In the conceptual design phase, designers not only require an easy way to construct a freeform surface, but also need to modify it intuitively. In this paper, a feature based freeform surface design method is proposed in order to fit the requirement. First, a freeform feature library is introduced as the basis of the system. Freeform features in the library can either be extracted from existing designs or be constructed by designers. With freeform features in the library and basis surfaces, new freeform designs are constructed by Boolean-like operations, such as feature based deformation or union with transition surfaces. In the designed surface, designer can easily modify features with changing highlevel parameters. Finally, several simple examples are presented to demonstrate the effectiveness of the feature based freeform surface design system.
19.-20.09.2002 The series of bi-annual Workshops on Integrated Product Development (IPD) is organised by the Chair of Information Technologies in Mechanical Engineering at the Otto-von-Guericke University, Magdeburg, Germany (Prof. Dr.-Ing. Sándor Vajna). The IPD Workshops are events endorsed by the Design Society. The papers of the IPD Workshops are available for the members of the Design Society for download.
