Just thought I'd share this link I found to a really cool CAD type machining software. I've been on it for days. Anyway it's really simple to use and I really dig it. If your kinda young like me and havent had a chance to use something like this you'll love it. Take the tutorial. Anyway let me know what ya think and if you know of other similar stuff. Great for newbies and youngins.
