Revit 2021 – Purlins Array Split to Attach Nodes to Trusses



To a Structural Engineer, the AEC collection is of particular interest. Revit is used to set up both the graphical representation of the building, but also the “matchstick model” which is used to perform the structural analysis in Autodesk Robot. Robot is also used to model more complex shapes (to be analyzed) like parking garage ramps and to do code checking. Then there is Advanced Steel, which is essentially AutoCAD on steroids for steel fabrication.

It is not always clear to new structural users of Revit how to use the software for analytical modeling. In this vlog, we look at how to model purlins on rafters, so they can be managed in a group, By editing one of the group members, we can split the purlins where they intersect the rafters, causing them to attach to the analytical model.
