2 LECTURE #1 Design Theory of Design Fabrication Fabricating Space

3 [1] Design Process

4 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

5 [ design ] [ problem setting ] [ problem solving ] Creativity Engineering

6 PROBLEM SOLVING Many computational solutions can be found on the engineering side of design Lighting software Structural analysis software Parametric software

7 PROBLEM SETTING If all programs analysis space after the space is completed which programs are built for design?

8 DESIGN PROCESS Charles S. Pierce He believed that knowledge will always be comprehended in signs external to the mind which assist the development of thought. John Dewey Action and reflection that we learn from our experiences.

11 EXPLORATORY PROCESS Search for truth in manipulation & representation

12 Problem Setting Concept-Schematics- Programming Design and Development Construction Documentation Construction Administration Problem Solving

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

14 HOW DOES THIS WORK IN A COMPUTATIONAL ENVIRONMENT? object creation reflection object manipulation reflection

15 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

46 OUR WORLD IS COMPOSED OF EUCLIDIAN GEOMETRIES Repetition of building parts Means of Measurement Process of Construction NON EUCLIDIAN DESIGN No Repetition of building parts No Means of Measurement Process of Construction based on Self Assembled Parts

47 FABRICATION STUDIOS RP devices to start the process Self Assembled parts A variety of cutting and building devices
