In this study, an intelligent computer-aided design (CAD) system is used to obtain an innovative creation for weave structure designs. The system consists of three main parts: user interface, search mechanism, and the simulation mechanism. The user interface can illustrate eight randomly generated (or default) sample patterns on the monitor for the designer to give each of them a satisfying weighting value as fitness. The search mechanism based on genetic algorithm, can find several desired solutions of weave structure parameters to help the designer create innovative weave pattern. In addition, through the simulation mechanism, the system can simultaneously illustrate the pattern appearance of the evolved weave structure on the monitor for reference. With this system, the inspiration of a designer can be offered, thus the optimal approach solution to fabric design can be achieved.

Keywords: weave structure design, computer aided design, search mechanism, genetic algorithm, woven fabric
