Virtuous Reproduction, Research, Settings, Ontology

I have probably asked developers for reproducible cases a couple of thousand times by now. Let's discuss that and also return to the topic of how to research a Revit API problem in general. Finally, I'll point out a Revit 2017 API MEP electrical feature. Oh, and I continued my research into deep learning for a Revit API question answering system – Creating a reproducible case may well solve the issue at hand – How to research to find a Revit API solution – Access to cable tray and conduit settings – Getting started implementing a question answering system – First impression from IBM Bluemix – Open source QAS options – Building a Revit API ontology...

Exporting RVT BIM to JSON, WebGL and Forge

I am happy to say that I returned safe and sound to Switzerland from my travels for the Forge DevCon and Cloud Accelerator. Since then, I rounded off the hierarchical MEP system exporter to a JSON graph for interaction with it in the Forge viewer, worked on an update of the ADN JSON mesh exporter and helped my son Christopher getting started with C# scripting to drive audio effects for professional spatialized sound design for computer games – More TraverseAllSystems updates – CustomExporterAdnMeshJson updates – ADN JSON Exporter Alternatives to View RVT in WebGL – vA3C – The Forge Viewer – Getting started with Unity C# scripting – Opendesk at Autodesk Forge Accelerator Barcelona...

The pyRevit IronPython Script Library

Two weeks ago, Maltezc raised a question on the availability of a version of RevitLookup for Python. I am not aware of any Python version of RevitLookup, but you can certainly call into RevitLookup from RevitPythonShell. Maltezc pointed out the pyRevit IronPython script library. Ehsan Iran-Nejad, pyRevit creator and maintainer, now wrote a blog post describing this powerful and popular collection... Read more →

Forge DevCon, Spring, Impermanence, BIM Cloud

Spring is getting into swing, and new life is budding. I hope the same holds true for all your development efforts and visions of the future. Not everything is budding into new life, though... part of existence is passing away, as well. One of my dearest school classmates and closest friends of my youth, Prof. Dr. Lorenz Poellinger, unexpectedly passed on. The two of us travelled together for several of months, climbing and hitchhiking... Read more →

Entitlement API, Trial Period and Floating License

I had an exciting weekend with ski tours under challenging weather conditions around Oberalppass, Sedrun-Andermatt, skiing on Piz Maler on Friday, piste in a snow storm on Saturday, and climbing Piz Cavradi via the Maighelshuette Sunday morning in splendid conditions, with 50 cm of fresh powder snow for the descent. Here is today's Revit news for you – Trial period, floating license and the Entitlement API – SketchUp Plugin for Grevit – EMEA ADN team meeting in London... Read more →

tbc – The Building Coder Source and Index on GitHub

Developers frequently lament bad search functionality on Typepad-hosted blogs. Furthermore, it is always handy to have an offline local copy of any kind of important documentation you need to consult regularly. With a local copy of The Building Coder source text, you can use your standard system tools to search and index locally in any form you like. Finally, wouldn't it be nice to have a simple line-by-line index of all The Building Coder blog posts ever published? – Publishing The Building Coder source and index on GitHub – GitHub size limitations – Alternative blogging platforms – Fork and clone to create your own local installation – El Perro Semihundido by Goya...

From Hack to App – OBJ Mesh Import to DirectShape

I already took a couple of looks at the DirectShape element in the past: DirectShape Performance and Minimum Size DirectShape versus Families, Category and Texture A much deeper investigation was prompted by Eric Boehlke of truevis.com, knowledgeable in architecture and above all in photogrammetry. Eric visited the DevHack at Autodesk University in December 2014. Together, right there and then, we put together a prototype Revit add-in that reads an OBJ file and creates a DirectShape element from it. Eric continued... Read more →

.NET Open Source and Visual Studio Community

Steve Mycynek of the Revit Development team pointed out an important update on .NET and Visual Studio: As you may know, one frustration faced by Revit API developers is the lack of debugging support in the free Express versions of Visual Studio. They do not support debugging DLLs against an EXE host or attaching to a process, which is exactly what we require to debug a Revit add-in loaded into Revit.exe (except by resorting to tricks, used, e.g., for the...

DirectShape versus Families, Category and Texture

Let's begin this week with a discussion of several aspects of direct shapes: Direct shapes, part families and application porting DirectShape categories DirectShape texture assignment Direct Shapes, Part Families and Application Porting Question: I am looking for some guidance related to porting my application to Revit. I have a parametric part engine that lives outside of Revit with a large set of existing library content. It would be very costly to rebuild from scratch using the Revit Part Family editor...
