This download contains all previously released Revit Extensions and updates. In addition, this download includes enhancements to several extensions (such as Wood Wall Framing, Reinforcement Extensions, Load Takedown, and Composite Design) and two new features: Frame Generator and Shared Parameters Converter. Autodesk® Revit® Structure building information modeling (BIM) software for structural engineering provides purpose-built tools for structural design and analysis. With the advantage of BIM, Revit Structure helps to improve multi-discipline coordination of structural design documentation, minimize errors, and enhance collaboration between structural engineering and architecture teams.
