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...

I took a first look at deep learning for question answering systems. Before that, I share some news on AU in Europe, thoughts on UI and innovation, and point out a useful Revit API feature for converting a Hermite spline to Bezier – Autodesk University in London – Rules of thumb for change agents – Invisible user interfaces – Conclusions from lexical analysis of top news stories – Converting a Revit Hermite spline to Bezier or NURBS – Lots of literature on deep learning...

I continued my activity in the Revit API discussion forum and had lots of interesting discussions there. One recent thread caused me to bring up a favourite topic of mine, on keeping things simple. I'll also mention two other less recent recurring questions – Distance between two points in a specific direction – Revit command-line switches – Keeping things simple with the Revit API – Dino pondering lengthening days...

Happy New Year to one and all! I had a great break over Christmas and New Year and hope you did as well. I continued checking into the Revit API discussion forum throughout and had several interesting discussions with the busy souls hanging out there – C++, audio, crypto and security – Prayer of the Mothers – Avoid remaking CAD content...

Most of the work of the year has been done, and it is time to settle down and clear out for the new. Tomorrow is the winter solstice, followed by Christmas and Yuletide, ending with the Twelfth Night. For me, this is a time of retreat, calm, reflection, and renewal of energy. Today brings a nice gift from Andrey Bushman – NuGet Revit API package – RevitLookup using the NuGet Revit API package – Creating a NuGet package from assembly DLLs – More NuGet packages...

Two topics today, on reordering viewports to determine their respective occlusion, and setting up a C++ Revit add-in project – Bringing a viewport to the front – Change the draw order of a viewport (bring to front) for cases when you need to use simplified duplicate of the same view for background, e.g., ceiling grid for example – Code clean-up – Setting up a Visual Studio C++ Revit add-in project...

I went back to answering way too many questions in the Revit API discussion forum yesterday. However, two other interesting topics also cropped up when I finally let go of that pastime, and I just finished a good book – The Sellout by Paul Beatty – IFC Ids and Open Shell – Forge Python scripts – – forge_authenticate_app – forge_formats – jprettyprint – Mainline...

I am happy to present a pretty comprehensive overview and explanation of the process of defining a shared parameter by Scott Conover. Question: What do I need to do to programmatically create a shared parameter? I would like to set the SetAllowVaryBetweenGroups flag on it. Answer: You create the details needed to define a shared parameter from ExternalDefinition. Existing shared parameter file entries can be read to become an ExternalDefinition in your code, or you can create a new entry in the current shared parameter file using the DefinitionGroup.Create method...

A Python Revit API question on renumbering viewports helps highlight two separate important programming aspects; I also add some other notes from the Munich Forge accelerator – Question – The need to regenerate – Use built-in parameters to access parameters – Forge accelerator and outage report – Added materials to 210 King model...

Some people have recently reported that they encountered models lacking the ProjectInfo project information singleton element. Apparently, it was possible in previous versions of Revit for a faulty or malicious add-in to simply delete this element. That obviously causes problems for other add-ins and Revit itself, who rely on its presence. Luckily, it is not hard to fix. Here is the latest discussion addressing this issue... Continue reading

The topic of how to determine all views in which a given element is visible has been discussed several times on the past, and a couple of viable solutions have been suggested. However, for large projects, performance becomes an issue. This question was raised again by Abba Lustgarten and Erik Eriksson in the Revit API discussion forum thread on finding views in which an element is visible (by geometry or actual visibility), with Erik sharing a View extension method IntersectsBoundingBox that helps alleviate the performance impact...

The Revit API is very simple. It is entirely event driven. Any and every use of the Revit API requires a valid API context. The most common and obvious way to get into a valid Revit API context – and the most commonly used event – is the one to launch an external command, which calls the IExternalCommand Execute handler method. Other important ones to be aware of are ApplicationInitialized and DialogBoxShowing, unconnected with any external command at all... Continue reading

Welcome to The Building Coder post number 1500! I returned safe and sound to Europe from Autodesk University 2016 in Las Vegas and recuperated from jetlag over the weekend. Today I discuss upcoming events, new simple samples to embed a Forge viewer in a web page or blog post, and strategies to embed a dictionary into the Revit database – DevDay Europe in Munich – AEC Symposium in New York – Embedding a Forge viewer – Storing a dictionary in the Revit database...

I recently mentioned the updated Revit 2017.1 SDK and its API enhancements. They are documented in full detail in the section Major additions to the 2017.1 Revit API of the Revit 2017.1 API help file RevitAPI.chm included with the SDK, which is also provided there in the separate stand-alone document Revit Platform API Changes and Additions.docx. For convenient, easy and effective web searching, here is the online version of that information... Continue reading

I returned from the Munich Forge accelerator, travelling back to Switzerland by train. For ecological reasons, I prefer to avoid flying whenever I possibly can. Last Friday was the deadline for submitting my Autodesk University handout, so that kept me busy. I still need to improve it a bit, and I hope a post-deadline update is feasible. I am presenting two classes, and I have a special discount to offer you. Lots of other things are happening as well – My classes at Autodesk University – $400 AU registration discount – Revit 2017.1 SDK – REX SDK FreezeDrawing sample – Determining the height of a column...

I am still in Munich supporting the one-week Forge accelerator workshop, returning back to Switzerland by train tonight. For ecological reasons, I prefer to avoid flying whenever I possibly can. Lots of exciting development is going on here, and we are making great progress. I have another important detail to report from the the RTC Revit Technology Conference Europe in Porto last week, and other little titbits to share as well – Use AddInManager and attach to process to edit and continue – Can I replace myself by artificial intelligence? – Autodesk Design Graph – Artificial intelligence recognises conversational speech – Good portable loudspeakers...
