Autodesk Revit is a software for BIM (Building Information Modeling). This is your source for information on the direction of software development, insider tips and tricks, and industry trends that can help you get most from the software and work better with cloud-connected BIM.
Generally portal frames are used for single-story buildings, but they can also be used for low-rise buildings with several floors where they can be economical if the floors do not span across the building.
Let me walk you through details on these nodes and how to put together a sample script using them.
The first two nodes I would like to talk about create a 2D frame geometry (Fame.ByWidthHeights, Frame.ByWidthHeightAngles). They do the same thing and they differ by input parameters only.
angle – Beam angle. The angle has to be greater than or equal 0 and less or equal than 60 degrees.
The Frame.Copy node helps you duplicate your 2D input frame geometry with a specified spacing between frames. The spacing can be equal of varying.
frame2DGeometry – 2D Frame geometry. Input value should have the following data structure: Curve[Column, Beam] withEqualSpacing – Spacing type. True = equal spacing, False = varying spacing. numberOfTimes – Number of times a 2D frame should be copied when spacing between frames is equal. spacing – Spacing value between frame when distance between them is equal. varyingSpacing – Varying spacing. Default value: [6, 5, 4, 5, 6] flip – Toggles the frame orientation.
The Frame.Purlins node creates purlins elements between rafters.
rafters – Rafters. number – Number of purlins. dp1 – Start offset. dp2 – End offset.
The SideRailsEavesBeams node creates side rails and eaves beams between columns.
columns – Frame columns. heights – Z coordinates of beam ends.
The last two nodes I would like to talk about create X and V bracings.
points – Element end points.
zones – Frame zones. A zone is a space between 2D frames, e.g. between frame #1 and frame #2 we have zone #1, between frame #2 and frame #3 we have zone #2 etc…
Building a sample script using the nodes I covered is easy. Simply connect these nodes in this way…
…to get the following output:

Great news for PlanGrid users: PlanGrid–an Autodesk company– has released PlanGrid BIM, a powerful new product integration with Revit that lets you access BIM data from Revit directly within PlanGrid on your mobile devices. With this integration, PlanGrid users can now drill down into rich data in an easy-to-use 2D interface or 3D environment. This can empower teams to build with greater accuracy, avoid rework, and make decisions in the field faster and with more confidence.
PlanGrid’s new BIM functionality includes:
Revit Integration: Sheets are published directly from Revit into PlanGrid, promoting accuracy of BIM data, as well as sheet titles and numbers; drawings continue to include PlanGrid features such as automatic callout detection and hyperlinking.
BIM-enabled Sheets: Tap objects to access BIM data properties, such as an object’s dimensions, material type or manufacturer, all within the familiar 2D environment.
3D BIM Viewer: Load a 3D environment instantly with a simple tap, allowing you to seamlessly transition into a 3D view of a specific object, even if offline. Features such as zoom and snap tools for taking measurements between model objects are included. Note that the 3D BIM viewer is currently in open beta.
PlanGrid BIM is available to all PlanGrid users for use on iOS and web, with functionality in Android and Windows to follow. PlanGrid will soon further its aim to help increase construction productivity by supporting integration with other design and project review software such as Autodesk NavisworksⓇ, two-way synch to update the master BIM model with data from the field, and the ability to generate tasks, RFIs and punchlists from model data.

If you thought the December 2018 update to Revit cloud rendering was a big deal, you were right. But those updates were only some of what the team was working on. That initial release has been followed by several big incremental improvements that are no less than spectacular.
I’m really excited to share these additional updates to Revit cloud rendering that will make your renders on average 30% faster.
Single-frame splitting speeds up rendering significantly by breaking a large single image into smaller pieces and rendering each piece separately on a different machine. This allows big images to be optimized across many different rendering machines at the same time. Post-render, the image is reassembled. Depending on size of image and render quality setting, you’ll see render times two to ten times faster than what you had before.
Autodesk Rendering for Revit - YouTube
Filter-based quality metrics is a new feature that can speed up rendering time by an average of 30%. Specify the desired quality level, and Revit cloud rendering monitors the quality of an in-progress rendering and stops the render when the specified desired quality has been reached. With filter-based quality metrics, you can avoid costly and useless cycles that don’t contribute to image quality. Depending on the image and subject being rendered, the impact on total render will vary from cutting render time in half to smaller improvements.
Here’s the bonus: taking advantage of those significant average render time savings, we also bumped up some quality settings to allow increased refinements of hard-to-render image details.
We are excited to deliver functionality in Revit 2020 —responding to several related requests on the Revit Idea Station– for better support of the creation and documentation of electrical distribution systems containing panels with feed through lugs. For those of you using external tools to do more in-depth analysis, this enhancement provides a more accurate model for analysis and circuit coordination by eliminating a breaker in the model and using feed through lugs instead.
A new panel schedule template, called Feed Through Lugs Panel, is included in the US Imperial and Metric Systems-default and Electrical-default templates.
This template demonstrates usage of some additional parameters that summarize loads that are directly connected to circuits in the panel (This Section Total), parameters that summarize loads that are fed from a child panel through feed through lugs (Total Load Connected To Feed Through Lugs), and a set of parameters showing the overall totals (Panel Grand Totals).
For a panel to feed another panel through feed through lugs, you first need to enable the feed through lugs on the panel. This is an instance parameter that you can set as the default in the family editor.
With Feed Through Lugs enabled, create a circuit to connect one panel to another and select whether the circuit is fed from a Breaker or from Feed Through Lugs.
Once the connection is made, use the Circuit Numbering Option setting to continue the circuit numbering from one panel to the next. For example, if the first panel is numbered from 1-42, select Continue Numbering on the second panel to start the number with 43 as shown below.
Note that we did not make any changes to how Sub Feed Lugs behave. During our research, we heard from users that Feed Through Lugs is more commonly used than Sub Feed lugs, so we made those improvements first. We moved the Sub Feed Lugs property from type to instance.
If you have specific needs for how Sub Feed Lugs should work, please post the details on the Revit Ideas page.
We’re excited to announce the latest release of Autodesk’s structural steel detailing software, Advance Steel 2020.
Here is an overview of some of the new and enhanced features available in this version.
1 – Propagation of steel connections
In Advance Steel 2020, you can automate steel connection creation by propagating connections already in place. Just select the joint box from one connection and select the Propagate Joint option available in the contextual menu. The steel connection will then be automatically inserted in other locations where the framing conditions are similar. Since all these connections are now part of the same group of connections, modifying this connection will automatically update similar connections accordingly.
Advance Steel 2020: Propagation of Steel Connections - YouTube
2 – Align labels on drawings
Once you have created a view on the drawing, you can rearrange the labels to improve the look of your drawing. With Advance Steel 2020, you can move a label to a different location and apply this modification to other labels by using the new option Arrange labels, you can also align labels to a reference object or to an AutoCAD line. In this case, choose the Align Labels to Reference option in the contextual menu.
Advance Steel 2020: Align Labels on Drawings - YouTube
3 – More control on hole labels on drawings
When moving a hole label, the arrow of the label leader line automatically jumps to the closest labelled hole, creating a shorter leader line and making the drawing more readable. You can disable this new behavior by unselecting a new option available in the properties dialog box. In addition, the arrow of the label leader line now remains outside the hole which brings more clarity to the drawing.
Advance Steel 2020: Hole Label Behavior - YouTube
4 – Cut view symbols alignment on drawings
In Advance Steel 2020, you can automatically align cut view symbols to improve the look of your drawings. The Align Cut View Symbols to a reference symbol command (available in the ribbon) aligns all the cut symbols from one side by using a reference symbol. This simplifies the cut symbol arrangement and ensures that the cut symbols will not move during a drawing update.
Advance Steel 2020 offers additional possibilities for customizing cut view symbols. The cut symbol template (defined in a DWG file) has several new features to help with customization, including new tokens, support for user text, text formatting using the template text style, and text color control from the template file. In addition, new defaults available in the Management Tools help you define which cut view symbol DWG file you want to use for upper and lower cut symbols.
6 – Cut view title customization
You can now customize the cut view title with two new tokens. The Scale Token shows the current cut view scale, while the View Number (A) shows the cut view number using a single letter. You can configure the two tokens using the cut view configuration page in the Drawing Style Manager, or when editing the cut view title properties on existing sheets.
7 – High DPI display support
Advance Steel 2020 now supports high-resolution monitors. Enhancements have been made to the user interface, including ribbon icons which correctly size high DPI scaling and text and buttons which automatically scale in dialog boxes to improve the display.
8 – Dialog boxes display enhancement
Advance Steel 2020 comes with dynamically adjustable sidebars size, with the sidebar width automatically adjusted based on the longest text to display. This is valid for all dialog boxes with a sidebar, which gives a better user experience when reading long texts in the side bar.
Advance Steel 2020: Enhanced Dialog Boxes With Sidebar - YouTube
9 – Installation in Czech language
Advance Steel 2020 can be installed in different languages, including in Czech. Once installed, you have access to ready-to-use dedicated localized templates such as drawing styles, drawing processes, and bill-of-material templates. This enables Czech end-users to use Advance Steel in their native language.
10 – Local content for US English
With the installation of Advance Steel 2020 in US English, users receive access to a more localized version for the US market. This includes files like a new cut symbol added for general arrangement drawings or new process suites to speed up shop drawings creation.
Autodesk Revit 2020 delivers several new functionalities. One that stands out from the rest was created for the structural engineer. Steel Connections for Dynamo and its sample scripts will help engineers to work more productively when modelling, placing steel connections, optimizing design and material consumption.
Dynamo for Revit users can create rules for adding steel connections on a structure or a selected part of it, based on new Dynamo nodes that are grouped under a new package called Autodesk Steel Connection 2020. These nodes can identify similar geometrical conditions for placing standard and custom connections and enable a simple flow of rules. Starting from previously selected model elements, these are grouped into potential connection nodes. They are filtered on certain criteria (which can be related to section, slope angle, slant angle, angle between the axes of the elements, and zone type). Finally, the connections are placed.
But before all of this starts to sound too technical, it’s important to point out that the rules can be controlled from Revit by using the Dynamo player where the main parameters can be tweaked so that connections are placed as needed. The collection of out-of-the box scripts that are delivered with the Dynamo package represent both tools for immediate use of placing various connections types in steel buildings and building blocks for bespoke workflows, depending on the requirements of each project.
Revit 2020: Steel Connections for Dynamo - YouTube
Democratizing automated processes played a key role in defining our mission and that is why we believe rules need to be controllable by any structural engineer from within the environment that you are most familiar with. And this is what we encourage Dynamo experts to pursue when implementing customized standardization of rules for placing connections by an open rules-based system in their own companies.
Imagine all the benefits of this new tool: increased productivity, greater optimization, and improved quality of modelling by reducing the number of manual operations needed for creating steel connections. In addition, you’ll benefit from improved coordination with architecture and MEP by having a detailed model available for clash checks in the early phases of the project.
Before concluding, it is important to make a reference to another feature aimed at enhancing the modelling productivity for steel connections – Standard steel connections propagation. This delivers an easy and fast way to place a standard connection by propagating it automatically everywhere in the model where an identical context is found. To have more control and a wider range of applicability, the Steel Connections for Dynamo can be used to place standard and custom connections in the selected part of a model based on rules that are configurable and allow for various filtering criteria.
As always, please voice your feedback as we pursue the vision of automating connections design. Let us know your ideas for making it easier, faster, and better for all users.
Thank you for patiently waiting for the launch of Robot Structural Analysis 2020! We’re happy to present numerous improvements and code updates that will make you more productive using BIM-based analysis and design. For the complete list of features, please refer to the product documentation.
I want to express our gratitude to everyone who also participated in the feature suggestion session last December. Please note that we’ve looked at all of your suggestions and prioritized accordingly. We cannot implement all of them at once, so you will see more in the future. Here is the public roadmap for Robot Structural Analysis.
Please give the new Robot Structural Analysis release a try, and let us know what you think..
Ruslana Steininger, Product Manager for Structural Analysis
Autodesk is committed to investing in Robot Structural Analysis to improve your experience with this software and help you maximize the value from your investment in the Architecture, Engineering & Construction Collection.
I am pleased to share that we have just released Robot Structural Analysis 2020. The 2020 version contains several new features and improvements for structural analysis and code-checking design.
Here is a quick overview of what you can find in Robot Structural Analysis 2020.
A load combination results when more than one load type acts on the structure. Building codes usually specify a variety of load combinations together with load factors (weightings) for each load type to ensure the safety of the structure under different maximum expected loading scenarios.
Now you can more accurately generate load combinations. The following new code combination regulations have been added into Robot Structural Analysis Professional 2020:
American Codes: LRFD ASCE 7-16 and ASD ASCE 7-16
Canadian Code: NBCC 2015.
Enhanced Seismic Analysis
In addition to the seismic load analysis using the Response Spectrum approach, Robot Structural Analysis also contains the Equivalent Lateral Force method. The Equivalent Lateral Force method is an alternative (simplified) approach for determining distribution of seismic base shear force on the height of regular, multistory buildings. Robot Structural Analysis 2020 contains a new instance of the American standard ASCE 7-16. You can set up a seismic analysis according to ASCE 7-16 for both methods: the Response Spectrum and the Equivalent Lateral Force method.
In addition, a new parameter (Disregard density) in the simplified seismic method (Equivalent Lateral Force) is available. This parameter allows you to exclude the density of the structure element (ρ=0) during the dynamic analysis of the structure. Instead of using self-weight, you may add masses converted from loads. This allows for a control of the mass distribution on a mode.
This feature enables you to more accurately generate seismic loads by referring to the latest building code for the US engineers.
Enhanced Buckling Analysis
Buckling analysis is a technique used to determine buckling loads where a structure becomes unstable. Buckled mode shapes is the characteristic shape associated with a structure’s buckled response. In Robot Structural Analysis 2020, a new parameter is available in Buckling Analysis (Determine positive critical coefficients only).
This parameter allows you to exclude the non-physical buckling shapes during the buckling analysis of the structure. This new feature gives engineers greater control over the buckling analysis of the structure.
Enhanced Footfall Analysis
Footfall analysis examines the effect of human footfall loading (interpreted as a harmonic force in a certain frequency interval) on structure vibrations.
Footfall response is of interest to users concerned about the vibration induced in their structures due to walking related activities. As advances in structural design result in more efficient and lighter irregular structures, sensitivity to vibration of the structures is becoming increasingly significant. In Robot Structural Analysis 2020, footfall analysis according to SCI P354 is updated to Revised Edition of February 2009. This update gives you more reliable results of the effect of human footfall loading.
One of the most important results of this analysis is a response factor which specifies how many times the calculated vibrations exceed allowable vibrations. This type of analysis is required for hospitals, laboratories, or sports stadiums.
New Edition of the American Reinforced Concrete Design Code
Robot Structural Analysis has extensive support for the design of reinforcement in concrete members. This type of design is further divided into two parts: the design of required reinforcement which calculates the required steel section areas for concrete members, and the design of provided reinforcement which can be used to check and design the actual bar counts, types, and layouts for transverse and longitudinal reinforcement in concrete bar elements.
The new ACI 318-14 code is available in the following reinforcement concrete modules: beams, columns, slabs, walls and foundations (isolated and continuous footings). This national standard is also available in the required reinforcement concrete modules for bar and plate elements.
This feature extends the library of international design codes for concrete structures.
Update of Eurocode Design Codes for Reinforced Concrete
The following EN Eurocode National Annexes have been updated:
• EN 1992-1-1:2004/A1:2014 (Main code)
• PN-EN 1992-1-1:2008/A1:2015-03/Ap2:2016-10 (NA Poland)
• SFS EN 1992-1-1:2004/A1:2014 (NA Finland)
• NS-EN 1992-1-1:2004/A1:2014/NA:2008 (NA Norway)
• NF EN 1992-1-1:2004/A1:2014/NA:2007 (NA France)
• UNI EN 1992-1-1:2004/A1:2014 (NA Italy)
• NA to SS EN 1992-1-1:2008/A1:2014 (Singapore)
• NBN EN 1992-1-1/A1:2014 ANB:2010 (NA Belgium)
• SR EN 1992-1-1:2004/A1:2014 NB 2008/A91:2009 (NA Romania)
This update enables you to design concrete structures more accurately by extending international design codes for concrete structures.
New Editions of Steel Design Codes
To support structural steel design, Robot provides a Steel/Aluminum Design workspace with all necessary tools. Robot Structural Analysis 2020 provides current steel design codes to support American and Canadian markets. US and Canadian based engineers can quickly verify and optimize designs of their steel structures according to the latest building codes.
This feature extends the library of international design codes for steel structures.
These new features and improvements improve the accuracy of structural analysis and code-checking. To see a full list of changes, please read the help document.
The installation is available via Autodesk Desktop Application. We look forward to hearing your feedback.
