Autodesk have recently announced that the Revit Structure 2011 Extensions are now available for download for subscription customers. The mid release extensions normally generate a fair amount of anticipation on what is to be included. Below is a full list of the new features. Within the UK, the most prolific new feature is going to be the SDNF import and export.
Floor vibration analysis—Assess vibration characteristics to help meet requirements of the AISC Design Guide 11 (United States).
Gravity column analysis—Design steel columns based on the AISC 360-05 design code (United States).
SDNF import/export—Import or export SDNF file format.
SS3 link—Link data bi directionally between Revit Structure and SS3 so that engineers can use structural data from SS3 to create coordinated drawings and collaborate with Autodesk® Revit® Architecture software users (Japan).
Member section schedule—automatically generate member section schedules (Japan).
CSV element generator—Link to other structural analysis applications to automatically generate the structural model, including the rebar model, in Revit Structure using the CSV file format (Japan).
