Fellow freelance illustrator and former classmate Cody Walker has been writing some great technical illustration tutorials for Adobe Illustrator over at VectorTuts.com.

So far he’s covered orthographics, isometric projection, one-point, two-point and three-point perspective, as well as some great tips on using Illustrator in general.

These tutorials are a great start for anyone interested in technical illustration, but even graphic and web designers can benefit from learning how to create a quick 3D effect from 2D artwork.
