Primary to Secondary Drainage Box Detail Component

This Revit family provides a technical detail component for a primary to secondary drainage box, ideal for roof drainage documentation. The component represents a standard primary to secondary drainage box assembly, commonly utilised in flat roof drainage systems to manage overflow and water discharge. The geometry features a square catchment box connected to a vertical downpipe section, rendered as a clean line-based detail component. It is designed to be placed within drafting views or detail sections in Revit, providing a consistent graphical representation of the drainage junction. The line work is clear and structured, facilitating easy integration into construction documentation sets where precise detailing of roof water management is required by engineers.

The download is a 389 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Users should load this RFA file directly into their Revit project as a detail component. Once loaded, it can be placed into any 2D drafting view or detail section. It is intended for use in construction documentation, where it can be annotated and dimensioned to illustrate specific drainage connections. Because it is a detail component, it does not occupy 3D space, allowing for efficient placement without affecting the model's performance or requiring complex 3D coordination.

This component is essential for architects and MEP engineers working on flat roof projects, particularly in residential and industrial building types. It is most effective during the technical design and construction documentation stages, where detail drawings of drainage systems are mandatory. Professionals can use this to clarify junction details in roof plans or section drawings, ensuring that site teams understand the primary and secondary drainage paths. It pairs well with other standard roof drainage and plumbing detail components found in technical libraries.
