Learn about software improvements for structural engineering and analysis.
- Steel profiles: The Structural Section category for structural columns and framing elements provides new dimension parameters for columns and framing elements.
- Elevation parameters: To improve annotation and scheduling, the following fields are available:
- Elevation at Top (beams, braces, structural floors, and foundation slabs)
- Elevation at Top Core (multi-layered structural floors, and foundation slabs)
- Elevation at Bottom Core (multi-layered structural floors, and foundation slabs)
- Elevation at Bottom (beams, braces, structural floors, and foundation slabs)
- Reference Level Elevation (beams and braces)
- Release and member forces: To facilitate documentation and connections design and detailing, you can specify member end forces for columns, beams, and braces. This data can be scheduled and added to annotation labels. See Define Releases and Member Forces.
- Truss chord rotation: When rotating a truss, you can specify whether truss chords rotate with the truss or stay aligned with the truss placement plane. See Truss Instance Properties.
- Local coordinate system: The following Local Coordinate System (LCS) enhancements are available when working with analytical loads
- The LCS widget now displays on curved beams and arc walls. See Display the Local Coordinate System of an Analytical Element.
- When you place hosted loads oriented to the host LCS, the LCS widget displays on the element to show the load direction.
- Loads display properly for curved linear analytical elements oriented to the LCS.
- Area loads: The following enhancements are available when you place area loads.
- You can place hosted area loads on the surface of an arc wall.
- You can apply projected surface loads. Select the Projected Loads parameter to apply correctly scaled loads to a projection angle value. See Area Load Instance Properties.
- Rebar display performance: To improve performance so that views open and update faster, Revit regenerates reinforcement only for what is visible on the screen. In addition, if reinforcement appears very small on the screen, it is displayed as simplified lines, regardless of the detail level assigned to the view.
- Rebar placement: The following enhancements are available when placing rebar.
- Rebar Offsets: In the Rebar Constraint dialog, you can now specify rebar constraints to the host and an offset distance from the cover. See Apply Overrides to the Host Constraint Behavior of Rebar.
- Rebar Constraints dialog: You can now zoom, pan, and adjust your view without closing the dialog.
- Rebar rounding: When specifying reinforcement rounding defaults, you can round to the nearest increment, the next higher increment, or the next lower increment. See Reinforcement Rounding.
- Lock rebar parallel to host face: You can now place rebar parallel to any host face with precision using the Shift key during placement. See Place Rebar.
- Rebar shapes in paths: To improve reinforcement detailing of concrete, you can assign rebar shapes to the primary and alternating bars in a path reinforcement system. See Apply Alternating Bars in Path Reinforcement Systems.
- Rebar scheduling: To improve rebar documentation, you can now include the following parameters and fields in schedules and tags:
- Host Mark displays the name of the structural element hosting the rebar.
- Host Count displays the number of identical structural elements hosting the rebar.
- Quantity by Element displays the calculated value of the total number of rebar per host.
- Structural Analysis Toolkit for Autodesk® Revit®: The following enhancements are available:
- Gravity analysis: Apart from static analysis, you can perform gravity analysis. It is the analysis type which by deducing the flow paths of loads lets you determine how vertical loads are transmitted from the top to the foundation of the model. See Assumptions of the Gravity Analysis.
- Result Explorer: You can display and explore types of results for gravity analysis. See Available Types of Results for Gravity Analysis.
- Perform analysis: You can perform a batch of analyses simultaneously. In the Analyze in Cloud dialog, you can specify a type and parameters for several analyses. See Performing the Analysis.
- Website - 3D Structure Viewer: You can display results for static analysis and gravity analysis in 3D Structure Viewer. Moreover, you can display detailed results. Results for members and surfaces are presented in the Local Coordinate System (LCS). See 3D Structure Viewer.
- Website - 3D Structure Viewer: On mobile devices, you can zoom in/out, pan, and rotate a model using gestures.
- Website - project page: You can share an analysis with collaborators. Collaborators cannot edit results and cannot download them to the Revit project. They can view analysis results, view a report, and download the Robot model with and without results. See Sharing Analysis Results with Collaborators.
- Website - dashboard: You can open the Autodesk® 360 Structural Analysis dashboard on the website clicking Analyze tab > Structural Analysis > Open Dashboard.
- List of messages: You can toggle on and off the list of messages containing information about performed analyses by clicking Analyze tab > Structural Analysis > Messages.
- Revit - Robot Integration: When updating a Revit model with changes in section sizes, the link checks compatibility between the section size from Robot and family types loaded to the Revit project. If it identifies a family type compatible with a Robot section, it updates the Revit model with it. See Updating a Revit model.
- Revit - Robot Integration: You can specify which levels to transfer as story levels and which levels as structure axes to the Robot model. See General information.
- Revit - Robot Integration: During the Revit - Robot link process, orientation of loads is transferred. Loads are presented in the Local Coordinate System or Global Coordinate System, depending on how they are defined in Revit.
