Controlling robots from inside AutoCAD – Part 3

After seeing how we can use Cylon.js to control Sphero’s Ollie and BB-8 robots from a browser, and then using the same mechanism from inside a custom AutoCAD command, today we’re going to drive these cute little bots based on AutoCAD geometry. The idea is that we’ll decompose regular curves – whether lines, arcs, polylines or splines – and use the “segments” as movement instructions for our robots. The approach is simple enough: we’ll iterate along the length of each selected curve and generate a set of instructions – really just a set of angles – for the associated... Read more →

Controlling robots from inside AutoCAD – Part 2

After looking at how to control robots using Cylon.js in the last post, in this post we’re going to get that working inside AutoCAD. For now with just a command that allows us to move the robots – in a future post we’ll analyse geometry and use that to specify the movements. The “controller” code we saw in the last post needed a little updating for use in this way. I went ahead and stripped out the keyboard-related code – as we’re using behind a web-service – and added the capability to control individual robots. We want to be... Read more →

Controlling robots from inside AutoCAD – Part 1

Happy New Year! I hope that those of you who celebrate at this time of year, were able to take a nice, relaxing break. I certainly did. :-) Anyway, it’s now time for me to ease back into work. But rather than it being an abrupt transition, I’ve decided to take a look at a pet project that I thought would be pretty fun: controlling robots from inside AutoCAD. The thinking is to outline some possibilities for moving virtual robots inside a floorplan drawing and having their real-world, physical counterparts move as instructed. Perhaps along a specific path, perhaps... Read more →

AU 2015 handout: Integrating .NET Code with AutoCAD I/O to Add Design Intelligence to Your Website

With the clock ticking before next week’s AU 2015, here’s the second of my class handouts (here’s a link to the first). For those of you lucky enough to be heading to this year’s event, see you in Vegas! Introduction During the course of this session, we’re going to look at the steps required to implement a web-site for turning pictures into jigsaw puzzles. We’re not going to go quite as far as creating the puzzles, themselves, but rather the DWG or DWF files that can be used to drive a laser cutter to do the work. The premise... Read more →

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 →

Mapping Zork inside AutoCAD – Part 2

In the last post we saw how we could integrate an HTML and JavaScript palette hosting Cytoscape.js into AutoCAD to map progress made in a text adventure. In today’s post we take the additional step of converting the graph data into AutoCAD geometry. To be clear, there’s a bit more to this post than having fun mapping old-school interactive fiction inside AutoCAD: I can think of lots of scenarios where you might want to use a comparable tool to build a graph of data and lay it out manually before bringing the graph into AutoCAD as native geometry. But... Read more →

Mapping Zork inside AutoCAD – Part 1

I mostly despise jetlag but once in a while manage to harness it for something positive. I remember some great trips to Asia, waking up at strange times to experience the dawn, walking the streets and seeing everyday life starting up around me. These days I typically find jetlag to be a bit of a curse, but this weekend I ended up using it to tackle a fun challenge: generating maps for Z-machine games such as Zork inside AutoCAD. Something I mentioned in a recent blog post but was reminded of last Thursday while catching up with Christer Janson... 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 →

Jigsawify.com goes mobile-friendly

After going down the path of making this blog responsive, it made sense to do the same for Jigsawify.com: I think it’s a really nice illustration of the potential for AutoCAD I/O to use the web-site from your mobile phone to generate a DWG in the cloud. The site itself was functional enough on mobile: the issue related more to making the UI usable without having to zoom in and out all the time both to see the results and then use the various UI elements. The “responsive” technology underpinning the Typepad template I used for this blog is... 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 →

Autodesk Technical Summit 2015

Last week I was in Singapore for our annual, internal, two-day technical summit. Upwards of 500 members of Autodesk’s various engineering and technical teams gathered together at the iconic Marina Bay Sands for the event. The hotel was pretty amazing. Having been told my room number (4619), I first exited the elevator at the 4th floor. It’s only then that I realised the rooms on each floor were numbered in double digits, and so my room was on the 46th! While I didn’t end up making much use of the hotel’s facilities – aside from the conference centre, of... 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 →

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 –...

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 →

Autodesk University 2015 class proposals

A reminder that proposals are open for AU2015 until May 26th. I’ve just submitted two, myself. Of the three topics I had in mind – relating to VR, AutoCAD I/O and TypeScript – I decided to submit proposals on the first two: I’ll do my best to use TypeScript for one or both of the other two (assuming they get accepted) which will at least give people some exposure to how the technology works. And give some good fodder for blog posts, of course. Here are the abstracts I submitted: Virtual Reality viewing of 3D models using Autodesk's View... Read more →

Extracting help IDs for AutoCAD’s UI Finder

In the last post we looked at some simple JavaScript code to automate AutoCAD’s UI Finder, locating a sequence of commands in the ribbon. In this post we’re going to look at how to generate a more extensive list directly from AutoCAD’s documentation. The first step I took was to download and install the offline help for AutoCAD 2016. This gives us a set of HTML and JavaScript files in a local folder (c:\Program Files\Autodesk\AutoCAD 2016 Help/English/Help on my system). To parse the files I ended up using some old-school UNIX commands via my OS X environment (which shares... Read more →

Invoking AutoCAD’s UI Finder from JavaScript

On my flight back from Singapore I started thinking about how an app might help people discover what’s new in the AutoCAD UI from release to release. This might also work for custom functionality, but that’s not (currently) my main concern. I was thinking of displaying some kind of palette that cycles through the new commands and features in a release, highlighting the associated ribbon buttons, etc., using the AutoCAD help system’s excellent UI Finder capability. Over the weekend I started looking at how it might work – whether it was possible to call the UI Finder from an... Read more →

Autodesk SoCap

I’m excited to announce the newest member of the Autodesk product portfolio, Autodesk SoCap. The term “SoCap” stands for “Software Capture”, in much the same way as ReCap stands for “Reality Capture”. SoCap is a tool that helps you capture existing software behaviour as code, just as ReCap helps you capture a 3D scene as a point cloud. For SoCap to do its thing, you point it at the piece of software whose behaviour you want to capture – whether desktop software on Windows/Linux/OS X, mobile software targeting iOS/Android* or the URL of a cloud-based app – and SoCap...

Styling your HTML5 progress meter with CSS3

After yesterday’s fun with creating an HTML5-based progress meter for AutoCAD, today we’re going to have some more fun styling it with CSS. To recap, here’s the progress meter that comes “out of the box”, with the default styling from Chromium on Windows. The first thing we need to do for our various changes is to use CSS to disable the default styling, at which point we can then use CSS to override it. progress { width: 100%; -webkit-appearance: none; } Here’s how our progress meter looks when unstyled: Now that it’s stripped bare, we can apply some styling...
