CAD, Master Modeling, & The Diresta Prototype
All the gory details of the Diresta prototype build.
This video includes: a LOT of talking, CAD (Master Modeling), answered one or two questions that came out of the last video, and finally a quick look at the CAM.
9:30 will take you straight to the CAD talk.
EDIT TO ADD: "Master Modelling" is big hammer CAD. Not always necessary, and this example doesn't do justice to how powerful a method it can be, but hopefully gets the point across.
