Wall Elevation Profiles in The Building Coder Samples

Last week, I presented a stand-alone command by my colleague Katsuaki Takamizawa to retrieve wall elevation profiles. His implementation provides a nice little example of using the ExporterIFCUtils.SortCurveLoops method and differentiates between outer and inner loops. It can be used in almost exactly the same way as the first wall elevation profile implementation presented in 2008. After publication, Katsu-san and I discussed what to do next and unearthed a couple of interesting aspects: Response: Thank you very much for publishing... Read more →

Isolating Elements of a Given System

I am very glad to present another post contributed by Victor Chekalin, or Виктор Чекалин, who already shared many valuable insights and in-depth Revit API research in the past: On the Russian developer forum, the user goblya asked an interesting question. He needs to hide all elements except those that belong to a specific given system. There are some interesting moments in the solution. The main idea is to create the filter, assign this filter to the active view and... Read more →

Getting the Wall Elevation Profile

I am back from the vacation in Italy, which I enjoyed very much, especially another visit to the wonderful coast of Amalfi. To quickly share an interesting new result using the Revit API, here is a solution by Katsuaki Takamizawa to retrieve the wall elevation profile. It also provides a nice little example of using the ExporterIFCUtils.SortCurveLoops method that we just recently documented. Says Katsu: I created some sample code for finding the wall elevation profile and determining its outer... Read more →

Vacazione in Sicilia

I'm off for a short vacation in Sicily. No computer, sleeping out. I wish you lots of fun and success with the Revit API, and myself some nice nature, good long walks, and deep relaxation. And good coffee. Ciao! Read more →

ExporterIfcUtils Curve Loop Sort and Validate

Joel Spahn raised a pertinent question on sorting face loop edges that was kindly picked up and answered by Scott Conover and Angel Velez from the Revit development team: Question: It would be nice to know exactly what the following methods do: SortCurveLoops: sorts a set of curve loops such that outer and inner loops are separated. Remarks: Outer loops are separated and inner loops are grouped according to their outer loop. Loops are assumed to be non-intersecting, and there... Read more →

The Future – أنا تشارلي

In these troubled times, I was struck by this WWI poem sent out for the New Year by my bookshop and literature friend Franz Metzler: L’Avenir Soulevons la paille regardons la neige écrivons des lettres attendons des ordres Fumons la pipe en songeant à l‘amour les gabions sont là regardons la rose La fontaine n’a pas tari pas plus que l’or de la paille ne s’est terni regardons l’abeille et ne songeons pas à l’avenir Regardons nos mains qui sont...
