Forge Formats, Webinars and Fusion 360 Client API

I updated the WebGL and Forge introduction for BIM programming and its GitHub source for the presentations in the coming days at the RTC Revit Technology Conference Europe and the ISEPBIM Forge and BIM workshops at ISEP, in Porto, implemented two little curl wrapper scripts to help me list the supported file formats, explored why they changed and updated the hackathon webinar overview.

Solid From Bounding Box and Forge Webinar 4

I submitted the handout for my presentation on connecting the desktop and cloud for the RTC Revit Technology Conference Europe in Porto next month. I still have to finish my work on the roomedit3dv3 sample to demonstrate connecting the desktop with the cloud by enabling a real-time round-trip modification of the BIM via the Forge viewer; yesterday I integrated the transform viewer extension; now I have to hook up the socket.io messaging back to the Revit add-in to update the BIM – Create solid from bounding box – Forge webinar series 4 – Viewer...

Flipping a Section View and Forge Webinar 3

I already created a starting point for the new roomedit3d incarnation last week, in its own repository. This week, I agreed with Philippe to retain the new project in an own branch within the Forge boilerplate code sample collection. Hopefully, that will simplify keeping my BIM sample synchronised with any future updates make to that. Now I need to get started implementing and testing the actual viewer extension functionality itself. My main topic today is something different and purely Revit API oriented, besides the next Forge session – Flipping a section view – Forge webinar series... Read more →

The Birth of Roomedit3dv3 and Forge Webinar 2

Forge and AppStore Online Hackathon Webinars

For the fourth year in a row, we are hosting an online hackathon. In fact, it already started: the Autodesk App Store Forge and Fusion 360 Hackathon is running from September 1 until October 31. This time, the focus is on building apps using Forge APIs and Fusion 360 and extending the Forge ecosystem. Forge is a development platform – a set of cloud services that connects design, engineering, visualization, collaboration, production and operations workflows for all domains. At this early stage of Forge, many people may be interested in learning more about the Forge APIs with no obligation to publish an app; you are more than welcome to attend the free API webinars...

Now the calls for proposals have opened for both Autodesk University and the Forge accelerator in San Francisco... Read more →

What Can Revit on the Cloud Do For You?

Dear Revit API Add-in Developer Community, this is The Building Coder Post nr. 1400! 1400 is the number of different arrangements of four non-attacking queens on a 4×10 chessboard. I am using this happy special occasion to ask you an important and hopefully very popular question: What Can Revit on the Cloud Do For You? Would you like to run Revit on a Server? Are you looking for a Revit I/O, similar to AutoCAD I/O? What does Revit on the Cloud look like in your dreams? Could you make use of RealRVT, something similar to RealDWG, to programmatically access, create and modify a complete BIM without installing Revit? Read more →

How to Retrieve Dimensioning References

Several cases recently came up asking how to obtain references to programmatically create dimensioning elements. These hints expand on the recently discussed topic of creating dimensioning between family instance insertion points. They were raised by the following queries on how to retrieve suitable references for dimensioning: Dimensioning to family instance centre reference planes Dimensioning between a grid and an edge of a face Dimensioning to the wall opening wrapping location Before getting to that, I'll just add that I returned...

Picking Pairs and Dimensioning Family Instance Origin

We looked at various aspects of creating dimensioning in the past. There is still one glaring omission, though: how to dimension to a family instance origin point. Let's take a look at that, after quickly mentioning the official announcement of the movie matching game that we created at the recent Berlin hackathon. Actually, coincidentally, I discuss two topics today that are both completely and utterly dedicated to picking pairs: the Movie Match MasterY game, matching pairs of cards representing films,...

Attached Detail Groups and Inverse Relationships

I am still at the Berlin hackathon, working with the MovieMemory team... In between other tasks, let me mention the interesting discussion and solution by Revitalizer on the Revit API discussion forum to check for attached detail groups: Question: Can someone tell me, please, how I can find out if a Group (Type) has an Attached Detail Group (Type) via the API? Answer: A group of category OST_IOSAttachedDetailGroups has a BuiltInParameter.GROUP_ATTACHED_PARENT_NAME. This way, you will find matching Model groups. Response:... Read more →

Worksharing and Duplicating Element Geometry

I had two more interesting email conversations on Revit API questions, on add-ins in a worksharing environment and duplicating element geometry for detailing and fabrication. Actually, both of these topics have been discussed in the past, so a lot of the work I did was to dig out the existing material again to make these developer partners happy. Today I therefore have an opportunity to talk about the Revit API and nothing but the Revit API again for a change,... Read more →

Autodesk View and Data API Notes and Samples

Here is a summary of my notes from three presentations on the Autodesk View and Data API given by Cyrille Fauvel and Philippe Leefsma, in the two introductory workshops at HackZurich on Friday evening, October 10 and at HackaBxl in Brussels on October 17. Philippe also presented a very nice and absolutely minimal basic viewer sample in node.js demonstrating how to implement a private web service to obtain the authorisation token without exposing your key and secret in your JavaScript...

Brussels Hackathon, Pipe Wall Thickness and Voids

I received an email asking whether it is possible to determine the Revit MEP pipe element wall thickness, and also about the API access to voids in the family editor. Before getting to that, let me mention that I am now in Brussels at the Open Data Hackathon. Hackathon Open Data Brussels I arrived in Gent last night and returned to Brussels this morning for the Hackathon Open Data Brussels taking place today and tomorrow, October 17-18 2014. It is...

Past, Future, Frameworks, RevitLookup and Hackathon

Today, let me ask you to test my RevitLookup future-proofing update and mention a discussion on the use of the .NET 4.5 framework for Revit 2013, 2014 and 2015. I am sitting here writing this among the swans and gulls, squinting in the autumn sunshine on the shore of the Zurich Lake. Later, I visited the nearby Kronenhalle, a rather exclusive restaurant highly praised year in and year out by gourmet Christian Seiler, e.g. 2011, 2012 and 2014. With all... Read more →

Events, Again, and Creating an Extrusion Roof

Jon and Scott Wilson discussed some issues creating extrusion roofs on arbitrary planes in the Revit API discussion forum in the past couple of days. One neat spin-off is a simple little external command that shows the basic use of the NewExtrusionRoof method, so I took the opportunity of adding that to The Building Coder samples. Before getting to the details of that, here is a little update on the upcoming events: October hackathons and AU Germany Autodesk University in... Read more →

Hackathon, the Climate and my CO2 Footprint

Last week, I attended an interesting and rather sobering presentation on sustainability by Niko Paech entitled Befreiung vom Überfluss – liberation from excessive abundance – the German title is shorter and sounds better, for a change. That prompted me to have a look at my own CO2 footprint. This just happened to coincide more or less with the People's Climate March taking place simultaneously all around the world, including ten thousand participands in Berlin, Geneva and Zurich. Before getting to... Read more →
