Through the Interface

Data resolutions in Project Dasher

When we started developing Dasher in late 2009 – back then it had a desktop client – one of the main drivers was around providing an interface to explore IoT data (at the time measuring building performance) responsively in a 3D context. To do this we knew that we needed some way to summarize the raw sensor data at different levels of detail: there was no way we could wait around for the client to query years of sensor data in order to visualize a high-level summary, for instance. In our time-series back-end the team developed a mechanism we... Read more →

The first online AEC Hackathon

Since starting up back in 2013, the AEC Hackathon team has organised 43 in-person events in various cities around the world. This year being “special”, they’ve taken the plunge and set up a couple of online events, the first was held from July 6th-26th while the second will be held from October 9th-25th. I was on holiday for the first two weeks of the July event, so could only really participate by presenting a topic during the final week. Here are a couple of screenshots of me – taken from the session recording, which should still be available on-demand... Read more →

Autodesk Research is hiring experienced software developers and designers!

These days I belong to the Research Engineering team at Autodesk, headed by Tony Ruto. (Tony joined Autodesk with the acquisition of Within Technologies, back at the end of 2014, where he was CTO.) Tony’s team is a shared resource for the various “Core Science” and “Industry Futures” teams within Autodesk Research: we help develop prototypes and platform capabilities that are used elsewhere in the organisation, and also have members of our team embedded within these other teams. The team is growing, which is quite exciting: there are a number of open positions that I’d encourage you to share... Read more →

AEC Hackathon, CanBIM recordings & AU class voting

This post is a bit of a grab-bag of various event-related topics. The first one (chronologically, if not in terms of the title above) is the availability of session recordings from the recent CanBIM event: “The Future of Work: Designing Resiliency and Building Work Safety Post-COVID”. My own session was entitled “Using Generative Design and Digital Twins to Improve Occupant Well Being”. As it was the first session of the day – with a new web streaming platform – there were a few teething issues for the sponsor’s introduction (and the session auto-closed a little too promptly, which meant...

Give Dasher sharing a try

While I announced the sharing feature – and its corresponding API – some time ago, I still had some work to do before it could go live on the Dasher site: largely around supporting timezones properly when specifying time ranges for data display, but there were some other minor tweaks needed, too. Anyway, the feature is ready enough for people to kick the tyres on it, at least. Here’s a link which will launch the public Dasher demo for you, taking you straight into a “surface shading” view for C02 values on the 1st floor, bringing up the graph... Read more →

Visual clustering is now live in Dasher

I have a quick update to share on Dasher, today: I’ve just pushed live a version to the main Dasher site that enables a core Forge viewer extension to perform visual clustering of model contents. I talked about this back at the beginning of the year, but there was a core change needed to the Forge viewer to make it work for Dasher: specific details are in the blog post I just linked to, but it relates to the fact we rely on the Navisworks format for our models, and these have a different property structure when loaded through...

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 →

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...

Virtual Forge Accelerators – coming to an office (very) near you

For two of the last three weeks I’ve been lurking in virtual Forge Accelerators: as I mentioned last time, the Forge team has pivoted to virtual events after this year’s Accelerator in Sydney was forced online due to a COVID-related office closure. (Incidentally I need to get used to the team’s new name: they recently switched from Forge Partner Development to Developer Advocacy and Support. FPD is no more, the future is DAS!) The DAS team has since gone “all in” on these events, holding two during the month of April. The first one was codenamed Metropolis and ran... Read more →

Sharing from Dasher

Last week I talked about an API that we’ve added to Dasher, allowing it to be controlled via URL parameters. I expect this to be useful when integrating Dasher into other systems – as you can control the initial view of data, such as for a particular sensor during a specific time period – but I also expect it to be helpful for people to collaborate. It’s with this in mind that over the long Easter weekend I started building a “sharing” feature into Dasher. You can think of it as a URL builder, much in the way that... Read more →

Automating operations inside Dasher

In the last post I neglected to remind people of Kiosk Mode, a great way to see some of Dasher’s features. Simply click on the filmstrip button at the bottom of Dasher’s vertical toolbar and move the cursor off to the side (this just stops the button from staying highlighted when the cursor gets hidden). Then just sit back and see how Dasher works. Here are some posts talking about how this works. Kiosk Mode knows about various Dasher extensions and can automate their usage. There’s a fair amount of complexity in the mechanism, but it works well enough.... Read more →

Come and try the latest Dasher – now with a new timeline!

After many months of effort, we now have an updated version of Project Dasher available on dasher360.com. (The project is still very much active research, so for now you’re able to try it out with the model of the NEST building, accessible via the Demo button on the main page.) The major feature of this update is the new timeline, which was designed by Autodesk Research and developed by our partner CCTech. This component has been under development for over a year, so it’s really exciting to finally get it into people’s hands. Beyond that, you should really give... Read more →

A significant update to Dasher is on the way

For the last week or so I’ve been busy making sure Dasher works well with multiple themes. You can see the progress across these posts. I’m not quite ready for a full unveiling, but it should go live at some point in the next week, give or take. In the meantime, here are some screenshots of the main page (you’ll be able to select the theme either as you enter Dasher via the front page or from within the application’s settings UI, which is integrated into the Forge viewer’s). One of the big-ticket items in this coming release will... Read more →

Changing HIG themes at runtime in a Forge application

Despite the unfolding horror of the situation with Covid-19 – and stuff is really starting to hit the fan, here in Switzerland, with schools and non-essential commerces being closed and rumours of an enforced sequestration being considered – I’m at least getting some quality time to work on Dasher. Last week we saw how it was possible to support both dark and light themes from the Autodesk HIG in a Forge viewer application. I mentioned both times my desire to allow Dasher’s theme to be selected by the user at runtime. After searching fruitlessly on the internet for some... Read more →

Using the HIG to implement a light mode in a Forge application

Last time we saw how it’s possible to use Autodesk’s HIG to add different visual themes to a Forge viewer application. When I first started down this path, I thought I’d probably just stop at implementing another dark theme inside Dasher: I suspected it would be a lot of work to implement a light theme. It turns out I was wrong: towards the end of last year I’d spent a few days rationalising our use of styles inside Dasher, by eradicating every use of “hardcoded” colours inside CSS styles and have them stored in SCSS variables. It felt like... Read more →

Supporting multiple visual themes in a Forge application using the Autodesk Human Interface Guidelines

I mentioned in the last post that I’ve been working on integrating a new timeline component into Dasher. By default the component supports a different visual theme than the one we’ve been using in Dasher: in order to make the look & feel consistent, I had to include Autodesk’s HIG toolkit in the Dasher project. HIG stands for Human Interface Guidelines, and it’s Autodesk’s effort to increase visual consistency across our products (especially those that are web-based). And the best thing is, it’s open source and available for anyone to integrate in their projects via npm or yarn. And... Read more →

Knowing when operations are complete in the Forge viewer

We have a feature in Dasher called “kiosk mode”. It basically takes control of the browser to run a sequence of operations that show people how Dasher works. I published a series of posts a couple of years ago that explain a bit about how we implemented it. One of the issues in kiosk mode is knowing when Forge viewer operations – such as view transitions or state restorations – are complete. Until recently the code just checked the viewer’s progressbar property, to see whether its value was close to 100 or not. This wasn’t ever a very good... Read more →

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 →
