Over the weekend, I had more fun exploring the use of Kinect with AutoCAD. It was prompted by an email I had from a UK-based creative team who are interested in the potential of capturing time-lapse point clouds using Kinect. They were curious whether the quality of data coming from the Kinect device would be […]

As promised in this previous post, I've been playing around with understanding Kinect gestures inside AutoCAD. My first step – after upgrading the OpenNI modules and drivers to more recent versions, which always seems time-consuming, for some reason – was to work out how to get gesture information via nKinect. It turned out to be […]

Since starting to use the transient graphics API in AutoCAD 2009, I've believed that any DBPoints you display would not respect PDMODE (the AutoCAD system variable allowing the user to control how points are displayed). A recent internal discussion was on this very subject, and one of our engineering team, Longchao Jiang, interjected with a […]

I talked briefly about TED, a few weeks ago. A number of Autodesk employees attend this event, including members of our senior staff. During a recent All Hands session, Amar Hanspal – who heads up our Platforms Solutions and Emerging Business division, which includes both Autodesk Labs and AutoCAD Engineering (among other teams) – reported […]

As promised, I ended up burning more that a few hours this evening (after being up very early for meetings this morning), to add orthographic drawing support to the code shown in the last post. It took quite some work, switching between UCS and WCS until my head was more than a little twisted. This […]

A big thanks to Norman Yuan for the technique shown in this post. I stumbled across Norman's post on this topic, and decided to take his code and rework it for posting here, with Norman's permission, of course. Very interesting stuff! 🙂 First things first: you probably don't have a burning need to reinvent either […]

After revealing the purpose for collecting points from 2D geometry in the last post, this post extends the 2D collection code to work with additional 3D objects. I don't know whether it's exhaustive or not – I've added more specific support for Solid3d and Surface objects – but I have no doubt people will let […]

Now it's time to shed some light on the reason for the code in the last post. I wrote it to help address a question that came in from Elson Brown via our Plugin of the Month feedback alias: I have a request for an app that will draw the smallest circle around a polyline […]

The reason for this post may be obvious to some – probably those who are doing this kind of analysis already – and less obvious to others – who will have to wait for the next post to see why it's helpful. 🙂 I won't ruin the surprise, but suffice it to say that for […]

This request came in over the weekend: There is a useful object snap in AutoCAD for the mid point of 2 selected points. I would like a midpoint (average) of 3 (or more) points. Could this work in 3D as well as 2D? It's useful when drawing building surveys, often you triangulate a point from […]
