Pre-conference events at Autodesk University 2025

If you’re planning on attending AU 2025 in Nashville - and have an interest in software development, whether via code, low-code or no-code - then be sure to plan on being there for the pre-conference day on September 15th. There will be something for you. The Autodesk Platform Services team have organized their first Platform Leadership Forum, which will be held during the afternoon of the Monday before AU. You can find out specific details - including how to buy your ticket - in this blog post. If you’re more interested in rolling up your sleeves and building something... Read more →

Coming to Nashville

Last week prospective speakers who submitted class proposals for AU 2025 - which is being held in Nashville from September 16-18 - were notified whether the sessions were accepted or not. For this year's AU I'd submitted two classes. One was a look at various technologies we've been exploring to capture the human experience of the built environment, going back to projects such as the one we did with The Bentway, but also looking at more recent efforts involving crowdsourcing, EEG and VR. Unfortunately this class was declined. My other proposal was to repeat the session I delivered at... Read more →

DevCon Europe 2025 in Amsterdam - Day 0

This week I'm spending time in Amsterdam and London. On Sunday I headed across to Geneva airport and checked into a hotel that’s a gentle 10-minute walk from the terminal. It was the first time I’d stayed there, and I admit I was pleasantly surprised. The atrium was nice and I even had a cheeky sauna before sleeping. The alarm going off soon after 5am was a bit of a shock, but I felt rested enough. The walk across to the terminal was pleasant, considering the early hour. There weren't yet cars on the roads. Security was really quick,... Read more →

AU 2025 proposals, DevCon recording, Dynamo and Workshop XR updates

In Europe we’re about to celebrate the long Easter weekend, so things have been a little busy finishing up work in a number of areas, especially as soon after I’ll be heading across to the US for the rest of the month. I managed to submit two Autodesk University 2025 proposals - let’s hope that at least one of them gets accepted. I was also (apparently) the first DevCon presenter to record their session ahead of next month’s event. I’m very happy to have gotten that one out of the way before my travels. I haven’t had time to... Read more →

Learn about combining APS and WebAssembly at Autodesk DevCon Europe

While at the time of writing I’m not yet on the official speaker list, I’m happy to say that I will be presenting a session at the Autodesk DevCon that’s being held in Amsterdam from May 20th-21st, 2025. I’ll also be attending the Dynamo Hackathon on May 19th as a warm-up. My session is entitled “Supercharge your browser-based APS applications with WebAssembly” and will explore how you can take C++ libraries and build them into WebAssembly modules to bring impressive capabilities to your browser-based Autodesk Platform Services applications. Over the last few years I’ve spent quite a bit of... Read more →

Hackathons in Zurich and (soon) Amsterdam

On Friday I did my annual (well, it’s actually only the second time, but I get the feeling it’s becoming annual) trip to Winterthur for the Friday-night kick-off of this year’s AEC Hackathon Zürich. The focus of the first set of Friday afternoon talks was on the wood industry and its challenges - a fascinating topic to hear about first-hand. I was actually more interested by the second set of talks, which were focused on digitalization challenges, including a really nice session by Michael Drobnik from Herzog & de Meuron. As last year there were lots of hackers present,... Read more →

AU 2024 Days 0 and 1

On Sunday morning I headed across to Geneva Airport for my trip to Autodesk University 2024 in San Diego.The trip itself didn’t start very smoothly: I couldn't check in online - I suspect having two passports, only one of which has a valid US ESTA - meant that the airline flagged me for manual review. I really need to be more careful with my API (not the one I work with usually ;-) in future. Anyway, this check-in fail led to a cascade of irritations, from having to pay for a seat (to avoid being assigned a middle seat... Read more →

5 awesome VASA project ideas for the AU2024 Dynamo Hackathon

[My apologies for the click-baity title. I do actually have a list of 5 cool project ideas, if you scroll down the post. So it’s not completely dishonest, at least.] In the last post I mentioned a few classes you can sign up for (and that I’m directly or indirectly involved in) from the Tuesday to Thursday of the AU2024 week (October 15th-17th) in San Diego. I now have something to recommend for the Monday of that week, too! In the past we’ve often had pre-events at AU2024: I wasn’t sure whether there would be one this year or... Read more →

Using VASA with Forma via Dynamo

I’ve been talking quite a bit about our use of VASA inside Forma via our WebAssembly build of the toolkit (which is still not currently available publicly). I’ve done quite a lot of work to improve that particular prototype and I’m happy to say it’s shaping up nicely: the UX is much better than it was, for instance. I’ll be talking about our work on this at an upcoming Autodesk-internal tech conference, and as part of the preparation for this I’ve spent a few days building a pure Dynamo equivalent of the extension. VASA’s Dynamo package is available in... Read more →

My VASA demo from this week's Forma Hackathon

I’m now back from Oslo, and decided to record the demo I delivered there at the end of the Forma Hackathon (or something approximating it, as I used twice as much time as we were each allocated on the day). Here’s a photo shared by the event organizers of me talking: Here’s the video I recorded this morning: As I mentioned at the end of the video, the capabilities I’ve demoed inside this Forma extension could also be implemented using Dynamo for Forma. That’s probably something I’ll blog more about, at some point, if there’s enough interest. Read more →

AU 2023 class materials: Channeling Minecraft to Analyze Architectural Spaces with VASA and Dynamo

The recordings and other materials prepared for the two classes I helped present at AU 2023 are now available online. In today’s post I’ll point you to the first class, entitled "Channeling Minecraft to Analyze Architectural Spaces with VASA and Dynamo". This one was one of the first sessions of AU 2023, and had a very good crowd in attendance. Here are a few photos from the live session. Thanks again to Fernando Malard for snapping them. I already posted a quick summary of the content (without audio) - here that is again. Here is the material posted for... Read more →

Using VASA with Forma - Part 1

While preparing for one of my upcoming AU classes, I decided to explore how someone could use VASA - our Voxel-based Architectural Space Analysis toolkit - with Forma. Right now Forma is largely focused on conceptual design - taking into account the surrounding urban context - so this thinking was largely focused on how VASA might be used at the urban scale. This is something we’ve looked at before in the context of FormIt and Dynamo. While a tighter integration is likely to be possible at some point - I’ll talk a little more about our work on a...

Voxelising point clouds in Dynamo with VASA

Last week we saw a Dynamo graph that imports a point cloud from an ASCII-based format to specify the initial locations for a fun flocking simulation. This week we’re going to look at a graph that uses a similar import technique but rather creates a voxel model based on the point cloud: The main difference from the previous import code is that rather than returning a list of Point objects, we’ve tweaked the code to return 9 doubles for each point that are taken as triangle definitions. The little secret is that the triangle’s vertices are coincident: we use... Read more →

Flocking point clouds in Dynamo

I was thrilled to see a post by Long Nguyen over the weekend announcing his publication of a Dynamo package called WhatTheFlock – with full source code – that implements a Boids-like flocking simulation. This work is significant not because ornithologists will use Dynamo to predict or simulate murmurations (although that in itself is a fun thought) but because Long has demonstrated a valuable technique that might be used to implement other arguably more useful types of multi-agent simulation inside Dynamo. Long is using a background process to perform calculations before rendering the results into the Dynamo window. A... Read more →

Dynamo Office Hours showing Space Analysis and VASA

Last week Rhys Goldstein and I had a blast joining Sol Amour and Jacob Small during the Dynamo Office Hours session on Packages of Note, something I mentioned in a recent post. We spent some time stepping through a few samples for both Space Analysis and VASA, to give a rough sense of what’s involved in using each. Next week I’m heading over to Denmark for the first half of the week, where I’ll be attending the APS Sustainability Accelerator in Copenhagen. If you’re going to be in Copenhagen next week and want to meet up for a chat,... Read more →

An introduction to Space Analysis and VASA during the next Dynamo Office Hours

During the next Dynamo Office Hours – being held on March 9th, 2023 at 1pm EST – Rhys Goldstein and I will be joining Tiana Dame, Sol Amour and Jacob Small to talk about “Packages of Note”, which will include an introduction to the Space Analysis and VASA packages. I’m sure it’s going to be a fun event – it’s always a blast catching up with Sol and Jacob – and a good chance to learn about a few Dynamo packages developed and maintained by Autodesk. The focus will be on introducing the various packages – rather than going... Read more →

Explaining how path counting helps simulate natural navigation

Rhys Goldstein, an Autodesk Research colleague with whom I’ve had the great pleasure of collaborating on various projects, over the years, has written an excellent explainer article that has just been published in Towards Data Science. This is intended as a companion to our paper published in the Journal of Artificial Intelligence Research, something I talked about in this recent post. Firstly, though, a quick shout-out to Zach Kron, who kindly allowed an image of one of his watercolours to be used in the article; one he created with the help of Dynamo and the Space Analysis package, which...

Some exciting enhancements in Dynamo 2.15

Dynamo 2.15 was released into the wild, last Thursday (at least via Dynamo Core, if not yet Dynamo for Revit), and as Sol Amour says in his blog post, it is “an absolutely epic release”. I’d seen it flash by, but only sat up to take proper notice when Sol pinged me on Twitter to mention that includes capabilities inspired by Warnamo, a package I wrote to help keep track of warnings and errors in Dynamo. So I decided to dig into some of the new features – a great resource for this being the habitually comprehensive Dynamo release... Read more →

A paper on our space analysis algorithm in the Journal of Artificial Intelligence Research

I’m very happy to share the news that a paper authored by current and former members of Autodesk Research has been published in the open access Journal of Artificial Intelligence Research (JAIR). The paper is entitled “Path Counting for Grid-Based Navigation” and talks in depth about the algorithm developed to power the Space Analysis package for Dynamo. Here’s the paper’s abstract, to tickle your fancy: Counting the number of shortest paths on a grid is a simple procedure with close ties to Pascal’s triangle. We show how path counting can be used to select relatively direct grid paths for... Read more →

A new book on Innovation in Construction

The Autodesk Construction Cloud team kindly shared a post on LinkedIn, last week, about a project I participated in. There’s a new book from Springer on “Innovation in Construction” for which I contributed a chapter called “Cutting-Edge Practical Research on Generative Design, IoT and Digital Twins”. This chapter weighs in at 29 pages – of an overall 454 for the book – and here’s its abstract: This chapter explores two areas of research undertaken by Autodesk over the last decade and how they both have the potential to impact the construction industry. The first area relates to the Internet... Read more →
