In several application fields, large sized, free-form objects of various soft materials are widely used. Available layered prototyping technologies cannot be applied for fabrication of this kind of objects due to size limitations. The authors have developed a novel approach of layered manufacturing that is the most appropriate for fabrication of objects(More)
Product design is a highly involved, often ill-defined, complex and iterative process, and the needs and specifications of the required artifact get more refined only as the design process moves toward its goal. An effective computer support tool that helps the designer make better-informed decisions requires efficient knowledge representation schemes. In(More)
Although attempts have already been made, computer support of industrial design is still in its infancy, especially of design for aesthetics. The reason is that no methodology is available to incorporate in computer support, design aspects like appearance, pleasantness and human usage of a product. The objective of the paper is to present a methodology that(More)
This paper explores the benefits of design model reuse by reverse engineering. In particular the opportunities of the incorporation of shape (portions) of existing products into the design model are studied. Some of the existing techniques developed for reverse engineering can be applied, provided that these are placed in a dedicated framework. Also, some(More)
Freeform features can be regarded as key elements of shape modeling. Commonly, features are defined, controlled and computed using parameters. In this paper we propose a feature formulation strictly based on the parameterization, as a mapping from an arbitrary set to some domain of interest. This formalism accommodates many of the common representation(More)
This paper provides a systematic approach for copying and pasting of freeform features among existing models of design. Freeform feature as complex high-level shape entity enables a fast creation and modification of a geometric model in the context of both mechanical and aesthetic design. Copying and pasting of freeform feature can enhance not only the(More)
The application of Rapid Prototyping during Conceptual Design is generally called Concept Modelling, without any further reference to what exactly is meant. In this paper the design process will be examined more closely, applying design methodology, and it will be shown that two distinctly different types of activities can be recognized. All (sub)processes(More)
The in-process decisions made by designers strongly influence both the process of designing and the manifestation of the designed artifact. When improvement of designing is intended, the organization of the process and the content of the designers’ decisions have to be concurrently considered. Due to the inherited complexity, application of a computerbased(More)
The use of gestural devices in shape generation is getting more and more accepted. The advantages of this approach are threefold: (a) it provides a highly interactive way of regeneration and modification of free from shape models, (b) it hides the mathematical details of parametric surface design from the user, and (c) this type of analogue input devices(More)
