AU 2015 handout: Virtual Reality Viewing of 3D Models Using Autodesk's View and Data API

I’ve been heads-down wrapping up my AU content, so I thought I’d publish at least some of it here. Here’s the handout for my “AU kick-off” class which is at 8am on the first day of the conference – the morning after the ADN party – so despite the fact the class is currently full, we’ll see if that turns out to be the case. ;-) VR comes of age Presenting 2D images that allow the brain to reconstruct 3D has its roots in the early stereoscopes invented in the late 1830s. These were eventually democratized by Sawyers and... Read more →

AutoCAD I/O v2

The AutoCAD I/O team has deployed version 2 of their API. For specific information on what’s new, check this page. As I’ll be talking about AutoCAD I/O at AU 2015, I thought it important to get to grips with the new version and understand how it differs from v1. I went ahead and updated Jigsawify.com to make use of the new API, so I’ll add my own commentary below on the changes that have been introduced. As a reminder, the full source code for Jigsawify.com is available on GitHub. To check out the specific migration changes, see this comparison... Read more →

Autodesk DevDays 2015

Members of the Autodesk Developer Network have started receiving information on how to register for the upcoming series of DevDays being held around the world. Thanks largely to the positive experience of running Cloud Accelerators in different locations, the ADN team has shifted their thinking for this year’s tour: rather than visiting 15+ cities around the world, the team has reduced the number of locations to a few per geography but increased the amount of time being spent in each. 3-4 day Accelerators will be held in a number of cities adjacent to the more traditional DevDay events. This... Read more →

At the Cloud Accelerator in Prague

We’re about halfway through the first Cloud Accelerator Extension being held in the incredible city of Prague. The entire European ADN team is in town – so a great chance to catch up with old friends such as Jeremy, Adam, Philippe, Cyrille and Peter – along with cloud-focused developers from Norway, Denmark, Belgium, the Netherlands, the UK, Germany, Romania, Italy, Greece, Israel and (of course) the Czech Republic. So definitely making new friends, too. :-) I’m mainly here to help developers working with AutoCAD I/O – gathering feedback for the development team, in the process – and it’s really... Read more →

I <3 DWG Meetup in Prague

I’ll be in Prague – with Adam Nagy from the ADN team – on Tuesday of next week (from 6 to 9pm on September 8, 2015) to talk to people about Autodesk’s horizontal PaaS offerings, notably the AutoCAD I/O and View & Data web services. If you happen to be in the area and are interested in attending, please sign up and come on by the Autodesk Prague office on Tuesday evening! From my side I’m going to talk about the implementation details relating to the use of Autodesk web services in Jigsawify and Vrok-It. It should be a... Read more →

Let’s get physical: laser cutting the output from Jigsawify.com

After building a web-site to create files that help make laser-cuttable jigsaws, it made sense to actually go ahead and cut some. In the flesh, so to speak. My initial findings weren’t good: I’d assumed that I could output 2D solids from AutoCAD – each representing a pixel to be engraved on the jigsaw – and that the laser cutting software (in our case LaserCut 5.3) would at least see the boundaries. But nothing at all loaded – apart from the cutting geometry for the pieces, of course. In fairness, the question has come up a few times as... Read more →

Passing large amounts of data to an AutoCAD I/O activity

I mentioned recently that I’d hit a limitation with the amount of data that could be passed as embedded JSON data to an AutoCAD I/O Activity, and so decided to rearchitect my site to post the data at a URL and have the Activity download and use the data from there. The system worked well until a security flaw was fixed by the AutoCAD I/O team, earlier this week: it turns out the approach of manually downloading the additional payload from the Activity itself wasn’t supposed to work. And now, sure enough, it doesn’t. :-) This video does a... Read more →

Jigsawify.com: Creating custom jigsaw puzzles using AutoCAD I/O

After the last post, where we looked at the first couple of architecture iterations for Jigsawify.com, it’s time to summarise (and perhaps even wrap-up) this series… Here are the posts so far: Puzzling over laser cutters AutoCAD I/O and custom applications Finishing up our laser-cut jigsaw project Running custom .NET code in the cloud using AutoCAD I/O – Part 1 Running custom .NET code in the cloud using AutoCAD I/O – Part 2 Running custom .NET code in the cloud using AutoCAD I/O – Part 3 Running custom .NET code in the cloud using AutoCAD I/O – Part 4...

Architecting my first AutoCAD I/O application

As mentioned in this recent post, I’ve been working on my AutoCAD I/O-driven web-site on and off for the last few weeks. Lately I’ve had to think beyond certain assumptions I’d made about its architecture, and I thought it worth sharing those thoughts here. The intention of the site is that you upload an image and then see some edge detection get performed on it, generating an engraving layer for a custom jigsaw puzzle. AutoCAD I/O gets used to generate a drawing that can drive a laser cutter, creating your 100% unique jigsaw puzzle. Basically making the world a... Read more →

Visualizing the AutoCAD I/O API

I’ve been working with AutoCAD I/O quite heavily over the last week or two – mainly spending time fleshing out my Jigsawify web application well in advance of AU2015 – and came across this helpful trick for visualizing an OData-based REST API graphically: you can copy and paste the XML schema for the AutoCAD I/O API into a file and then load it into the handy XOData tool. Here’s what was generated (after a little editing from my side for layout): I’m making pretty good progress using AutoCAD I/O from Node.js – which is interesting as I can now... Read more →

The next Autodesk Cloud Accelerator is in… Prague!

After the first two successful Cloud Accelerators held in San Francisco, it’s time to go international. The next one, labeled a Cloud Accelerator Extension, is being held in the beautiful Czech city of Prague from September 13-18, 2015. This is a great opportunity to kick-start your development using Autodesk’s PaaS infrastructure. Members of the ADN and Engineering teams – me included – will be on-hand to help you work through any development issues you hit while creating or honing your Autodesk Cloud API-integrated application. So come join me in Prague for a fun week of cloud-oriented development. All you... Read more →

Running custom .NET code in the cloud using AutoCAD I/O – Part 2

As promised yesterday, this post deals with modifying your CRX module to make it work with AutoCAD I/O. A quick reminder on what writing a CRX app means for .NET developers: we’re still creating a .DLL (unlike ObjectARX developers, whose CRX modules have the .crx extension), but it can only reference AcDbMgd.dll and AcCoreMgd.dll (not AcMgd.dll). Importantly the module must be loadable – and testable – in the Core Console. The basic C# code we’re going to extend is from this previous post. The real change that’s required for commands to work in AutoCAD I/O is how they get... Read more →

A fun, collaborative VR tool: can you Vrok-it?

It’s live! Our entry for the recent VR Hackathon in San Francisco has received a significant amount of spit and polish (OK, perhaps not the best mental image) over the last couple of weeks and is now ready for prime time (i.e. Beta testing ;-). Check it out at http://vrok.it! It should work well with Chrome, Firefox or Safari, although for best results I’d stick with Chrome on mobile devices. The term “vrok” is one I came up with on the trip back from San Francisco… it’s a combination of an invented acronym – Virtual Reality Online Collaboration –... Read more →

Our collaborative VR demo from the recent Hackathon

I wanted to post on a more in-depth topic, today, but I’ve been heads-down working on our project from the recent VR Hackathon, getting ready to push it live. We’ve made really good progress over the last few days, especially considering it’s only a part-time project for Lars, Oleg and myself. We’ve implemented per-session support and a number of other important features (Lars has also spent some serious time re-factoring the code – it’s certainly more elegant than what I’d usually crank out ;-). The code is all here, in case. Here’s a quick audio-less demo, to give you... Read more →

Cooling down after the SF VR Hackathon

The 2nd VR Hackathon, which took place in San Francisco over the weekend, was an absolute blast. It was held at Galvanize, a co-working space about a 15-minute walk from our 1 Market Street office. The venue was great: it had plenty of space but also with a fair amount of natural light (very important for those of us getting over our jetlag). There were fewer people at this second event – inevitably, as it happened over the Memorial Day weekend – but there was nonetheless a great energy in the room. At the core of our team –...

Viewing 50+ design software formats from a web-page

This is very cool. As Stephen Preston has reported, over on the Cloud & Mobile DevBlog, the A360 team has delivered a widget that can be embedded in web-pages and views design files – including DWG files saved from AutoCAD, of course – that are dragged & dropped onto it. Basically allowing you to view them as you would in A360, but inside any web-page. Instructions are available at 360.autodesk.com/viewer/widget, although – as Stephen notes – be sure to call adskViewerWidget.Init() with a capital “I”. There are two ways to render the widget. You can either render just the... Read more →

VRing in SF

I’m on the train to Zurich airport, where I’ll hop on the direct flight to San Francisco. This evening I’m staying in San Jose, as tomorrow I’ll be visiting the SVVR 2015 expo hall to do some research on the latest virtual reality technologies in advance of the coming weekend’s VR Hackathon (following on from the one in October). This Hackathon is set to be really fun: while last time I ended up mostly talking with people about Autodesk and the View & Data API, demoing the Google Cardboard prototype I put together – which was also fun, especially...

AutoCAD I/O and custom applications

The title of this post is probably a bit misleading: I’m not actually going to show how this works, today, but I do intend to plot a path for addressing this topic over the coming weeks. I was spurred on by a tweet I received a couple of hours ago: @keanw Dear kean, I've been looking into AutoCAD I/O and it looks like it may only execute "scripts"; so no .NET API calls or LISP? — Cyborg (@CyborgEvilHam) May 13, 2015 The short answer to this is “yes, it’s absolutely possible!”. But readers of this blog are clearly interested... Read more →

AU2015 Call for Proposals opens next week

The countdown for Autodesk University 2015 starts with the Call for Proposals opening on April 22nd. It will remain open until May 26th. I have a few ideas for possible topics to present at this year’s event… Virtual Reality using Autodesk’s View & Data API Developing JavaScript applications for AutoCAD using TypeScript Processing drawings in the cloud using AutoCAD I/O They all seem to be valid topics, but we’ll see if I can find the energy and motivation to submit all three. If you have an opinion on what you’d like to hear me talk about – even if... Read more →

Autodesk Cloud Accelerator v2 | Updated developer portal

Thanks for all the interactions, yesterday. April 1st is really one of my favourite days of the year: there’s lightheartedness and creative energy everywhere you look. But all good things come to an end – even if the years seem to tick by increasingly quickly – so it’s time for more serious matters. Today’s post shares a couple of updates related to Autodesk’s burgeoning PaaS layer… Firstly, the inaugural Autodesk Cloud Accelerator turned out to be wildly successful: both for the external people who attended – there were 12 proposals selected from a pool of 50, with developers focused...
