Once again, members of the DevTech Americas team have put together an entertaining and informative DevCast session on AutoCAD's APIs. This time, Gopinath Taget joins Stephen Preston and Fenton Webb to present a number of interesting topics: boundary tracing, associative surfaces, 3D laser scanning and point cloud filtering. I'll be covering boundary tracing via this […]

This one is a bit of an experiment: our first "fun" Plugin of the Month (fun in that it doesn't serve a serious work-related purpose that I can think of :-). I've post earlier versions of the code to this blog, but thought I'd post and share the latest & greatest. Scott has kindly announced […]

Last week we looked at a preliminary version of this application that made use of an EntityJig to display a Spirograph as we provided the values needed to define it. While that was a good start, I decided it would be better to show additional graphics during the jig process, to give a clearer idea […]

After my initial fooling around with turning AutoCAD into a Spirograph using F#, I decided to come back to this and bolt a jig on the front to make the act of making these objects more visual and discoverable. The process was quite interesting – I'd created jigs from Python and Ruby, but not from […]

Thanks to Stephen Preston from DevTech Americas for the code that originally inspired this post. A nice little one to start the week. We're going to ask the user to select a bunch of lines and we'll then go through and edit each one, extending it in both directions by a quarter of its original […]

We have a number of candidate "Plugins of the Month" currently in the pipeline – including Inventor versions of Screenshot and Clipboard Manager as well as a tool to streamline batch plotting from AutoCAD – but unfortunately none were looking ready enough to count on for January's posting. So yesterday I dipped into the plugins […]

Thanks to Philippe Leefsma, from DevTech in Europe, for the ObjectARX code that inspired this post. In AutoCAD it's possible to create non-rectangular viewports in paperspace using a variety of closed curve objects: circles, polylines (2D, 3D and lightweight), ellipses, regions, splines and faces. In this post we're going to see some code that creates […]

I've been toying for some time with the idea of writing some code to turn AutoCAD into a Spirograph, a device which I'm sure fascinated and inspired many of you as children (just as it did me). I chose to write the application in F# for a couple of reasons: this type of task is […]

Thanks to all who provided input on this last post, where I asked for guidance on how best to design the command-line interface for the Screenshot application, the proposed Plugin of the Month for November. The current code is based largely on this previous post, but may end up being extended - in time - […]

In the most recent part of this series, we looked at one possible mechanism to allow points to be moved along a network of curves, extending the first part in this series, which focused on the case of a point on a single curve. This post is going to focus on something slightly different: it's […]
