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 →

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,...

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 →
