The rapid physical realization of a product from a CAD model prior to full scale manufacturing presents a challenging task for industrial companies, as well as academic researchers. This paper presents a rapid and flexible prototyping system designed to directly connect a CAD system (Alias) with a software based DMAC (Direct Machining And Control) controller. The overall architecture is presented and the tool path planning, animation, and direct machining under Alias are explained. The implementation of the proposed prototyping system is realized on a three-axis mill. An example of milling a real surface through this direct CNC system is presented and conclusions are drawn.

The role of computers and of computer-aided design tools for the creation geometrical shapes that will be judged primarily by aesthetic considerations is reviewed. Examples are the procedural generation of abstract geometrical sculpture or the shape optimization of constraint curves and surfaces with some global "cost" functional. Different possibilities for such "beauty functionals" are discussed. Moreover, rapid prototyping tools based on layered manufacturing now add a new dimension to the visualization of emerging designs. Finally, true interactivity of the CAD tools allows a more effective exploration of larger parts of the design space and can thereby result in an actual amplification of the creative process.

Virtual prototyping of cloth has recently become a topic of increasing interest both in computer graphics and computer-aided design for industrial fabric or apparel production. Aiming at an accurate simulation of garment shapes, this paper presents a physics-based system for virtual cloth modelling, specifically conceived for design purposes and targeted to the clothing industry. This environment should allow the designer/modellist to validate her/his style and design options through the analysis of garment virtual prototypes and simulation results in order to reduce the number and role of physical prototypes. To this end, a complete physics-based model has been defined, oriented to actual complex-shaped apparel, incorporating aspects related to garment's shape and structure (e.g., 2D profiles of basic patterns and multi-layered parts), mechanical/structural properties of fabric materials and multi-layered parts, and design/manufacturing processes (e.g., ironing, starching). The physical garment's model has been developed upon a particle-based model embedded in constrained Newtonian dynamics with collision management. The system has been validated within European and national projects, simulating several female and male garments with different levels of design complexities and directly provided from involved clothing companies.

RAPID prototyping, PROTOTYPES, COMPUTER-aided design, COMPUTER-aided engineering, and MANUFACTURING processes
The article focuses on the development of rapid prototyping (RP) industry in the U.S. It is noted that the industry exist with prototypes being developed in hours rather than in days or weeks. The application of direct digital manufacturing (DDM) is considered as the latest RP development due to the increasing sophistication of the parts being developed. DDM begins in design just as the computer-aided design (CAD) of a jigsaw.

A VR-based system for the virtual prototyping of shoes employs a user interface that mimics shoe designer's conventional work style, using a pen and a shoe last as 3D proxy objects. Users sketch design lines onto the last. For this task, the system employs an algorithm for real-time sketch recognition on curved surfaces. On the basis of the framework of curves, the system creates further design elements (for example, leather pieces) to complete the model. Users can employ three pen-based interaction metaphors to interact directly with design elements, to input values, or to make choices from a menu. A user study shows that conventional designers can easily learn and apply these interaction methods. [ABSTRACT FROM PUBLISHER]
