Through the Interface

Speaking at tomorrow’s BIM Fórum Brasil about Digital Twins

I’ve been asked to talk about our work on Digital Twins (or Gêmeos Digitais) at the BIM Fórum Brasil event, on Wednesday of this week (January 26th, 2022). The event starts at 10am in Brasilia, which is 2pm in Central Europe, so the timing should work well for Asia, Europe and early birds on the east coast of North America, too. I’ll be sharing information on our older projects, as usual, but I’m also planning to showcase some of our more recent (previously unseen) projects. So there’s likely to be new information even for people who have seen me... Read more →

A video on using slicing, meshes and Python with VASA

Fancy a nice slice of VASA to finish your week? Luckily Rhys Goldstein is here with Part 4 in his video series introducing VASA features. In this episode, Rhys talks about using slicing functions with voxel models, how to iterate through voxel models using Python, as well as a number of nodes that help you work with meshes inside Dynamo (and VASA). He also covers a couple of techniques that allow you to export voxel models to Dynamo geometry, and even navigates through the shell of an exported voxel model to show you what it looks like from the...

Draping temperature data from a thermal image across the Forge viewer scene - Part 1

I work in the Research Engineering team at Autodesk, a centralised pool of software engineering talent that contributes to research projects across our various industries. Organising this way allows us to explore commonalities (and efficiencies) that would otherwise be hard to achieve. Every year or two we have an internal “Innovation Days” event, which is essentially an internal team hackathon. (Lots of other teams at Autodesk do this, of course, we’re far from being unique in that regard.) Our latest Innovation Days took place on Thursday and Friday of last week, with the theme of sustainability. I met with... Read more →

VASA 0.1.2 is now available

The first version of VASA we posted to the Dynamo package manager was numbered 0.1.0. Yesterday we posted a new version with some interesting new features, not least of which is the lack of an error when you install it (this one was very much my fault: I’d neglected to mark a couple of DLLs as not being node libraries when I posted it). Here’s a breakdown of the new features in 0.1.2, courtesy of the package’s author, Rhys Goldstein: Added VoxelModel.ToSolid, which converts a voxel model into a Dynamo solid that can be processed using standard Dynamo operations...

Using VASA via WebAssembly for pathfinding inside FormIt

As a quick recap, here are the posts we’ve seen in recent weeks on this topic: Autodesk FormIt and its JavaScript API Introductory look at FormIt and the Maze Generator plugin. Using VASA with FormIt via Dynamo – Part 1 How VASA can be used within Dynamo for FormIt to solve mazes (etc.) in 3D. Using VASA with FormIt via Dynamo – Part 2 Applying the same principle with urban scenes imported by the 3D Context Creator plugin. In today’s post we look at the fact that VASA can also be used directly from a FormIt JavaScript plugin –... Read more →

An interview and an anniversary

Recently Mayur Mistry from Engineering ArchiTECHure asked me to join him for a YouTube livestream. Mayur often holds his interviews over the weekend, but he very kindly accommodated my schedule and held the session during the week. So while it was “live”, it wasn’t at the usual time for Mayur’s subscribers and the discussion remained very much between the two of us. I’ve seen some really good sessions on his channel – several of his guests have prepared extensive material to show – so my apologies if you’re expecting something more formal: we just chatted for an hour. Many... Read more →

Using VASA with FormIt via Dynamo – Part 2

In the last post we looked at using VASA from within Dynamo for FormIt to solve mazes generated by a cool plugin created by Brett from the FormIt team. The Dynamo graph we saw used VASA in “3D mode” – where the voxel height is higher than 1 – but that came with the added need to create a floor for the maze (something that isn’t too hard, as we know the exact dimensions and location of the maze). In today’s post we’re looking at how VASA might be used to perform pathfinding operations at the urban scale, taking... Read more →

Using VASA with FormIt via Dynamo – Part 1

In this recent post we looked at FormIt’s JavaScript API and learned how Brett Garrison was able to use it to develop a Maze Generator plugin. In this post we look at one way to find solutions for the mazes generated by this plugin using VASA from Dynamo. When I first started looking into VASA with FormIt, Rhys Goldstein sent across a Dynamo graph he’d used to grab contextual building geometry from FormIt – to create a voxel model of the space – and then send the pathfinding results back afterwards. I’ve adapted this graph to work with the... Read more →

Want to see Dasher inside Tandem? Tell us what you need.

The Autodesk Tandem team has just launched their Customer Research Program. This is the perfect way to engage with the Tandem team and let them know what features you might need from your future digital twin infrastructure. In particular, if you’re interested in seeing features from Project Dasher show up inside Tandem – via what I referred to in a recent post as “Dasher inside Tandem” – then this is your chance to be heard. Related to this topic, I came across a funny meme recently on Twitter. I couldn’t find it again, so here’s my attempt at reproducing... Read more →

A video on pathfinding with VASA

Rhys Goldstein has published the second part of his informative video series on using the VASA (Voxel-based Architectural Space Analysis) package with Dynamo. The first part was an overall introduction to the package while this part dives into pathfinding, taking a close look at samples that show how it might be used in both 2D and 3D. While the overall video is really interesting – some of you might find it a bit long at 43 minutes but it’s quite watchable at 2X and is packed full of useful information – one of the sections that stood out for...

Autodesk FormIt and its JavaScript API

A few weeks ago I started taking a closer look at Autodesk FormIt, mainly with a view to understanding how it might integrate with VASA. FormIt is a multi-platform (which I believe in this case means Windows, iOS and web) conceptual design and analysis tool. I haven’t really followed the development of FormIt, over the years, so if you’re interested in learning more about that then I suggested heading over to the product team’s blog. If you want to get started with using FormIt, then this Primer seems helpful. Two things in particular had me intrigued about FormIt: its... Read more →

A video introduction to VASA

Rhys Goldstein, the researcher behind our 2D and 3D Space Analysis toolkits, has recorded a great video introduction to VASA (an acronym for Voxel-based Architectural Space Analysis). It steps through how to install the VASA package inside Dynamo and then create a simple voxelisation of Dynamo geometry. Rhys also shows how to load and run the samples provided with the package, and takes some time to step through – and then dissect – the main overview sample. Here it is: If you don’t have time to spend 23 minutes watching a video, it should be quite watchable at higher... Read more →

Forge and digital twins at Autodesk University 2021

I’ve finally found the time to view the main information from the recent Autodesk University event, and thought it worth highlighting what I consider to be some of the “big ticket” items, especially from my own – somewhat Forge- and digital twin-centric – perspective. First-up, Forge was everywhere in the keynotes. If it wasn’t previously clear that Autodesk is serious about becoming a platform company, it should be from the messaging at this AU. On a side note, there are a number of internal organisational changes that have happened/are happening at Autodesk to accelerate this shift, so I’m currently... Read more →

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 →

Bundle optimization in Project Dasher

I mentioned recently that I’ve been working on updating Project Dasher’s use of 3rd party components, and that I had some learnings to share. We started the Forge-based version of Dasher in 2016, and (much to my shame) some of the components had stayed at more-or-less the version available at that time, largely due to the migration effort needed to deal with breaking changes. Biting the bullet to upgrade them was painful but necessary, and right now I (and Dasher) feel nicely refreshed. Last time I mentioned there were two big outstanding dependencies that still required attention: Bootstrap and... Read more →

Build your first Digital Twin at the upcoming Forge Hackathon

Other that my regular foolings-around with ancient tech, I feel like I’ve been neglecting this blog in recent weeks. That’s all about to change, though, as we enter the busy period leading up to Autodesk University 2021. For one I have some interesting learnings I thought I’d share from some of the foundational work I’ve been doing on Dasher’s codebase, but there are also some interesting updates for people performing analyses of 2D (and 3D!) spaces. Fun stuff! First though, it’s worth reminding people of the Forge Hackathon that’s around the corner. It starts in just a couple of... Read more →

A minor makeover – and a lot of core work – for Dasher

Over the last week I’ve been heads-down on core Dasher work, but with very little visible result. Here’s why. Early last week I received an email telling me that it was time to dig into Dasher’s use of 3rd party components and make sure there weren’t any security issues. (This isn’t something unusual – all our products go through this, and many of our research projects, too.) As anyone working on web development projects will know, it’s important to go through from time to time to reduce the technical debt that accumulates due to the use of old libraries... Read more →

A new face in the Autodesk Tandem team

My friend and colleague Hali Larsen has joined the Autodesk Tandem team as a Product Manager focused on connected workflows and sustainability. This is huge news, for lots of reasons: for several years Hali played an absolutely instrumental role in Project Dasher – in many ways she was our de facto PM, but also worked through many gnarly issues related to bespoke configuration for various Dasher pilot projects. Hali has a wealth of experience working with customers in this space, and also knows where most of Dasher’s skeletons are buried, so she is the right person to take on... Read more →

Previewing and viewing PDFs inside Dasher

A couple of days ago we were looking for the datasheets for the various sensors installed in the MX3D bridge: as you’ve probably already read, there are nearly a hundred sensors in and on the bridge, although of only about eight different model types. My colleague Josh Cameron said, in passing, “it would be really handy to have these datasheets integrated into Dasher!”. As usual, this sent me down a rather fun rabbit-hole for a day or so, to see how we might reasonably integrate these PDFs into Dasher. Firstly it’s worth pointing out that these days the Forge...
