The purpose of this paper is to demonstrate that the introduction of computer graphics to the field of automated structural design alleviates many of the problems inherent in the use of high speed digital computers in structural design by permitting an interaction between the designer and the design program.This interaction provides significant advantages over conventional computer-aided design. The input of data is facilitated, and the designer can verify that the data are correct by having them displayed on the screen. The designer is able to control the optimization while it is in progress. By examining the results after each iterative cycle, he is able to implement design decisions and terminate the design when satisfactory convergence is achieved. Foremost, the designer is given an intuitive knowledge of the structural problem he is dealing with because he is able to examine in one session with the computer, the effect of various structural parameters, such as column spacing and displacement constraints.

Developable surfaces are defined to be locally isometric to a plane. These surfaces can be formed by bending thin flat sheets of material, which makes them an active research topic in computer graphics, computer aided design, computational origami and manufacturing architecture. We obtain condition for developable and minimal ruled surfaces using rotation frame. Also, the validity of the theorems is illustrated with examples.

Prototype Design

The proficiency of Computer Aided Design (CAD) to save, communicate and render realistic virtual prototypes allows for easier communication and review of proposed design decisions via design reviews. However, the use of virtual prototypes is limited by the realism of the human computer interface. This paper builds on previous research investigating if increasing the realism of input and output interactions between subjects and virtual prototypes will affect user’s ability to analyze an assembly for errors. For this end, two experiments were conducted which asked participants to perform design reviews on assembly models and identify errors in the assembly. The first experiment tested virtual prototype output display factors through subject point of view movement and virtual prototype rotation. The second experiment tested human input factors using different controller setups. It is expected the more realistic virtual prototype rendering and controller input experience will result in more accurate design reviews.
