摘要
针对概念设计阶段,设计者不仅需要构造自由曲面简易的方法,且需要直观地修改自由曲面的问题,依据自由型特征分类方法,提出了自由曲面设计系统.以自由型特征库作为系统基础,通过基础曲面和库中的自由型特征,可以通过类布尔运算来构造不规则设计,并且设计者能够通过变换高层参数来修改特征.
In the conceptual design phase, designers not only require an easy way to construct a freeform surface, but also need to modify it intuitively. According to taxonomy of freeform feature, this paper proposed freeform surface feature model design system to meet this need. This paper introduced a freeform feature library as the basis of the system, with basis surface and freeform features in the library, freeform design being constructed by Booleanlike operations, and designers can modify features with changing high level parameters.
