I’d wager that 95% of CAD users don’t know what “Curvature” continuity really is in the mathematical sense, much less how it makes sense in the broader context of surfacing. Here we’ll look at the basic principles of “continuity”, and use these principles as the basis for a longer-term study on class a surfacing continuity. [...]

Conics 101
Some of you might not know what I’m talking about when I ramble on about “conics” in CAD. In this short video, I’ll explain what conics are, and the basic mathematical and practical ideas that underpin their use in CAD. Sound like a party? Oh yeah, baby. It’s geek-out time.
Capital Costs
Going freelance has made me think long and hard about the cost of the tools that I use day-to-day. Starting a freelance design business is capital-intensive! Even the most basic realistic setup will run about $8800, and buying a reasonable parametric modeler will bump you up to $12800! Forget about getting a “real” CAD package; [...]
class-a
Recently a friend of mine approached me with a proposition: he asked if I would like to partner with him on a new industry website specifically for class-a surfacing (ClassASurfacing.com). A few days later, and I’ve created my first tutorial on the basics of geometric continuity in CAD. I’m very excited about this project! It [...]
