| 摘 要： | 描述了一个基于手绘草图的三维设计系统，并给出了该系统的体系结构．该系统采用以草绘手势规则和草图语义自动机为基础的设计与表达的思路，描述了草图语义的获取、表达和理解方法，从而较好地支持了早期的三维产品概念设计．该系统以手写笔和手写板为交互输入设备，能够自然、高效地进行一些复杂的三维实体和三维场景设计．

| Abstract: | A sketch-based 3D CAD system is presented in the paper, and a group of sketch gesture rules and sketch semantics automatic machines construct the architecture of the system. It describes the method of capturing, expressing and understanding the sketch intent. This method makes the system more effective during 3D CAD conceptual design. The prototype system uses a grip pen and a digital tablet as its input devices, and it can construct some complicated 3D solid body and 3D scene in a natural and rapid way. |
