摘要
以图形元素和关联算子为基础定义结构单元 ,并赋以特定工程含义 ,使之成为包含结构信息和图形信息的基本设计单位 ;定义了主矢的概念来描述单元的总体特征 ,归纳了三种类型的关联约束 ,建立了单元化结构模型 。
In order to accelerate the process of making variational 2D mechanical drawing, graphic primitives such as lines and arcs are linked together according to certain correlation constraints to form structural elements with specific functional meanings A single vector is used to determine the positioning, orientation and main control dimension of each structural element in a part drawing Three kinds of correlation constraints are worked out to uniquely describe the way of assembling structural elements into the desired part In such a way, the structural variational design of mechanical part is realized quite easily and quickly
