Enhanced Framing Modeling and Documentation
Revit Structure 2011 offers enhanced design features including slanted columns, beam systems, trusses, and connection symbols. You’ll have more control and easier placement for slanted columns, more flexibility when placing and modifying beam systems and trusses, and the ability to display several new symbolic connection types for documentation.

More Accurate Representations of Reinforcements and Concrete
Reinforcement enhancements include 3D shape spiral rebar, slab edge reinforcement, configuring rebar sets, additional hook bend radius, and major spacing of area reinforcement in tags. Revit Structure 2011 includes enhancements to the joining and cleanup behaviors of complex concrete objects to help reflect a more accurate representation of model object geometry.

More Accurate Analytical Models
Revit Structure 2011 software enables greater visibility into your analytical model and provides a number of options for vertical and horizontal projection. Automated and manual adjustments of your columns, beams, and walls can now be made more accurately with greater flexibility.
