Simple Scissor Truss

This simple scissor truss Revit family provides a structural framing component designed to create vaulted ceiling profiles in roofs. The simple scissor truss is a standard structural roof component featuring two primary rafters that intersect at the apex and internal bracing members arranged in a classic scissor configuration. This design allows for a raised ceiling height at the centre of the span, effectively creating a cathedral or vaulted interior space. The geometry is clean and linear, intended for representation in structural framing plans and 3D models. It includes the necessary top chords, bottom chords, and vertical or diagonal web members required to support roof loads while maintaining the characteristic angled profile of a scissor truss system.

The download is a 410 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 can load this RFA file directly into a Revit project as a structural framing family. Once placed, the truss can be aligned with structural grids or reference planes to define the roof pitch. The family is designed to be hosted within a structural project where individual members can have material parameters assigned to define the timber species or finish. Adjustments to the span and pitch can be made by modifying the instance parameters provided within the family properties to suit specific project roof geometry requirements.
