Persisting identifiers for objects in the Forge viewer

In Dasher we have some interesting functionality to isolate parts of the building by level. This is increasingly something you can do via “out of the box” Forge viewer functionality, but we’ve found a couple of reasons to go beyond that basic capability: Not all elements or objects are assigned to the correct level. Some elements – such as those belonging to the building facade or perhaps internal pipes – transcend levels, and so don’t behave well. It’s of course possible to split elements/objects that belong to the second category, but we tend to take the approach of allowing... Read more →

More data from the NEST building now available in Project Dasher

I’ve been heads-down this week on a couple of tasks related to Dasher: the first relates to working on the integration of a new timeline control. I’m hoping this will be ready for people to try in the coming weeks, but we’re not quite there yet. The second relates to bringing more data into our time-series back-end from the NEST building: I noticed last week that we were missing data from October of last year onwards. It turns out we had a credentials problem – we have a “conduit” that regularly federates the NEST data into our back-end, but... Read more →

Migrating custom Forge viewer shaders to WebGL 2 – Part 2

A few posts ago I mentioned some work was needed to migrate our Dasher 360 shaders to the latest version of the Forge viewer (or the one after it). This work is now complete, so I can share a few thoughts and comments on what was needed to make this happen. Before doing that, though, I need to thank Elias Cohenca for his invaluable help during this process: I can honestly say that without his help the migration would either not have happened or would remain a work in progress. Thanks, Elias! Firstly, it’s important to note that even... Read more →

Visiting NEST with Kingspan

On Wednesday I was back at the NEST building on Empa’s Dübendorf campus. I’ve posted about NEST lots of times over the last few years, but these are the main two tours in case you want to track its evolution. I was there to meet Brian Glancy – visiting from Kingspan in Ireland – and Reto Largo from NEST. NEST and Kingspan are two of the main ongoing pilots of Dasher, so it was great to get everyone in the same place to discuss possibilities. Reto started the tour in the media room in NEST, with it’s 16-screen media... Read more →

Migrating custom Forge viewer shaders to WebGL 2 – Part 1

An interesting thing happened when I tried Dasher 360 with the latest production version of the Forge viewer: no sensor dots appeared. As Dasher without sensors is a glorified 3D viewer, this was a bit of a problem. Digging into things a little, I worked out that our custom WebGL shader wasn’t working properly in this latest version. At this point I reached out to my friend Elias Cohenca in Tel Aviv for a quick sanity check: he confirmed that this latest version of the Forge viewer is now defaulting to WebGL 2.0. This was confirmed in the Forge... Read more →

Swissbau 2020

Bright and early, yesterday morning, I hopped on a train (well, a couple of trains) to get across to Basel for this year’s Swissbau, the bienniel construction-related trade show held in Switzerland, and apparently one of the largest in Europe. I’d never been before, but thanks to social media I’d compiled a list of people to see there, and had even coordinated to meet up with my friend and fellow blogger, Jeremy Tammik. There was quite a bit going on at Swissbau, even outside the exhibition hall. At one point I saw some people performing while suspended from a... Read more →

Visually clustering the contents of models in the Forge viewer

Some of you may already have seen Augusto’s tweet showing the “Visual Clusters" Forge viewer extension that has been developed by the BIM 360 Design team. It really is super-cool: the extension takes the content of the model loaded in the Forge viewer and clusters it spatially based on the value of the various items’ category property. The extension was first published in v7.6 of the Forge viewer, so it’s been around a little while. If you don’t have a Forge viewer application to test it out with, fear not! Petr Broz has added the capability to load extensions... Read more →

Additively Manufacturing Music using the Printesizer

I mentioned in the last post that I had a fun topic to share to help get the new decade started. Well, here it is! I’ve been collaborating with Elias Cohenca from our Tel Aviv office on and off over the last few years: Elias managed to port the THREE.MeshLine JavaScript library to work with THREE.js r71, making it compatible with the current releases of the Forge viewer. We’ve made heavy use of this library in Dasher 360 to represent skeletons and streamlines, for instance. I’ve also been mentoring Elias, something I mentioned in this post from the middle...

My AU 2019 classes

The Autodesk University elves have been working day and night over the last few weeks to prepare 674 AU class recordings for posting to web. Some of my classes were livestreamed, this year, so I have already posted recordings for these. This post is just me gathering the various recordings together in a single post. Before that, though, I did promise a festive photo for each of the coming posts. Here’s one I took this morning, when we woke to find that St Nicholas had passed by the house. The feast of St Nicholas – which is celebrated throughout... Read more →

Reliving AU in Amsterdam

As the festive season is upon us, I’ve decided to start each post with a seasonal photo. Here’s me with a reindeer/dog (reindog?) in the lobby of the hotel we stayed at in Hoofddorp. As mentioned in the last post, Sander Lijbers made the most of my vague suggestion to meet with a customer or two during my visit to the Netherlands by inviting many of the accounts he manages to a one-day event in our Amsterdam office. Everyone accepted – with some even flying in from the UK – so we had a really good, engaged group! Sander... Read more →

Digitalisation workshop at TU Delft

After not being good for very much last week – while recovering from AU in Las Vegas – I headed back across to the Netherlands on Monday afternoon. In Geneva airport there was a large stuffed reindeer just sitting there. A huge thanks to Ben Rand for pointing out the obvious: that Rudolph is probably a big fan of Project Dasher! :-) I took the train from Schipol down to Delft, which was feeling very festive. I love Dutch train stations and the connectivity between multi- and two-wheeled transport. I had a very nice room in a hotel close... Read more →

Wrapping up Autodesk University 2019

Wednesday and Thursday were my busy days at this year’s Autodesk University in Las Vegas. After a breakfast meeting with a colleague from Toronto, I had my first class of AU2019 to deliver. It was a live-streamed class that was focused on advanced visualization (primarily of IoT data) using the Forge viewer. Somewhat unfortunately the class was scheduled at the same time as the AEC mainstage (more on this later), but that basically just meant that the room wasn’t completely full and that most of the attendees were Forge-focused. As it was live-streamed the class recording is already available:... Read more →

An updated model of the NEST building, now live on Dasher 360

A few days ago our friends at BIM Facility AG sent through a new version of the Revit model for the iconic NEST building. This version is much more complete: it has the award-winning Urban Mining and Recycling Unit modelled, as well as having a significant amount of additional detail (furniture, etc.) elsewhere in the building. The DFAB House has also received a makeover, getting more realistic materials, plus the ability to see into its ground floor and robotically-printed supporting wall. Considering all the hard work the BIM Facility team has put into making this version so much better,... Read more →

Not coming to Las Vegas? Watch two of my AU2019 sessions from the comfort of your armchair

Or at your desk, or from the train. Just please don’t watch them while driving. Anyway, the point is that this year two of the three sessions I’m presenting at Autodesk University 2019 are part of the event’s livestream schedule. The first is on Wednesday at 10:30am Pacific: The second is on Thursday at 3pm Pacific (I have a 15-minute segment at some point during the hour timeslot): I’m not sure what’s happening with my third class – which is focused on Project Rediscover – but if that doesn’t end up getting recorded I’ll make sure equivalent material is...

Counting down the days to AU2019

I’m currently putting the finishing touches on my material for Autodesk University 2019. To encourage a few last-minute sign-ups, here are a few teaser GIFs from my classes. The first is from the class on Project Rediscover (which is apparently now full at 109 sign-ups, so in quite a small room). I used Capturefinery to create a GIF of quite a large Refinery study, but this time highlighting the congestion in a more 3D context. The second is from the class on Project Dasher – and using Forge for advanced data visualization – which still has 36 spaces in... Read more →

BILT and the Highlands

After the pre-BILT Hackathon on Wednesday, there were still three full days of the main conference to be experienced in the beautiful city of Edinburgh. My family was with me – at the start of our 2-week Scottish adventure – so I wasn’t planning (or able) to spend the full 3 days at the conference. I did make it along to the opening keynote, however, which was largely run by Marcus Fich, who introduced two Danish psychologists who talked about (among other things) our response to stressful situations. It was a very different and interesting session. After that I... Read more →

The first BIM 360 community event in Switzerland

Yesterday I was back at the NEST building in Dübendorf for Autodesk’s first BIM 360 community event in Switzerland. It was nice to be back there, even if just to see the progress being made on the construction of the HiLo roof. Here’s the view from the ground: I also went up to take a few snaps from the roof. You can clearly see the knitted cabling that will provide support for the structure. There were a few people working on the structure, too. (I took my snaps from an open doorway as I didn’t want to disturb them.)... Read more →

A major update to Dasher 360; now showing the NEST building

Today’s a big day: Dasher360.com has been updated to let you browse the model and data coming from Empa’s amazing NEST building in Zürich, Switzerland. Head on over and give it a try! Here’s a quick video introducing the new Dasher 360 (you can also access this from the main Dasher 360 page): Expect the model to improve, over time: we want to include a few additional units – such as the Urban Mining & Recycling unit – as well as increase the number of sensors and remove a few visual artifacts. But in all honesty it’s already super-cool,... 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 →

NEST and ETH Zurich

At the beginning of this week I headed back across to the fine city of Zürich for a couple of days. My first port of call on Monday morning was to the NEST building on Empa’s Dübendorf campus. (I’ve talked about NEST many times in the past, as we have an ongoing project to host its digital twin using Dasher 360.) Arriving at the building it was exciting to see the building covered with scaffolding, as the work has started to build the HiLo roof. Here’s the breakdown of NEST’s units by floor. HiLo is accessible via the 3rd... Read more →
