Wow, this is funny. I came across this old post of mine, while doing a Google search. This was at the beginning of my journey to find a method to model organic shapes and characters in CAD. From this point of the original post, I ended up using T-Splines to create the attached mold cavities. Now, even that isn't good enough. Instead of relativity simple objects like these with either profiles or symmetrical shapes, I'm researching methods to take it up a notch or two. Star Wars, the Avengers and other similar projects are in the works. It looks like I've come full circle, only to start my way around it once again.
