I finally came up with a succinct title for this post after struggling with "Shading a face of an AutoCAD solid with a transparent hatch pumped through the transient graphics sub-system using .NET". Or words to that effect. 🙂 So yes, this post shows how to create a temporary hatch with transparent shading that then […]

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 […]

Over the holiday season I bought myself an external 21.5" LCD multi-touch screen from Albatron. I'd been meaning to play around with multi-touch technology (on a full PC rather than a smartphone) and the arrival of Alias Sketch for AutoCAD 2010 on Autodesk Labs seemed like the perfect opportunity. AutoCAD doesn't currently have in-built multi-touch […]

Back in this previous post we looked at some code to sweep an AutoCAD surface using .NET. As I mentioned in a later update, it's possible to also sweep an AutoCAD solid using .NET (since AutoCAD 2010: prior to that one had to use ObjectARX). I've just received a comment asking me to show how […]

Next week Fenton Webb, from DevTech Americas, will be presenting a free webcast on the 3D capabilities of AutoCAD's APIs. Here's Fenton's synopsis: "If your product has always been 2D and you are now considering moving to 3D or if you are simply interested in finding out about the different API's that are available to […]

Back in April I posted an IronRuby sample that I had hoped would cause AutoCAD to jig a box in 3D, just like its IronPython counterpart. The sample didn't work with IronRuby 0.3, but recently David Blackmon got in touch to let me know he had a version of the code working with IronRuby 0.9. […]

As promised in this previous post, we're now going to an update to Zeljko's triangulation code which creates Solid3d objects with a user-specified depth from our SubDMesh. Here's the C# code with the new/modified lines in red (here is the .cs source file). I've modified the code to reformat it and to provide the various […]

I'm just settling in after a week of very enjoyable paternity leave (thanks to all of you for your congratulatory messages :-). I have a few topics planned for the next few weeks, but in the meantime I'm going to post some code provided by our old friend Zeljko Gjuranic as a follow-up to this […]

I might also have called this post "Overruling AutoCAD 2010's entity display and explode using Boo", as it complements the equivalent posts for C#, F#, IronPython and IronRuby, but I felt it appropriate to combine the post with an introduction to what Boo is all about. What is Boo and how did I come to […]

As mentioned in this previous post, where I gave the same treatment to IronPython, I've been trying to get display and explode overrules defined in IronRuby working properly in AutoCAD. IronRuby is still at version 0.3, so this effort has been hindered by a number of CLR interop bugs (it turns out). I finally managed […]
