Design Process
DESIGN PROCESS PROBLEMS
Most people have a traditional understanding of CAD CAM & Rapid Prototyping
Design is not a end it is an exploration
The first output is the beginning of the exploration of design
[ design ]
[ problem setting ] [ problem solving ]
Creativity Engineering
PROBLEM SOLVING
Many computational solutions can be found on the engineering side of design
Lighting software
Structural analysis software
Parametric software
PROBLEM SETTING
If all programs analysis space after the space is completed which programs are built for design?
DESIGN PROCESS
Charles S. Pierce 1839 - 1914
He believed that knowledge will always be comprehended in signs external to the mind which assist the development of thought.
John Dewey 1959-1952
Action and reflection – that we learn from our experiences.

EXPLORATORY PROCESS USING RAPID PROTOTYPING
Search for truth through shape manipulations in CAD & physical representation using RP Devices

HOW DOES THIS WORK IN A COMPUTATIONAL ENVIRONMENT?
Rapid manipulators
Designers want quick, accurate representations of design ideas
Design Fabrication is made of many relationships Relationship of CAD to Devices Relationship of RP Devices to CAD CAM Relationship of RP to assemblies of shapes
