From the Autodesk website:

AutoCAD Structural Detailing software is a powerful solution for detailing and creation of fabrication shop drawings for steel and reinforced concrete structures. Use specific modules for fast and efficient generation of steel connections and shop drawings, dynamic concrete models and formwork drawings, and automatic concrete reinforcement definition and concrete shop drawing generation.

We have placed this forum under the Revit Structure forums because this software is only available as part of the AutoCAD Revit Structure Suite which includes AutoCAD, Revit Structure and AutoCAD Structural Detailing as well as extensions that have been created by third parties for Revit Structure (available through subscription). It is our understanding that AutoCAD Structural Detailing is a rebranding of tools that were acquired when Autodesk purchased the French firm Robobat.

At this time this software only supports metric units.

Please use this forum to post questions regarding this software. As it develops we will consider revisiting the forum organization. Please feel free to offer your comments on this as well.

Thanks and enjoy!
