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 attach to the analytical model of the rafters (we align the modeling plane to eh analytical model to the top chord of the truss). In a later vlog, we investigate how to split the purlins, so each segment attaches to the rafters.
