The structural analytical model was improved in several different areas.
Use Analytical Model Categories visibility settings to display Local Coordinate System (LCS) widgets along structural analytical elements in a view. The LCS for Columns is now consistent with the LCS for beams and braces. Hosted Loads and Boundary Conditions now can be oriented to the Host LCS. They also respect host LCS direction and rotate as the LCS is changed.
Revit and Revit Structure support the BIM process for structural engineers.
Revit provides a physical model to use for documentation and an associated analytical model to use for structural analysis and design.
An analytical model is a simplified 3D representation of the full engineering description of a structural physical model. The analytical model consists of those structural components, geometry, material properties, and loads, that together form an engineering system. The analytical model is created automatically while you create the physical model, and can be exported to analysis and design applications.
Perform energy analysis using detailed Revit models.
Automatically create an Energy Analytical Model directly from your Revit building elements and send it to Green Building Studio* for simulation using DOE2.2. Once the analysis is complete, you can review and compare results as you continue to iterate the model and help inform your design decisions.

Now an IFC file can be linked into an existing Revit project.
use the new Link IFC tool to link an IFC file to the current project. If you later change the IFC file and reload the project, the project updates to reflect the changes. Linked geometry has much better fidelity and associated parameters come into the Revit environment with the correct values and units.
Revit Server helps project teams in different locations to more easily collaborate on shared Revit models across a wide-area network (WAN).
Maintain an integrated collection of central Revit models on a single server that can be accessed from local servers. Built-in redundancy helps provide protection in case of WAN connectivity loss.
Revit 2015 has been certified by BuildingSMART International for IFC version 2x3 Coordination View import and export.
The components of Revit 2015 software—Revit Architecture 2015, Revit Structure 2015, and Revit MEP 2015—have been certified by BuildingSMART International for Industry Foundation Class (IFC) version 2x3 Coordination View 2.0 export.
The structural analytical model in Revit software can be bi-directionally linked with Robot Structural Analysis Professional software.
With bidirectional linking, your analysis results will automatically update your model. Parametric change technology coordinates those updates throughout your model views and construction drawings. Revit also links to third-party structural analysis and design programs, facilitating the exchange of structural analytical information. The types of information that can be shared include:
Use interference checking to scan your Revit model for collisions between elements.
Pinned elements are prevented from being deleted unless you specify. Elements must be unpinned before they can be deleted.
Delete elements by unpinning them and deleting, or deleting through the expanded warning dialog. Revit will now warn you that the element is pinned and instruct you to unpin the element before using Delete. Delete objects in a non-graphical context, such as deleted from Schedule.
Trim / Extend has been updated to enable for box selection of multiple elements.
When drawing a selection box from right to left, the elements do not have to be contained in the box to be selected. When drawing from left to right, only elements fully contained in the box are selected. This will improve your productivity by minimizing the steps it takes.
Easily adjust the Family Parameter order to company standards.
By default, new family parameters are now added in ascending alphabetic order to the parameter list, within the group that you selected when creating the parameter. Use the Sorting Order buttons (Ascending and Descending) to sort the parameters alphabetically for the current family. To further modify the order, select a parameter and use the Move Up and Move Down buttons to change the order of the parameters within a group. This parameter order is maintained in the Properties palette (instance parameters) and Type Properties dialog (type parameters) for the family when it is loaded into a project.
New Manage Assembly Code Setting dialog allows user to change UniformatClassifications.txt location.
The new Manage dialog allows you to modified the UniformatClassifications.txt location. There is a new warning indicator if there is an issue reading the Assembly Code file with an unsuccessful reload notification. The last loaded version of the Assembly code file is loaded into the document when open even if not found.
New capabilities and features enable precise definition and placement of structural framing elements in space.
Align the end of a joined beam to another beam, structural column, or structural wall. Reset beam ends that have been previously aligned.
Shape handles are now available to click and drag the end extensions or cutback of beams and braces in the drawing area. Use shape handles to directly manipulate framing element geometry and snap ends to other geometry or reference lines.
Quickly offset the physical geometry of framing elements using the Offset y and Offset z justification tools. Fine adjustments are now possible working directly in the drawing area without manually calculating and entering parameter values in the Properties palette.
Display the location lines of beams and braces in any view as a reference while modeling.
Structural Framing elements can be identified by their section type, containing consistent and unambiguous definition of sectional properties.
You can assign parameters representing expected characteristics to structural framing and structural column families. This can present unreliable information to external analysis and code checking applications. Improve data integrity within BIM workflows and get consistent parameters by applying a section shape category to structural framing families.
Document multiple rebar within a host, only showing a representative subset, allowing the creation of legible reinforcement documentation.
It gives you the ability to create better correct detail shop drawings of reinforcement. The bar presentation allows the reinforcement of structural elements to be displayed in a simple, more readable way. Defining different bar presentation for a rebar set in each separate view gives more flexibility in creating reinforcement drawings.
Parametric components, also known as families, are the basis for all building components designed in Revit.
They offer an open, graphical system for design and form-making as well as an opportunity to express design intent at increasingly detailed levels. Use parametric components for the most elaborate assemblies, such as cabinetry and equipment, as well as for the most elementary building parts, such as walls and columns. No programming language or coding is required.
In Revit, all model information is stored in one place. Any information that gets changed is effectively changed throughout the Revit model.
Revit software for structural engineering includes building materials such as steel, cast-in-place concrete, pre-cast concrete, masonry, and wood.
Since the buildings you design are constructed of multiple building materials, Revit building software enables you to model your structure using the materials you need.
More quickly and easily define and visualize concrete reinforcement.
Methods for managing the definition of reinforcement as well as controlling its placement include:
Minimize the need for saving and maintaining working views. This feature allows you to change view properties without affecting the saved view state.
Parameter to control the visibility of Hidden Lines in your views.
Structural and MEP users now are able to turn off their hidden lines for an entire view. Show or hide the hidden lines of your geometry independent of what discipline your view is set to.
In view properties, use the new Show Hidden Lines parameter to control the display of hidden lines in the current view. You can also define this parameter for view templates. Easily see the hidden lines of openings in Walls and Floors. Display all hidden lines automatically in 3D views for better documentation.
You can now delete revisions and better sketch revision clouds shapes.
Deleting a revision removes the revision and all of the revision's associated clouds and tags from the model. You can use standard draw tools, such as a line or rectangle, to sketch the revision cloud shape. Pressing the Spacebar, you can flip the arc direction in the cloud shape. You can also specify the minimum arc length for revisions clouds in a project on the Sheet Issues/Revisions dialog.
When you move a tagged element, or drag the tag head, the tag leader and elbow adjustment behavior is now consistent with that of text leaders.
When you move or adjust the tag, the portion of the leader from the element to the elbow is flexible, while the portion from the elbow to the tag remains fixed.
The instance property Elevation at Top has been added to isolated foundations, wall foundations, and foundation slabs. Elevation at Top specifies the elevation of the highest point or plane of the foundation. Use this information in tags when documenting a project.
Schedule Enhancements with Parameters, Filter & Grand Totals
Base and top constraint wall parameters are now available for schedule (Base Constraint, Base Offset, Top Constraint, Top Offset & Unconnected Height)
Grand Totals can now be customized using the ‘Custom Grand Total Title’ field and the Schedule Properties ‘Filter’ options have been expanded from 4 to 8 rows.
Include images in schedules to convey graphical information for elements.
Image Instance and Type properties have been added to many elements to allow you to associate an image with an element instance or type. These images can then be included in schedules and will display when the schedule is placed on a sheet.
Keynoting revision dialog has a single path with absolute / relative / library locations.
Simplification of dialog to a single path with absolute, relative or library locations. There is a new warning indicator if there is an issue reading the keynote file with an unsuccessful reload notification. The last loaded version of the Keynote file is loaded into the document to add keynote tags when open even if not found.
When you duplicate a view "Copy 1" is now added to the name.
Rebar and fabric reinforcement now have number sequencing that matches with existing reinforcement.
Numbering allows identical reinforcement elements to be matched for schedules and tags. In assigned partitions, the rebar and fabric sheet numbers match those of the same type, size, material, and shape. The number for a rebar or fabric sheet instance may be viewed in the Properties palette under Identity Data.
Modeling tools help you derive better construction insight from design models.
Split and manipulate objects, such as wall layers and concrete pours, to more accurately represent construction methods. Prepare shop drawings for fabrication with features that give you greater flexibility in documenting assemblies of model elements.
Create details from views of a 3D model with additional annotations or from scratch with Revit for structural engineering 2D drafting tools.
Import details from conventional CAD files. To help save time, import entire sheets of typical details in DWG™ format from previous projects. Dedicated drafting tools are available for structural modeling of steel and reinforced concrete details, such as:
Achieve a hand drawn, informal sketch look, by just pushing a button.
Presentation Sketchy Lines graphics gives you two parameters for adjusting the look of the sketchy lines, Jitter and Extension. The tool is available in all views and you can work while Sketchy Lines are turned on.
