Using Refinery to optimise a Dynamo graph using Space Analysis for pathfinding and visibility

As a follow-up to this recent post, I decided to add a couple of metrics to the previous graph and try it out with Refinery. And here’s the updated graph for you to try for yourselves. The first metric relates to the pathfinding capability, and I’ve called it “Access”. There are a few things going on, here: for sure we want to measure the shortest average path, but also to disqualify (or at least penalise) designs that don’t have paths to all of of our points of interest (i.e. the corners). But I also wanted to weight the results... Read more →

Dynamo Space Analysis and Revit 2020’s Path of Travel

Many of you will have been happy to see the extent of the features announced last week for Revit 2020. It’s great to see Dynamo 2.1 integrated, for instance: It seems the Dynamo version is being tied specifically to Revit, which is an interesting development. I assume this is driven by the need to manage complexity of end-user environment configuration, but I do wonder whether it will impact the ability for users to absorb changes delivered by the Dynamo team. But that’s the trade-off between control and flexibility, I suppose: we’ll see how it works out. In addition, the... Read more →

Using the Space Analysis package for pathfinding and visibility in Dynamo

I’ve been meaning to create a post introducing the use of the Space Analysis package for a few weeks, now, but with various trips it’s been impossible to find the time. Anyway, here it is, at last. You can start by downloading the graph we’ll be walking through in this post. Here’s a picture of the graph, with its graphics generated. The graph is fairly simple: it loads some geometry from an SAT file that we’ll use as the definition of our barriers for the SpaceLattice. I’m using an SAT file we posted with the campus layout example that... Read more →

A great video introduction to Project Refinery

Our friend in Munich, Jacqueline Rohrmann, has recorded a fantastic 24-minute introduction to Project Refinery and posted it to her YouTube channel under her That BIM Girl pseudonym: I really like the way Jacqueline steps through how to get started with Refinery, but also “does the math” and validates the results generated by Refinery for a simple example. Very cool. I’m hoping Jacqueline will find the time to take a look at our Space Analysis package for Dynamo and post a video on getting started with it: I’d love to see Jacqueline’s thoughts on the package, delivered in her...

The first Dynamo Hackathon

What. A. Week. The first day of the world’s UK Dynamo User Group’s first Hackathon was an appropriate way to finish off a hectic but super-rewarding week. [Correction: it seems I misunderstood something… there have been other Dynamo Hackathons, apparently. Sorry about that.] I woke up early, this morning, and took a stroll around Hyde Park. I checked out from my hotel, picking up my cufflinks, on the way. (In a random episode during check-in, the afternoon before, I’d lent them to a fellow hotel guest – who was dressed to the nines for a charity event but had... Read more →

Generative Design for AEC at OTx EMEA

It was a fun (and slightly hectic) 16 hours in Barcelona. After heading back to the hotel from the OTx awards dinner – and whipping out a quick blog post – I got up and enjoyed the view from the 26th floor for a few minutes… … before heading across to the last day of OTX (One Team eXtension) EMEA, and the second day of the Generative Design for AEC track. This second day was the first “mixed” track – meaning both sales- and technically-oriented, as the first day had been purely for technical attendees – so it started... Read more →

Autodesk’s Automotive Innovation Forum 2019

This is “one of those weeks”, with presentations in Munich on Wednesday, Barcelona on Thursday and London on Friday. I haven’t had a week like this since the old DevDays tours. The good old days! I arrived on Tuesday night at Munich Airport. Wednesday’s event was the Automotive Innovation Forum in Munich. It’s the first time I’ve attended this event, and it proved to be very interesting: around 560 automotive customers came to the Hilton at Munich Airport to learn about our automotive-related offerings (primarily Alias and VRED but also our generative design tools). The day opened with various... Read more →

The Living vs. The Dead: using Generative Urban Design to prepare for the zombie apocalypse

Over the last few months I’ve been working with my colleagues in The Living to add important – but still slightly speculative – capabilities into the Generative Urban Design tool we’ve been working on for Van Wijnen. The opportunity presented itself back at Autodesk University 2018, when Lorenzo Villaggi and I were discussing the state of the world over a few beers. It seemed absolutely clear, from our perspective, that given where we are today – thinking about global politics, the climate and civil liberties – it seems inevitable that the next thing to hit will be the zombie...

Generative Design workshop for Sweco in Stockholm

On Wednesday morning I headed up to Stockholm to participate in a Generative Design workshop for Sweco. It’s been a long time since I’ve been to Sweden, so it was a fun coincidence that I already had a little taste of the country as I took my train to Zurich airport from Neuchatel. IKEA Switzerland has a special vending machine moving between the larger Swiss railway stations as part of a promotional event. It was a bit of a shame the machine was out of order, but these things do happen. The flight to Stockholm Arlanda was uneventful, and... Read more →

Daily Dynamo Sandbox builds and Refinery v0.4.44

There’s a lot happening this week in the world of Generative Design for AEC at Autodesk. Aside from the Space Analysis package we announced, there’s interesting news from both the Dynamo and Refinery teams. The Dynamo team has kicked off their daily build process once again, this time focusing on Dynamo Sandbox builds. This is very interesting news for me, and probably for other people working on GD projects outside of Revit: I use Dynamo Sandbox to do the majority of my GD-related studies – usually by starting the executable found at %programfiles%\Dynamo\Dynamo Core\2\DynamoSandbox.exe that’s installed with Dynamo for...

The Space Analysis package for Dynamo and Refinery is now available!

As promised last week, Autodesk Research has now posted v0.2 of our Space Analysis package to the Dynamo Package Manager. This version contains nodes for pathfinding as well as for visibility analysis. Both implementations work via a common SpaceLattice object – basically a 2D grid with diagonal connections – that can be used to drive both algorithms. In reality you may end up having multiple lattices – as pathfinding may be working with “barriers” that don’t affect visibility – but the node you need to use is the same. We had posted a previous version with just pathfinding, but... Read more →

Sneak peek at pathfinding

A quick update before a larger unveiling next week… We’ve made solid progress with implementing the grid-based capabilities of the SpaceAnalysis package. All being well we should have an “official” version available early next week. This release will contain pathfinding – based on Djikstra’s shortest path algorithm, working on a grid with the size and resolution of your choice – as well as the ability to test visibility – using the same grid for an Isovist-like analysis. We have a version already posted via the Dynamo Package Manager (ssshhhh!), but we’ve gone through and rationalised a bunch of the... Read more →

Last chance to apply to join the first Dynamo Hackathon in London

On April 5th-6th, 2019 in London, the UK Dynamo User Group is holding its first ever Dynamo Hackathon. Several members of the Dynamo and Refinery teams will be there, as well as yours truly (I’ll only be there on the 5th, though, as I have family commitments over the weekend). If you’d like to participate, you do need to move quickly: today (March 19th) is the last day that submissions will be accepted. (This deadline really crept up on me: I’ve been meaning to post about this for the last week or so, but was busy on other things…... Read more →

The first Forge Accelerator in Dublin

Last week I thoroughly enjoyed a short week at the first Forge Accelerator in Dublin. (It was short – for me – because I arrived on Monday afternoon and headed home, already, at Thursday lunchtime.) It was only my second time ever to visit Ireland, but the second in just a few months, and my next trip across is already planned for June (if one doesn’t happen sooner). I was staying across the River Liffey from the office, and enjoyed the stroll across a convenient pedestrian bridge, even if the wind and harmonic resonance sometimes made me question the...

Adjusting zoom to fit in the Forge viewer

A question came up during this week’s Forge Accelerator in Dublin that I thought would be of broader interest. It related to the fact that the Forge viewer’s default behaviour when you double-click the background and perform a zoom-to-fit isn’t always desirable. In this case the developer was fine with a zoom-to-fit being performed, but felt the resultant view wasn’t a good enough fit. Here’s the default zoom level on double-click in Dasher 360, for instance: As you can see the model remains quite far from the camera. The good news is that debugging into the Forge viewer source,...

At the Forge Accelerator in Dublin

After having spent a great few days with the Toronto team, I headed home on Friday afternoon. I did have a little bit of “fun” getting home, though: firstly the UPExpress going from Union Station to Pearson Airport stopped – ostensibly waiting for the right signal – for about 30 minutes. It wasn’t a big deal for me, thankfully: I’d left some buffer in my schedule, so still had a little time to wait at the airport. While I did so, for some reason I checked my downloaded Netflix content… none of it played: I kept getting an obscure... Read more →

Visiting MaRS

I seem to spend quite a bit of time, these days, talking about the new Autodesk office in Toronto. I did visit one part of the office when I came through in July 2017 – on our world tour – but people hadn’t, at that point, fully moved across from the former 210 King St East office. So this week was – somewhat surprisingly – the first time I’d actually seen the generatively-designed office space first-hand. Crazy. I’ve been staying in the Chelsea Hotel – apparently the largest hotel in Canada, with about a thousand rooms – which is... Read more →

Heading to Toronto

I’m at Zurich airport, waiting for my flight to Frankfurt, from where I’ll head onwards to Toronto. (The way over has a stop as the daily direct flight leaves too early for me to comfortably take… at least I can take the direct flight home – a red-eye – on Friday night.) The main purpose for this trip is a team offsite on Thursday, but I’ll be spending as much time as I can on Wednesday and Friday working with my Toronto-based colleagues. There are a few Dasher 360-related tasks I need to move forward, while I’m there, and... Read more →

Building buzz

I’m on holiday with my family, this week, enjoying the Bernese Oberland with family and friends. In Toronto – where I’m heading next week – my team-mates are busy trying out the 2D path-finding component I talked about in the last post. Now that Simon Breslav has wrapped the C++ path-finding module created by Rhys Goldstein – building a .NET wrapper and using it from Dynamo – he’s started using it to implement a version of the “buzz” metric The Living used for Project Discover. Here’s a sneak peek of how it currently looks with one possible layout of... Read more →

Interested in space analysis for Dynamo and Refinery?

Over the last few weeks colleagues in Autodesk Research have been building the foundations for a space analysis package that can be used for generative design workflows in Dynamo. We’d love to hear from you if you’re interested in taking it for a spin. But first, a little background… We’ve known we’ve needed to get better performance when analysing 2D and 3D spaces since embarking on the original layout of the new MaRS office in Toronto as part of Project Discover: the approach we had worked well – as I think is clear from the results of the project...
