I hope you are happy and healthy and enjoyed your Easter eggs! During the holiday, I updated RevitLookup for Revit 2021, and Harry Mattison added his multi-release building enhancements into the main solution as well – Revit 2021 add-ins require .NET 4.8 – RevitLookup flat migration to Revit 2021 – Support for multi-release building...
Here are two important utilities, one eagerly awaited, the other a nice surprise: the updated REX and Structural analysis SDKs and a powerful
await wrapper for the Revit API external event
– REX SDK and Structural Analysis SDK 2020
– Standard approach
– Revit.Async approach...
Getting started material and questions galore. Please search before asking, and work through the available material before trying to shoot yourself in your feet, knees, and elsewhere – Marko's plugin development playlist – Overview – Table of contents – Getting started with an API script – Getting started with a macro – OBJ mesh import with materials – 2D Booleans in the Revit API...
await external event wrapper!
Communicating from outside with Revit is often better replaced by the Forge Design Automation API for Revit.
However, it is also possible to make use of Revit as a server in a limited way via an external event
– Communicating with another process
– Autodesk open positions...
I successfully made it from Switzerland to Paris and the Forge accelerator in spite of the French strikes. My only worry is how to get back again tomorrow. Again, the train I have booked has been cancelled. Meanwhile, let's take a look at – DA4R room support and new samples – Effective filtered element collection...
Today is my birthday, so I am trying hard to work less. Very kindly, Alexander Ignatovich provided a gift for the day in the form of a new external command CmdElectricalLoad in The Building Coder samples. showing how to retrieve the value of the `Load` column in the electrical system browser for a specific fixture family instance...
This is The Building Coder post number 1800, in its eleventh year of existence. We celebrate by highlighting the integration of a 3D geometry and model viewer in a Revit add-in with a solution making use of several interesting techniques, including the use of IPC for add-in disentanglement from third-party library dependencies and a new custom exporter implementation for OBJ. This issue was raised in two discussions, on a plug-in that displays Revit's 3D window content and using a geometry viewer in a Revit add-in to preview results...
A search for Revit API related books, a very nice new Revit API starter kit, a richer and much more complex literary AI-related book, and a quick bottleneck steel guitar blues recording not related with any technical topic whatsoever – A very basic book on Revit API – Revit API starter kit – Machines like me – Bottleneck blues guitar...
Please note that the European Forge DevCon in Darmstadt is looming imminent. Furthermore, here are some notes on two recent Revit programming discussions and a pointer to some of the top-rated online classes – DevCon Darmstadt – Personal DevCon invitation from Jim Quanci – Sun direction adjusted for project true north – Reading an RVT file without Revit – The top 100 free online courses...
An important Revit add-in requirement regarding Transport Layer Security (TLS) settings, a short note on accessing PDF image data from an import instance, and an update of the Collada DAE custom exporter for use in Revit 2020 – Required Transport Layer Security (TLS) settings – Accessing imported PDF image data in Revit – Custom Collada exporter updated and fixed...
Yesterday, I implemented a new add-in, RoomVolumeDirectShape, that creates
DirectShape elements representing the volumes of all the rooms
– Request to display room volumes in Forge SVF file
– RoomVolumeDirectShape functionality
– Retrieving all element properties
– Converting a .NET dictionary to JSON
– Complete external command class
– Sample model and results
– Challenges encountered underway
– Cherry BIM Services
– On the value of the "Loss Method" property
– AI-generated talking head models...
The pyRevit rapid application development environment can be used for the entire add-in lifecycle, supporting rapid debugging, testing and deployment as well. I successfully implemented invoking an external command defined in a stand-alone Revit plugin assembly from pyRevit! It's proving extremely useful...
Today, yet another introduction to Forge, a simple issue of setting the level of a floor element, and the much more complex one of gaining freedom and total independence via IPC – What is Forge? – Changing the level of a floor – Entanglement can be hell – CefSharp entanglement – Disentanglement and independence via IPC – Beer-ware license...
Today I discuss (once again) an important performance aspect of Revit element filtering, a Python script for tagging JPEG images with EXIF data, prompted by a recent ski tour, and three other interesting topics that caught my eye – Slow, slower still and faster filtering – Python JPEG EXIT filename tagging – TED talks and population growth – Objective reality does not exist – Artificial intelligence judge...
As usual, I have been much too active in the Revit API discussion forum recently and worked too little for my taste here in the blog. Here are some of the recent items that I want to share plus a few pictures from my latest mountain outing – Marat's shapka ushanka and Balmer's Graetli – Naveen is a top solution author now – Revit et BIM en Français – Tree view performance optimisation – Underture...
Some interesting settings are stored in and can be modified by editing the Revit ini file. Peter @pgerz pointed out yet another possibility in his answer to the Revit API discussion forum thread on adding a project template to 'New Project' via API. Question: I noticed the UI method for adding a project template to the 'New Project' dialog on the Start Window by going to Options > File Locations and clicking the little plus symbol...
