Autodesk Forge – the data platform of the future – BIM Blog

[ad_1]

Autodesk Forge is a cloud-based developer platform that offers direct access to model data in the cloud and can not only display it, but also supports cross-team and cross-process collaboration and offers a range of possibilities for process automation in various areas.

The Forge platform consists of several components, also called APIs (Application Programming Interface). The Forge Viewer is the fundamental end-user visible component that enables model viewing – this viewer is also used in the Autodesk Construction Cloud.
You can, however, with one Forge application create your own viewer and integrate it, for example, on your own website or the company’s intranet to display your models stored on the Autodesk Cloud. This has the advantage that you can adapt the viewer exactly to your needs, hide or show certain functions or integrate completely new functions – such as diagrams or mass evaluations.

Here are some interesting application examples and inspiration:

  • Example of our Forge team with some optional built-in extensions: Forge Extensions (autodesk.io)
    The extension is particularly interesting visual clusterswhich automatically sorts the model by category, which provides a very good overview of the built-in elements:
  • Tailored digital twin according to our own specifications for all areas: Autodesk Forge: Digital Twin Demo
    Annotation: Autodesk Tandem is the platform for the real estate sector and offers a ready-made solution for document transfer and digital twins. With Autodesk Forge, on the other hand, you can develop your own digital twin platform according to your own specifications.

Now how can you get started with Forge yourself?

As already mentioned, Autodesk Forge is a developer platform and therefore requires at least basic knowledge of HTML, CSS, as well as Javascript or .NET. The Autodesk Forge team offers a number of free Forge training opportunities for anyone interested:

Forge online boot camp are free, four-day events and usually take place twice a year. The first 3 days are dedicated to the viewer and you will learn how to upload models, retrieve your models from the Autodesk Cloud and extend the viewer with dashboards:

You can always access the recordings of the last boot camp on the official YouTube channel: DevTV from Autodesk – YouTube

That Forge accelerator program is available to you in the next step if you already have a clear idea of ​​your desired application. As part of the accelerators, which are also free, you can work on your application online or on site (in this case you only have to pay the travel expenses) and get direct advice from the Autodesk Forge specialists.

Lightning Talks are webinars on special topics, such as the automated IFC export from Revit or the integration of point clouds in Forge, which are of course also available to you as recordings afterwards.

We wish you every success with Autodesk Forge!

Revit 2023: Automatisieren Sie Workflows mit Revit-Daten mit Microsoft Power Automate

[ad_1]

Revit 2023 ermöglicht Autodesk AEC Collection-Abonnenten eine neue Datenverwaltungs- und Automatisierungsfunktion.

Der Revit to Microsoft Power Automate-Workflow verbindet Revit-Daten mit dem Microsoft Ökosystem. In diesem Beitrag stellen wir den Workflow vor, stellen einige Anwendungsfälle und Vorteile für AEC-Projektteams dar und verweisen auf einige Ressourcen für den Einstieg in die Erstellung Ihrer eigenen benutzerdefinierten Automatisierungen.

Was ist Power Automate? 

Power Automate ist eine Low-Code-Prozessautomatisierungsplattform, die Workflows zwischen Apps und Diensten verbindet und rationalisiert. Sie können es verwenden, um Ihre täglichen Aufgaben zu automatisieren, wie z.B. Dateisynchronisierung, Sammeln und Freigeben von Daten oder Senden von E-Mail-Updates und Benachrichtigungen. Viele Branchen nutzen Power Automate, um Geschäftsprozesse zu verbinden und zu automatisieren – nun ist das auch in BIM Projekten möglich.

“Wir freuen uns, mit Autodesk zusammenzuarbeiten, um AEC-Projektteams bei der Verbindung von Projektdaten mit Geschäftsprozessen zu unterstützen. Dadurch können nicht nur alltägliche Aufgaben automatisiert, sondern auch Daten einfacher geteilt werden, wodurch mehr Zeit für kreative Aufgaben bleibt.“

– Per Mikkelsen, Principal Group Program Manager, Microsoft

Was werden Sie automatisieren?

Es gibt viele Möglichkeiten, wie Sie Power Automate verwenden können. Sie können beispielsweise einen Flow in Power Automate erstellen, um eine Excel-Tabelle zu aktualisieren, wenn eine Änderung an einem Türelement auf einer Ebene in Ihrem Revit-Modell erfolgt. Oder senden Sie eine automatisierte wöchentliche Berichterstattung über Outlook, Teams oder Slack, die bestimmte Änderungen zusammen fassen. Sie können Auslöser erstellen, um Power BI-Projektzustands- und Leistungs-Dashboards zu aktualisieren, so dass Sie Daten sicher mit Geschäftsbeteiligten teilen können.

Mit Hunderten von Apps und Tausenden von Entwicklern, ganz zu schweigen von einer geschätzten Milliarde Microsoft-Benutzern weltweit: Der Revit to Power Automate-Workflow ermöglicht es VDC-/ BIM-Managern und Projektteams, Datenflüsse, Trigger und Transaktionen zu erstellen, die die Arbeitsweise von Teams, Projekten und Unternehmen verbessern.

Was Sie brauchen, um einen Datenaustausch zu erstellen

Is the industry ready for IFC4?

[ad_1]

This page shows the status of IFC certification for a given software. As you can see, the list of IFC2x3 software is pretty long, all of them are certified in MVD called Coordination View 2.0. Though, with a pinch of salt I want to point out, that from the list of numerous IFC viewers/clash detecting software, I found only Solibri, DDS-CAD and usBIM to have IFC 2×3 Import certificates. I am especially concerned that the so-called Field BIM programs that are used on tablets on a construction site don’t have the certificate. In the case of constructing from the model with incorrect model representation, this can cause a serious risk of errors on site.

The side of the IFC4 certification process looks less satisfying. There is a list of software that is certified for export, but it’s much shorter than the list for IFC2x3. And it makes plodding progress. As an example, popular Revit obtained IFC4 Reference View certification no earlier than the end of 2020 (with the release of Revit 2021). Reference View and Design Transfer are new MVDs introduced by buildingSMART for IFC4 (more about them here).

So far, the number of software certified for Design Transfer export has been full and round 0. We definitely have to wait to be able to round-trip our models between software. Unfortunately, no certification process has even started. I am actually not sure whether buildingSMART has finished the test specification.

Certification for importing IFC4 looks even worse. Only two software have obtained the certificate (Tekla and BridgeBIM). All the other popular IFC viewers and checkers are still in the certification process. This means that after we open a model in the IFC viewer, we cannot be sure whether the software has processed the data correctly. As a matter of fact, even if a designer performs a correct export to IFC4, a BIM Coordinator can find issues (for example in graphic representation) that haven’t existed in the “pure” IFC4 file.

Revit 2023: Library based automation of steel connections

[ad_1]

While in the last post we gave an overview of the Innovations in the field of structural design we would now like to take a deeper look at the developments in automated connection creation. With the library-based automation of steel connections, we pursue four main goals, each of which represents a benefit for civil engineers.

  • Fewer iterations with fabricators for joint modeling
  • Faster modeling of the proposed design
  • Earlier estimation of constructability and cost for entire models with connections
  • New business opportunities to extend services to structural steel detailing

Fewer iterations with fabricators for joint modeling

Civil engineers and fabricators can create their own specific connection library rules, which then serve as the single source of information for all new projects.

In Revit 2023 you will find example libraries of steel connection types such as the typed connections according to DStV. Automatic mapping between the connections suggested in the tables and the steel sections they match, as well as the ranges of compatible end forces on members, speeds up modelling. Single or double angle connections, end plate connections, but also fin plates, column connections, base plates and many other typical connections like these are part of various Revit 2023 content packs available through your Autodesk Account Portal or Autodesk Knowledge Network.

You can further extend or customize these libraries by creating new connection types, duplicating or editing the existing ones. During this step, you should contact the fabricators and fabricators you are working with and ask them to agree on the rules they want to follow for the next few projects, such as: B. using connections with a certain bolt grade, avoiding any kind of chamfers or preferring fin plates with two bolt rows instead of one. The “Allocation of connections to profile sizes” is a universal tool for all engineers to formulate the rules they have to respect for each type of steel connection. Once these are stored in libraries, they can be reused across projects, saving countless hours and giving you peace of mind that manufacturing companies will be making fewer requests to you. You might even consider turning the connection libraries into contractual agreements.

In addition to the DStV connections “Typified connections in steel construction according to DIN EN 1993-1-8” – 2013, the tables are based on the AISC Steel Construction Manual 15th edition and 14th Edition, the BCSA and SCI publication P358 – “Joints in Steel Construction – Simple Joints to Eurocode 3” – 2014 Edition (also known as the “Green Book”). For more information, see the available libraries here.

Faster modeling of the proposed design

Imagine how easy it is to create the steelwork preliminary design with steel connections when you can take the connections you need off the shelf and place them in the model based on automation algorithms.

With the libraries defined, the next steps of connection automation make for a simple, cohesive workflow: start with your new Revit preliminary design model, transfer it to Autodesk Robot Structural Analysis Professional or any other analysis software that can exchange analysis results with Revit, to perform the structural analysis and bring it back to Revit where our out-of-the-box rules read the results, look into your favorite libraries and match the steel element nodes with compatible connection configurations and automatically model the steel connection types.

To make managing the rules easier, we’ve created separate rules for each of the typical types of connections that appear in our sample libraries. I strongly recommend you this page to get a detailed overview of how to use these rules efficiently.

This reduces the risk of accidentally placing endplates with 4 rows of bolts instead of 5, as our automation mechanism compares the actual shear force from the specified load combination to the capable force defined for each connection type and places the one that can withstand that force. You can also reduce the risk of other problematic scenarios with potentially large material waste, such as: B. Using connections designed for beams made of S275 on a model made of S355 elements, since the application areas can also compare the steel grades.

Earlier estimation of constructability and cost for entire models with connections

Since connections can now be placed much more quickly, this means that more detailed design models with connections can also be created faster. This enables engineers to calculate their bid faster and more accurately before submitting it for a tender, increasing their competitiveness. You have more time for further iterations of the design and can save yourself some of the tedious phase of modeling connections.

The constructability can also be checked earlier, because as soon as the connections are modeled, you can start with Autodesk BIM Collaborate easily perform a collision check. In this way, the preliminary design is much closer to the final detailed model compared to a traditional workflow.

New business opportunities to extend services to structural steel detailing

With a faster steelwork pre-design process with connections, and the ability to incorporate steel connection types and placement rules into the various individual requirements of fabricators and other project stakeholders, it might make sense for some structural designers to add value to their services by including in start the detailed planning. The Revit models would be richer in BIM data at a stage similar to that typically only achieved by detailers/steelwork designers. You transfer the model to Advance Steel, add the remaining manufacturing-specific logic and automatically create the workshop drawings and NC files.

Our product manager Dan Peticila sees it this way: “I am not saying this is a trivial shift. Contractual agreements and industry practices don’t change overnight, but they are not set in stone either. They evolve, just like us, based on the knowledge we all amass day by day. This is what the visionaries from the industry have taught us, and this is why we put our effort in delivering these new tools. So that structural engineers can work more efficiently and deliver more value.”

What’s new in Revit MEP 2023

[ad_1]

We are excited to deliver capabilities in Revit 2023 that cover all aspects of the electrical and mechanical design workflow. from early conceptual design and analysis to the creation and documentation of design results, along with enhancements to support detailed design for construction.

These improvements relate to a number of strategic areas, including the use of analysis as a design basis and the use of models as design work products. They also address quality of life issues from BIM practitioners, some of whom were among the top votes on the Revit Idea Station.

Let’s get into that.

NEW ANALYTICAL WORKFLOW FOR ELECTRICAL PRELIMINARY DESIGNS

We are excited to offer electrical engineers and designers a new early-stage design workflow. The concept is similar to that Systems Analysis Framework the HLS engineers since the release 2020.1 is made available. The new capabilities enable electrical engineers to define design information relevant to power distribution in Revit early in a project.

Unlike traditional workflows where engineers manage information in different places—spreadsheets, DWGs, and often PDFs—this new workflow in Revit provides the ability to manage key electrical loads and distribution information without having to physically model any component. We’ve heard from designers that the requirements for distribution systems are defined and iterated long before it’s necessary or even desirable to create a physical model. As a result, it is now possible to conceptually define and connect loads and distribution system elements before starting model creation.

This new workflow provides a BIM-centric way to begin electrical power distribution design workflows, with a vision to connect these workflows to downstream workflows in the future.

We will cover these new features in detail in an upcoming blog post.

Revit 2023: Electrical Analysis

SYSTEMS ARE PRESERVED WHEN PHASES ARE USED

With the new version, the phases for MEP systems can now also be used.

When an element is demolished, it still retains its relationship to the system, so property values ​​such as system name, system classification, and system abbreviation are preserved.

Additionally, when elements are demolished (whether design ducts, cable ducts, cable trays, or fabrication elements), they retain their connectivity to neighboring elements, thereby supporting typical change behavior.

ENERGY ANALYSIS MODEL IMPROVEMENTS

As the need to measure and reduce building energy use and carbon emissions increases, we’ve made a number of fundamental improvements to Revit’s energy analysis model. Benefiting from this are Insight (for early-stage energy analysis / big picture), system analysis (for more detailed sizing and simulation) and gbXML export for third-party calculation solutions.

The primary focus of these improvements is accuracy, precision, and performance. This provides up to 3x faster Revit processing speed and eliminates memory limitations for very large models in Revit 2023.

ALTITUDE LABELING IMPROVEMENTS

Two highly rated MEP Idea Station entries relate to improving the ability to annotate heights on defined locations of MEP elements. The improvement addresses both design and manufacturing parts. Previously, the elevation of an element such as a pipe or duct was always relative to its reference plane. The enhancement in Revit 2023 provides the flexibility to define tags related to the level, project base point, or survey point. We’ve also improved the available built-in parameters for annotating straight elements of MEP systems to provide much more flexibility.

MORE IMPROVEMENTS FOR HVAC AND ELECTRICAL DESIGNERS

We added categories for plumbing equipment and mechanical controls (such as thermostats) to make it easier to define views that contain the expected items.

In addition, it is now possible in the family editor to rehost a connector, allowing you to move it within the family editor without having to redefine it.

Another requirement we implemented is adding a circuit number parameter for the Electrical Equipment category so that they can be included in labels, lists, and view filters like all other electrical and mechanical devices.

Finally, we’ve improved the way annotation symbols nested in a family are correctly retained in certain cases with the “Keep Annotation Orientation” option. There were cases where directional symbols (e.g. an exit sign with a directional arrow) could be displayed inconsistently between the top view and the ceiling view.

Above left and right: In Revit 2023 there are new categories for Mechanical Control Devices and Plumbing Devices.
Bottom left: Nested annotation symbols within families maintain proper alignment in recommended cases

MANUFACTURING IMPROVEMENTS

An improvement in manufacturing processes is that we are creating consistency issues associated with the development of control lever holes in duct fittings.

Solving this problem eliminates manual intervention in the process, streamlining the design for manufacturing and assembly operations.

Revit 2023 builds on the basis of Revit 2023.1 and adds improvements for the creation and editing of detailed mechanical models, making it easier to accurately create a ready-to-install model and, in particular, making it easier to deal with the complexity of sloped piping systems.

In 2023, additional capabilities improve the editability of manufacturing elements by applying similar capabilities that existed only for design elements in the past. These are:

  • Height controls for the end of elements to straight fabrication segments, making it easier to adjust the top and bottom height of an element
  • Relocate controls on in-line fittings such as branches and valves to easily adjust their orientation if needed.

PLATFORM IMPROVEMENTS

There are a variety of enhancements to the Revit platform that offer benefits to MEP users. One of our favorites is the new ability to move elements in 2D views, which addresses this long-standing Idea Station element:

“We need the ability to move annotation symbols into families to avoid overlapping symbols in our documentation. Perhaps the annotation could be attached to a widget (similar to the room calculation point) that would allow dynamic movement of the annotation in the project.” – Jerry

In addition, improvements allow marking moved items that address this idea station item:

“I would like to draw attention to the fact that we have Move Elements in several versions of the Autodesk Revit tool. This tool would be very useful for engineers to create isometric views of piping systems, cable trays, air ducts, etc., but we cannot mark moved elements!” – R_Mitin

Be sure to check out all the improvements construction productivity and documentation efficiency in Revit 2023.
