sketchup

Skethcup is a pretty interesting program. Its like this program I used in one of my other classes, nx5. You can create shapes into 3 dimensional space. From there you can put together the individual pieces you made and construct a apparatus or structure anything you want. But the components only move In restricted space meaning that their physical size and being is taken into account when being constructed. Basically what im trying to say is that their both pretty helpful and interesting programs.
