Fit and Finish
By further building upon the enhancements made in prior releases, Revit Structure 2011 promotes continuity across releases in an effort to make features and functionality more complete and help boost customer satisfaction.
Slanted Columns
In Autodesk® Revit® Structure 2010 software, engineers and drafters could create slanted columns using the same column families they have used for vertical columns, which include not only physical characteristics, but also analytical as well. Users could place the slanted column in elevation, section and 3D views and had some control of the slanted column end position and behavior.
Autodesk® Revit® Structure 2011 software provides the following slanted column enhancements where one can now place slanted columns in a plan view in the same workflow as the 2-click method of placement in 3D views. Users can adjust the slanted column along an attached beam and be able to cut the slanted column to an attached structural floor or slab. Additionally, users can cut a slanted column horizontally, vertically, or perpendicularly, even when it is not attached to an element. Beam joins will now automatically adjust when resizing an existing slanted column
Beams Systems
Today, many engineers and drafters model each structural member that comprises the flooring system. Although the beam system tool in previous releases allowed users to efficiently layout a set of beams, Autodesk has now enhanced this tool to allow better accuracy and placement of the beam system elements.
In Autodesk Revit Structure 2011, beam systems now allow users to select a support such as a wall or beam to specify the direction of a beam system. Users can also draw a sketch line inside or outside a beam system to specify beam direction and can also drop the beam system using the Remove Beam System tool. Once dropped, the individual beams will remain in place.
Trusses
The creation of truss elements is frequently a time consuming task for engineers and drafters. The previous release of Autodesk Revit Structure allows users to add trusses to their building model more quickly according to the layout and other parameters specified.
In previous releases, users were able to attach the top chord to roof or slab elements, edit the location of the top and bottom chords, and were able to unlock the truss elements from the truss family.
Now, Autodesk Revit Structure 2011 has enhanced these features starting with the ability to attach the bottom chord of a truss to a structural floor or foundation slab element. Users can also simultaneously sketch custom chords while the truss is attached and be able to remove a truss family. Once dropped, the truss chords and webs will remain in place.
Concrete Reinforcement
Many engineers and drafters detail concrete models with individual rebar, rebar sets, area and path reinforcement. Autodesk® Revit® Structure 2011 now provides the following structural reinforcement enhancements to help aid in the rebar replacement to your concrete elements.
First, reinforcement volume and length project units can be specified with appropriate numerical rounding and representation. Second, concrete slab edges are now valid hosts for cover and reinforcement. The first and last bars in rebar sets are now suppressible in a project. Third, an additional rebar bending radius has been implemented to meet the needs of some international codes. Cover reference line style can now be configured in the Object Styles dialog and the cover reference lines now remain in view when resizing and repositioning rebar. Fourth, major Spacing is now a label category parameter for area reinforcement tags. Finally, you can now specify and place spiral rebar in a concrete host. Because spiral rebar is fully dimensional it requires a unique shape family and can be scaled, rotated, and resized accordingly.
Analytical Model
Revit's Analytical Model allows the user a number of options in vertical and horizontal projection with multiple options for adjustment. Autodesk® Revit® Structure 2011 now has improved tools where one can horizontally project from columns to the default plane, the auto‐detected plane, or a named reference plane.
Users can also horizontally project from the center line of a beam, location lines, grids, and named reference planes as well as set the horizontal projection from the center of a wall core to accommodate varying widths in structural walls. Top or bottom vertical projection of a column will now auto‐detect to beams when structural floors are not present and vertical projection from beams from the locations line or bottom of a beam.
Also, for columns, one can use the top or bottom of a column analytical model as a source for manual analytical adjustment. Finally, just like users can add rigid links to columns, users can now set rigid link parameters for beams. This rigid link of beams will adjust to the columns they are attached to and will take into consideration all other columns within the same space of the beam. This allows for rigid links along a beam between its connected ends.
Connection Symbols
In construction drawings, connection types can be shown using various symbolic annotations at the end of the structural elements. Autodesk® Revit® Structure 2011 now provides several new connection symbol families that can be loaded and selected as default connection symbols through a new interface in the Structural Settings dialog.
