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.
