Structural Rebar in Revit Building?

[truevis]

I've noticed that one of the schedules available is "Structural Rebar" -- yet I see no rebar objects available. How can one use the "Rebar Schedule"?

I'm guessing the answer is to use a project from Revit Structure, but that's a separate program.

It might be for Revit structure use when it attached to Revit Building.
