You then select the roof and choose the extension ribbon, in the modelling pull down you will see the two new modules, Rafter Framing and Roof Trusses. I will outline a brief workflow and then talk about some of the limitations and good things that I noted whilst testing the extensions.Īs I previously stated, you will first need to model a roof using either the Roof by footprint or roof by extrusion.

If the original roof geometry changes then you select one of the timbers and select modify on the Extensions ribbon, this will force the roof to rebuild.

The extension will create the 3D timbers and trusses for a number of different roof configurations from simple dialog boxes with intelligent previews. Both of the tools require the creation of a Revit roof object and the framing and trusses are hosted on this object.

The tools, once installed, will appear on the extensions ribbon and have two modules, one for rafter framing and another for roof trusses. Autodesk have recently launched a new roof timber framing extension for subscription customers following on from a similar tool for framing wall panels.
