CADAM: Rapid Prototyping with Paul Wright (ME) Physical Rapid Prototypes: l For early user testing, l and hands-on feedback l in application context. Zcorp 3D-printer FDM

EE – ME Design Domain Coupling (with Paul Wright, ME) Button Mote Design from NEST Group PCB Contact Pads and Lid Access Holes are considered features. Access Holes are coupled to Contact Pads geometrically by position and size. Alteration of center location of Contact Pads (Electrical Domain) will drastically effect Access Holes (Mechanical Domain) center locations. Coupling

CAD tools for Ideation, Informal Prototyping u Mimick the best of: clay, wire, paper, scotch-tape, styrofoam … u Without the adversity of: messy glue, gravity, strength limits … u Make available pseudo-physical materials that bend as nicely as steel wire, and stretch like a nylon hose, but are strong as titanium, and as transparent as quartz …

Collaborative VR Workstation A student interacting with a Ford Explorer model displayed on the workstation (simulated 3D effect showing the part where the user perceives it to be).

Model Annotation Drawing on a virtual bunny with a brush tool with haptic force-feedback.

Better Surface Design Tools l Based on optimization of a functional l E.g., MVS for aesthetics (Minimum [curvature] Var.) l Fewer controls to manipulate l Explicit consideration of constraints l Automatic attainment of some quality objectives.

Smooth Lines on Smooth Surfaces (+ partitioning along these lines) u Given a smooth surface, and some tiling symmetry group:  cut the surface up accordingly with smooth boundaries.
