that detail, you could then add detail components for the construction document.
