Brent Burgess commented on this previous post showing how to extend lines in AutoCAD: Is there a different process for shortening lines, or is it similar syntax? A very valid question… unfortunately the Curve.Extend() method only works with points or parameters that are outside the current definition of the curve, so we need to find […]

I've had quite a lot of contact with "laser" technology over the last few weeks. (In case you're wondering about the quotation marks, that's just a little nod to Mike Myers' fantastic Dr. Evil character, who in the Austin Powers movies refers to now-commonplace terms – such as laser – with finger quotes. 🙂 A […]

AutoCAD users who work with multiple reference files – whether DWG, DWF, DGN, PDF, PCG files or raster images – usually want them to be oriented in space (and to overlay) properly. One common way to make this happen is to set the various files up in world coordinates and then attach them at the […]

I've been having a fun discussion with Augusto Gonçalves, based in São Paulo working for our DevTech Americas team, on the subject of QR Codes. Augusto's a technology junky – like many members of DevTech – and has been playing around decoding QR Codes with his mobile phone. QR (from "Quick Response") Codes are two-dimensional […]

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 […]

In the last post we used an API introduced in AutoCAD 2011 to trace boundaries defined by geometry in a drawing. In this post we're going to use these boundaries to define the limits of solid hatch objects which we will – using another new capability in AutoCAD 2011 - make transparent. Here's the updated […]

As alluded to in this previous post, today we're going to see some code that makes use of a very cool new API feature in AutoCAD 2011: the Editor.TraceBoundary() function. This little gem performs something developers have struggled with – and have asked us for – for many years. Previously you had to jump through […]

In the last post we saw a very simple, preliminary exploration of some of the new programmatic capabilities of the in-place MText editor in AutoCAD 2011. In that basic case we just used it to strip off all formatting from an MText object. Now we're going to implement a couple of commands to toggle the […]

Last week we saw a series of simple posts about creating, placing and editing MText. Barry Ralphs asked about the ability to fire off editing commands to the in-place MText editor, which – interestingly – was a new feature in AutoCAD 2011, implemented primarily to enable the control of the MText IPE via AutoCAD's ribbon.

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 […]
