• Railings: When you create a railing in an Autodesk Revit 2013 project, new railing types are available that include top rail and handrail properties. When you upgrade a project, if the new rail (top rail and handrail) properties do not display in the railing Type Property dialog, duplicate the existing railing type, and the new rail properties will be available in the duplicated type.
