Is wood framing a Revit feature?

This is my first live Revit project and I'd been working under the assumption that the "Basic Roof" family had rafter information that could be displayed in a framing plan. So, "Wood Rafter 8" " could be made to display its rafters. But, searching around it's looking like that's not true and I'd need to get a Revit extension for automatic roof framing. Can someone confirm?
