Allow Rebar to be Used Inside Loadable Families as Parametric Reinforcement I would like to propose a new capability in Revit that allows Rebar to be used inside Loadable Families as fully parametric and interactive reinforcement. For example, a structural column family could contain its reinforcement definition. A column type could have 4 main bars of 16 mm diameter, 8 mm stirrups, a defined spacing, anchorage length, and stirrup shape. These reinforcement elements should remain native Rebar elements and should be controlled by family parameters. If the column dimensions or family parameters change, the reinforcement should automatically update its position, distribution, and geometry. I tried to achieve this workflow using Nested Families, but Rebar cannot currently be used as a normal Nested Family component. This limitation forces structural modelers to work in multiple stages. First they model the structural element, then they model the reinforcement, and later they modify the reinforcement whenever the structural element changes. With this capability, the structural element and its reinforcement could be modeled as one intelligent parametric family. For example, a reinforced column family could contain the column geometry and its reinforcement rules. Changing the column height would automatically update the reinforcement distribution. Changing the column width or depth would automatically update the stirrup geometry and reinforcement constraints. The main benefit would be reducing repetitive modeling work and saving significant modeling time. Instead of modeling the structural element first and reinforcement as a separate process, users could define the reinforcement once and reuse the same reinforced family throughout the project. This would be especially useful for columns, beams, walls, foundations, footings, pile caps, and repetitive structural systems. The reinforcement should remain native Rebar and continue to support scheduling, quantities, documentation, visibility, clash detection, and project coordination. This feature would enable a new workflow in Revit: Parametric Reinforced Families. Model once, define reinforcement rules, and reuse everywhere.
