CAD Illustration Showing Complexity (image) Harvard University Share Print E-Mail Caption A small portion of the CAD design for the Harvard Monolithic Bee illustrates the complexity of folds and joints necessary for its assembly. Using the old, manual process, every one of those parts would have to be cut, folded, assembled, and glued by hand. The bottom image illustrates the 18 layers of laser-cut materials that create the pop-up structure. Credit Images courtesy of Pratheev Sreetharan, Harvard School of Engineering and Applied Sciences.
