Build your own SoundSystem: Space Analysis now supports multi-source acoustics

After somehow adding support for acoustic analysis to the Space Analysis package, Rhys Goldstein has taken it to the next level by adding support for multiple sound sources. When Rhys first did this he was a little surprised by the results he was seeing. There were some really interesting interference patterns at the boundaries between sound sources: Find this example at %appdata%\Dynamo\Dynamo Core\2.3\packages\SpaceAnalysis\extra\spaceanalysis-acoustics-06-six-points-voronoi-pattern.dyn. (You may need to change the Dynamo version number.) Rhys dug into the field a little more deeply and came across this interesting blog post that highlights the possibility for sounds of similar frequencies to interfere... Read more →

A new release of Refinery with tighter Revit integration and output constraints

A big – and welcome – update has just been dropped by the Refinery team. I’ve been waiting for this one, in particular, as I expected it to work better with the MaRS graph. (I’m happy to say that it does – more on this later.) The big ticket item in the v0.35.0 (still Beta) release is an integration with Revit that doesn’t require users to open Dynamo. It’s at this point that you can probably hear a collective “say what?!?” from existing Refinery users (such as myself, I might add): until now you’ve been very exposed to Dynamo... Read more →

Ramping up for Autodesk University 2019

The summer is pretty much over (boo) so it’s now time to start thinking about AU (yay). If nothing else it’s a welcome distraction from the craziness of UK politics (which I’m following from Switzerland, making it presumably slightly less intense than it is for most of my fellow Brits). Before getting more into specific AU plans, a quick reminder that registration for AU 2019 – and the Forge DevCon that precedes it – is open. The Monday pre-conference (this year’s is on November 18th) is always chock full of great information: I’m very much looking forward to attending... Read more →

Does Dynamo (and Revit) crash for your projects? We'd love to hear from you!

An interesting post over on the DynamoBIM forum was brought to my attention, and I felt it worth reproducing it here. The Dynamo team have found a way to avoid the need to manually dispose of geometry when creating it from Python or C# – as many package developers do – which they believe will help avoid a whole lot of crashes when working with large geometry sets. If you suspect you’re hitting these issues – due to your own code or a package you use – and can help test this new capability, we’d really appeciate you getting... Read more →

Using a view cone for targeted visibility in Dynamo with Space Analysis

I feel as though I’ve been neglecting this blog: I’ve barely managed a post a week for several weeks, now: partly because of family holidays, but also because I’ve been heads-down on Dasher 360, working on a number of cool new features as well as shoring up some of our older code. Anyway, the kids are now back at school and I expect to have a lot more to talk about during the remaining months leading up to AU 2019. For now I wanted to share some information about the Space Analysis package. Today’s post takes a look at... Read more →

Week 1 of the Generative Design for AEC Intensive Residency in Toronto

While I was having fun in Paris, the participants at our first Generative Design for AEC Intensive Residency were having their own fun in Toronto. Here’s a quick recap of the rest of the first week… Tuesday was all about Dynamo and Refinery. Our Product Managers for each presented their technologies and dug into some specifics on how to use them. First up was Sol Amour, PM for Dynamo. Next was Lilli Smith, PM for Refinery. Simon Breslav then dove more deeply into Project Rediscover (something I’ll myself be talking about at AU 2019 in Las Vegas, so I’ll... Read more →

Generatively Paris

Yesterday I hopped on the TGV Lyria in Bern to head across to Paris for a meeting with a large customer who was interested in learning more about generative design. It was nice to be heading back across to Paris – especially just before the summer break – as I have very fond memories of my year studying just south of the city. On arrival at Gare de Lyon I decided to walk for a couple of kilometres to stretch my legs after five hours in the train, to see part of the city I didn’t know but also... Read more →

The Generative Design for AEC Intensive Residency kicks off in Toronto

Yesterday marked the first day of a very special 2-week event being held in the spiritual home of Generative Design for AEC – at least from Autodesk’s perspective – our new office in the MaRS district of Toronto. (In fairness the spiritual home is probably where The Living work in New York, but the MaRS office is at the very least an important temple. ;-) Over the next fortnight 7 teams from 3 continents – from both industry and academia – will be using Dynamo and Refinery to implement generative workflows at various architectural scales. We’re expecting the participants... Read more →

A quick update on various projects

Things are heating up in the Systems Research team (and not just because it’s summertime). I’ve been digging into the Dasher 360 codebase, this week, to add better support for “equipment” sensors – which have multiple sensors and data feeds coming off them for a single unit – particularly with respect to tooltips. As an example, here’s a ubertooltip summarising recent data coming off a Mazak 5-axis mill in our Advanced Manufacturing Facility in Birmingham. There are devices in the AMF that have more sensors – up to 60, in fact – but those feeds were less visually interesting... Read more →

Say what? Acoustics in Space Analysis?

You heard right. Somehow our resident simulation hero, Rhys Goldstein, has found a way to approximate acoustic analysis using the same fundamental data structures he used to implement both pathfinding and visibility. Simon Breslav has built the core C++ library into the Space Analysis package and has posted it to the Dynamo Package Manager as version 0.3.0. Here’s a screenshot of the feature in action: This graph has two point sources, which can be combined by either union or intersection: for most scenarios I’d imagine it would be more useful to use union, which will aggregate multiple sources… we...

A nice introduction to DynaMaps and Space Analysis by That BIM Girl

The awesome Jacqueline Rohrmann – who you may know as That BIM Girl – has recorded a great “virtual unboxing” video introducing a couple of useful Dynamo packages, DynaMaps (which has it origins from the Dynamo and Generative Design Hackathon held in London in April) and Space Analysis. Jacqueline shared the video with me earlier this week – when we were both at the Dynamo Day in London, and then AU London 2019 – but I hadn’t found the time to watch it until now. She’s done – as ever – an amazing job at presenting things in an... Read more →

AU London 2019

It’s been a crazy (but very cool) few days here in the UK and Ireland. It started with the pre-event (or perhaps the pre-pre-event) of the annual Autodesk football tournament in Dublin. We didn’t win, but we had an absolute blast. I’m definitely looking forward to next year’s event in Barcelona! On Sunday a group of us flew from Dublin into Heathrow: the others headed directly into town, while I stopped at a friend’s for dinner in Windsor. Heading into town, later on, I saw a message from Jaime Rosales: the Circle & District lines were completely closed, so... Read more →

Project Rediscover is now available for download

I’m happy to announce that the recreation of Project Discover for Dynamo – what we’ve been referring to as Project Rediscover – is now available for download. I should point out that this is a first cut of the graph, and is definitely going to evolve over time: it’s a complex beast that uses advanced techniques – particularly on the metric calculation side of things – that we know we have to improve over time. But we did want to put this out there as an Alpha (or pre-Alpha) in advance of Autodesk University London 2019 to let people... Read more →

Dynamo and GD events in London and Toronto

There are some very interesting events scheduled for the coming weeks. Just prior to next week’s AU London 2019 – itself an event that will be heavy on content for computational and generative design, this year, including a talk by Lorenzo Villaggi and myself – there’s a Dynamo Day being hosted in London by the UK Dynamo User Group (or #UKDynUG) on Monday June 17th. There are four day-long workshop streams tailored for various needs… Dynamo Intro plus Geometry Dynamo Intro plus Data Dynamo Power Up Dynamo Dev Day … followed by an evening user group session with a...

Capturefinery is live on the Dynamo Package Manager!

(If you’re asking yourself “what’s Capturefinery?” then I suggest reading these posts first. TL;DR: Capturefinery is a tool for capturing screenshots of the various runs in a Refinery study and compiling them into animated GIFs for sharing via social media or including in customer presentations.) Firstly, a huge thank you to my partner in crime – and the first (so far only?) user of Capturefinery – Simon Breslav. He’s been kicking the tyres and giving very helpful feedback that has steered the development of this package. He very kindly tells me he likes it a lot – I hope... Read more →

More Capturefinery enhancements

I’m happy to announce that the Capturefinery package for Dynamo (and Refinery) is finally ready for posting to the package manager! My main misgivings – stopping me from posting it sooner – had been around the basic UX (fixed in the last update) and the fact that the tool requires (or required) the system to basically be dedicated to the capture operation. These have all now been addressed. Here are the enhancements I made today: The graphics are now captured via the Dynamo API, rather than via the OS (i.e. the screen) This means you can keep Dynamo minimised... Read more →

Capturefinery updated to help track down errors

I talked recently about a Dynamo view extension I created to capture presentation graphics (primarily animated GIFs) from the entries in the “hall of fame” of a particular Refinery study. This has been super-useful, internally, but not just for creating fancy graphics. Early on we realised that it was a great way to identify problems in Dynamo graphs: we could see the occasional error state (with the yellow text at the bottom left of the screen) flash past, indicating that a Dynamo run had completed with warnings and/or errors. Presumably the errors haven’t stopped the metrics from being evaluated... Read more →

Introducing Capturefinery, a Dynamo package that creates presentation graphics for Refinery studies

A few weeks ago I posted a GIF on Twitter that showed a few images from an earlier version of the Project Rediscover graph. I created this in a very manual, low-tech way: firstly, I selected a number of designs in Refinery, one-by-one, took a screenshot of each and then used GIMP to build an animated GIF. (This used to be very easy to do with previous versions of OS X, by the way: the Preview tool allowed you to drag images across into a GIF file and create new frames, and you could then use GIMP to adjust...

Parallel operations in Dynamo and Refinery

I’ve mentioned this topic a few times in recent weeks, so it was really time to sit down and put pen to paper (or fingers to keyboard). This one was a lot of fun to dig into, and I think the results will be of interest to people. Parallelism is something that I’ve been tracking since my studies during the 90s: I remember programming transputers using a programming language called occam, way back when. I was really happy when – around a decade ago – Microsoft got serious about tackling asynchrony and concurrency with F#’s Asynchronous Workflows and the... Read more →

Presentations and awards from the Dynamo and Generative Design Hackathon in London

A video of the final project presentations and the awards ceremony from the recent Dynamo and Generative Design Hackathon in London has been posted to YouTube by the UK Dynamo User Group. It’s a great way to get a sense of the various projects at the event, something a number of people have asked me about. I was only really there to help kick things off and answer initial questions about using Dynamo with Refinery to implement Generative Design workflows, so it’s fantastic to see how things ended up. If you have follow-on questions about the various projects, I... Read more →
