COMPUTER-aided design, COMPUTER-aided engineering, RAPID prototyping, ENGINEERING, and DESIGN
Feature modeling has simplified, improved and accelerated the Computer-Aided Design (CAD) process. However, this modeling paradigm still has some serious shortcomings. Firstly, its domain is currently restricted to regular and simple freeform shapes. Secondly, most current feature modelers do not allow new class definitions, but instead provide design with predefined classes. In this paper, we propose a method to solve these shortcomings as follows. The shape domain is extended to include more general freeform features. To achieve this, a generic freeform feature taxonomy is developed. New feature classes can then be defined by deriving from this taxonomy, at any level of abstraction per design intent, through an object-oriented approach. In particular specification of class parameters and constraints, in the new classes, is demonstrated. [ABSTRACT FROM AUTHOR]

COMPUTER software, ORIGINAL equipment manufacturers, ENGINEERING, RAPID prototyping, and COMPUTER-aided design
The article discusses the benefits of using PowersShape design for manufacturing software and PowerMill Computer Numeric Controlled (CNC) programming software from Delcam to 3-Dimensional Services Group in producing prototypes for an auto original equipment manufacturer (OEM). All firms in the Group offer full service engineering and rapid prototyping services. It is stated that the software solution was able to turn computer aided design (CAD) data into validation parts in less than 24 hours.
