“…By setting a number of appropriate parameters into shape formation rules, different shapes can be generated. In this research area, Taura et al (1998) proposed a method that combines evolutionary design and procedural modelling, in which shapes are represented by sets of rules instead of geometrical data. The approach proposed by Hsiao and Chen (1997) enables designers to create shape variances in three steps based on a general shape grammar.…”

This article presents a 'hands-on' method, targeted towards freshmen product development (or industrial design or engineering design), to create basic form alternatives. The hypothesis that the knowledge and the application of a rational form-generation approach improve the ability to create more and more varied designs is verified by means of an experiment. In this experiment, the effectiveness of the initiated method was measured by comparing the results of a first design session (before initiation of the method) with the results of a second design session (after initiation). The outcome shows definite progress in the basic skills to generate form alternatives: after the initiation, subjects generate more proposals with more variation in surface composition. Parameters like the overall amount of design solutions and the evolution in the variation in surface composition were considered. The experiment indicates that the application of a method can enhance a design process and shows that an analytical and rational approach contributes to the basic skills in the study of form. The two-step manipulation method extends the repertory of possible tools and methods that a designer can implement to cope with the problems concerning the creation of form alternatives.

“…Some attempts to bring this concept into the free-form surface domain-where shape is very complex and analytic surfaces are not sufficient anymore to represent it-have been carried out [9][10][11][12][13][14][15]. A limit of most of these approaches is that they focus on a restricted set of features and try to define features without starting from a rigorous classification.…”

AbstractThis paper addresses the designers' activity and in particular the way designers express an object shape in 2D sketches through character lines and how these lines form a basis for sketching shapes in 3D. The tools currently available in commercial CAS/CAD systems to manipulate the digital models are still not sufficiently suited to support design. In this paper, the so-called fully free-form deformation features (d-F 4 ) are introduced as a modelling method to take into account the curve-oriented stylists' way of working. Both the advantages of a free-form surface deformation method and a feature-based approach are merged to define these high-level modelling entities allowing for a direct manipulation of surfaces through a limited number of intuitive parameters. Such features incorporate several characteristics designed to handle the uncertainties and/or inconsistencies of the designer's input during a sketching activity. In addition, a d-F 4 classification is proposed to enable a fast access to the desired shape according to its semantics and characteristics.

“…In this way the fixed parameter limitations of usual genetic algorithms can be overcome. A special type of cell representation called cell division model is introduced by Taura et al [44]. The shape of a free form object is represented by dots (cells) on the surface of a sphere; the distance between a point on the surface of the free-form object and the center of the sphere is proportional to the local density of cells on the sphere.…”

Genetic algorithms constitute a class of search algorithms especially suited to solving complex optimization problems in engineering. In addition to parameter optimization, genetic algorithms are also suggested for solving problems in creative design, such as combining components in a novel, creative way. Genetic algorithms (GA) transpose the notions of evolution in Nature to computers and imitate natural evolution. Basically, they find solution(s) to a problem by maintaining a population of possible solutions according to the 'survival of the fittest' principle. We present here the main features of GAs and several ways in which they can solve difficult design problems. We briefly introduce the basic notions of GAs, and discuss how GAs work. We then give an overview of applications of GAs to different domains of engineering design.
