Introducing VASA, a tool for Voxel-based Architectural Space Analysis

I’ve been hinting about this for a few weeks now, but today is (very excitingly) the day for the big unveiling. My colleague Rhys Goldstein has been working his magic, once again, taking the algorithms he developed for the 2D Space Analysis package and applying them to 3-space. If you were impressed by Space Analysis, what we’re showing now may just knock your socks off. The new package is called VASA, which stands for Voxel-based Architectural Space Analysis. It’s available today for download from the Dynamo Package Manager. It’s worth unpacking a couple of terms, here: voxel-based means VASA... Read more →

A minor update to Space Analysis (2D), and getting ready for 3D!

This week I’ve been getting my Revit installation working again – it had been a while since I’d used it, and it was overdue an upgrade from 2021 to 2022 – mainly because I have to publish a couple of new packages (or package versions) to the Dynamo Package Manager. The first is a minor update to the Space Analysis package, taking it from version 0.3.3 to version 0.4.0. There is a breaking change, however, in that people using the Visibility nodes from Python may have to modify their code to use the correct (newly added) namespace. We only... Read more →

Dynamo 2.12, MaRS v3 and the future of Space Analysis

The latest update to Dynamo Core (which for now you can use via Dynamo Sandbox) has some really interesting enhancements, both in terms of usability and performance. Check out Sol Amour’s two blog posts that introduce Dynamo Core 2.12. As it had been a while since I’d tried the MaRS graph in a new drop of Dynamo, I went ahead and loaded it. I immediately noticed a couple of things: it was referencing an old, now-deprecated version of the Solar Analysis package, so I updated to the latest & greatest version on my system and then reloaded the graph...

Creating additional documentation for Space Analysis in Dynamo 2.11

I mentioned last week that Dynamo 2.11 allows package owners to add additional documentation for their nodes via the enhanced Documentation Browser. I decided to give it a try, and then decided to test the possibilities around automating the process. Here’s the idea: the Space Analysis package comes with 15 different samples showing how to use its various nodes. These are all hidden away in the %appdata%\Dynamo\Dynamo [Core|Revit]\2.x\packages\SpaceAnalysis\extra folder, so lots of people don’t know they exist. What if the Documentation Browser told you about the samples that use a particular node when you pull up its help? Here’s... Read more →

Dynamo Core 2.11 (and Dynamo 2.10 and Generative Design in Revit 2022)

It’s that time of year, where our engineering teams release the primary annual updates to our products. AutoCAD 2022 was released a couple of weeks ago, and Revit 2022 dropped yesterday. I unfortunately spend very little time in our products, these days, so I’ll leave others to extoll their various benefits. Aside from working with the Forge platform, the product (or perhaps feature-set) I spend the most time with is Dynamo. I’m always happy to see Sol’s public release announcements on the DynamoBIM blog, both for his unique writing style and the velocity of improvements the team is making... Read more →

COVID Office Occupancy: a Dynamo mega-graph and blog series

I posted, back in May, about the work we’d been doing to explore the possibility of using the Space Analysis package for Dynamo to plan for post-COVID office layouts. Soon after that post our research relating to the pandemic shifted focus towards a longer-term plan of creating a “living lab” that would allow us not only to explore how design decisions might impact viral transmission, but to have these decisions based on data measured from a functioning ventilation system. Expect to hear more about that research in a future post. We handed over the work that had been done... Read more →

Dynamo Core 2.10

Santa (meaning Sol Amour) has left one last Dynamo release under the tree for us all to enjoy over the holidays: Dynamo Core 2.10. According to Sol’s post there have been a few updates to Node Autocomplete – which I mentioned a few weeks ago – but that we should expect many more to come. And there are other updates that are likely to be of interest in this release, too – check out Sol’s blog post but also the release notes. There are a few new nodes in this release, for instance: AnyTrue, AnyFalse and a Math.Random node... Read more →

Have you tried Node Auto Complete in Dynamo 2.9?

If so (or if not but you’re up for doing so) then the Dynamo team would like to hear from you! For some background, here’s the post on Dynamo Core 2.9 that introduces the feature. To enable the feature via Settings –> Experimental –> Enable Node Auto Complete. Then you can simple place a node (from the Library or by right-clicking on the canvas) and start to use auto-complete to find nodes to connect by Alt-clicking the input ports. Here’s me creating a small graph to create a polygon, for instance. From my cursory inspection it seems a really... Read more →

Dynamo 2.7 – Migrating MaRS to CPython3

After being teased with some graphics improvements coming in Dynamo, I was excited to find on returning from my recent holiday to find a new release of Dynamo Sandbox was available for testing. There are a number of notable features available in Dynamo 2.7, whether the ability to run CPython3 code – rather than using IronPython, which is based on Python2 – or improved graphics preview performance thanks to an upgrade to Helix. I started by just loading v2 of the MaRS graph, without changing any of the code blocks to use CPython. Straightaway I found that the graphics... Read more →

Saving data for selected generative designs from Revit 2021

In the last post we saw how the Data.Gate node can be used to send geometry to Revit 2021 when the “Create Revit Elements” button gets pressed from the Explore Outcomes UI for a Generative Design study. Phew. In this post we’re going to dig into how this node can also be used to have other “side effects” such as storing the various input parameters to a text file. For the purpose of this workflow I’ve chosen to hack the standard Three Box Massing.dyn graph (which ships with Revit 2021 as a sample for the Generative Design feature). The... Read more →

Managing data flow to and from Generative Design studies in Revit 2021

I was inspired to write this post by a chat I had with Zachary Kron, earlier in the week. I’d been noodling on how best to support a workflow where users of the Generative Design feature in Revit 2021 can select specific solutions in a study and do something with them. The specific use-case was around some functionality I’d prototyped back during the days of Project Refinery, where while exploring the results created during a generative study you could double-click individual designs – whether in the scatterplot or the design grid – which would add them to a graphical...

Don’t worry – we must have finally reached "peak Kean"

I have the sense that I’m seeing my face too much at the moment (admittedly I’m very attached to it… haha). All I can say, in my defence, is that over the last few weeks I’ve started to receive more requests to participate in virtual activities. And I’ve mostly said yes, as it’s a reasonable alternative to travelling to meet people, given the current circumstances we’re all in. In case you haven’t seen these various pieces of virtual content – and you’re actually interested – here’s a quick round-up of some current and future ones. Getting Simple When my... Read more →

An update on our post-COVID office layout explorations

For the last few weeks I’ve once again been heads-down on Generative Design-related tasks after several months working almost exclusively on Dasher. I like switching context like this but it can certainly be a little disorientating, at first. Anyway, it’s been really interesting working once again with my friends in the AEC Industry Futures team (the rockstars formerly known as The Living), and with Rhys Goldstein – the designer of the algorithms driving the Space Analysis package – on imagining a tool to help with post-COVID office layouts. Something I speculated about a little while ago, although that was... Read more →

Online lectures from ITA and IAAC

As a follow-up to the last post which talked about SimAUD and it’s going online, today I wanted to mention some other online resources that might also be of interest to people during these times. The Institute of Technology in Architecture (ITA) at ETH Zurich is one of many institutions that have moved their public lectures online and have made them available for anyone to watch. So far I’ve watched a couple of them live, the second one being by my friend and former colleague, Matt Jezyk, who is now spearheading Tesla’s efforts to streamline gigafactory design using techniques...

Attend SimAUD 2020 online next week for only $50 ($20 for students)

Next week is the annual Symposium on Simulation for Architecture and Urban Design (SimAUD, pronounced Sim-Odd). This conference was started a decade ago by my former manager Azam Khan, along with Gabriel Wainer and Ramtin Attar. I’ve only had the pleasure of attending one SimAUD event – the 2018 edition was held in the Netherlands at TUDelft – but I was hoping/planning to attend this year’s in Vienna: a paper submitted by Rhys Goldstein – with Simon Breslav , myself and Azam as co-presenters – was accepted for the conference. Here’s a quick photo from a dinner we had... Read more →

Minor updates to Warnamo and Capturefinery

I’ve made some minor tweaks to a couple of my Dynamo packages, this week. One was to make sure Capturefinery – a tool that generates screenshots and animated GIFs for Refinery optimisation runs – works with the shipping release of Generative Design for Revit 2021 (it now does, but needed to look in a new directory structure). This is available from Capturefinery 0.9.11. The other was to add a feature to Warnamo – a tool that lists the warnings and errors in your Dynamo graph – to let you export the error list to Excel. This is available from... Read more →

Dynamo 2.6

I’ve been banging pretty hard on Dynamo 2.6 – via Dynamo Sandbox – for the last few days, and I have to say I’ve been very impressed. Node renaming labels, code numbering, much improved PolyCurve performance… the combination of these various features have really helped with a project I’m working on right now (more on this next week). Congratulations to the Dynamo and Matterlab teams for this compelling update. So far it’s really making a big difference. Check out Sol’s blog post and head on over to DynamoBuilds.com to get the Sandbox build to try out! Read more →

Getting better-looking text in your Dynamo graph output

One of my pet peeves with Dynamo – as I typically use it standalone from Revit – is the quality of the text you can generate as graphics: the Dynamo Text package will generate curves (actually lots of little lines) that represent the outline of your characters, but they often look quite lame depending on your zoom level. Actually scratch that – they look lame irrespective of the zoom level. Sigh. Anyway – today I finally dug into what I needed to do to create better-looking text as output from your Dynamo graphs. My first attempt was to create... Read more →

Geometry Systems and the Refinery Primer

I mentioned last time that I was expecting to publish some posts about Autodesk University 2019 material I found particularly compelling (now that I’ve had the chance to consume some). I didn’t get to watch as many recordings as I’d have liked – for now – but I did manage to watch the rest of a class of which I only caught the first few minutes before having to run to another meeting in Las Vegas, my friend Lorenzo Villaggi’s session on Geometry Systems. There are two main pieces to generative design systems – at least in the way... Read more →
