Parametric Timber Rafter Structural Component

This parametric timber rafter Revit family provides a flexible structural component with adjustable pitch and extrusion height settings. The component is a simple, extruded timber rafter designed for structural roof framing. It features clearly defined parameters for the slope angle and the extrusion depth, allowing it to adapt to various roof pitches and beam thicknesses. The geometry is clean and lightweight, focusing on functional representation within a BIM environment. By utilizing reference planes, the family maintains consistent connection points for alignment with other structural elements. This rafter is essentially a basic, highly efficient building block for creating complex pitched roof systems in a Revit project environment, ensuring structural coordination and accurate scheduling.

The download is a 174 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.

Load this family into your project and host it on a reference plane or structural line to define the roof slope. Utilize the type properties to input the required angle and height values, ensuring the geometry updates parametrically. It is recommended to assign a specific structural material parameter to the geometry to control the appearance in both shaded and rendered views. Align the rafter ends with structural walls or ridge beams using the standard Revit modify tools for precise placement.
