| 摘 要： | 为把几何模型和尺寸模型有机地结合起来实现信息集成 ,在特征造型中用约束表达零件的尺寸、公差 ;然后利用特征形素自身的尺寸模式 ,以及特征组合过程中的定位约束自动生成尺寸链 ;最后在进行尺寸分层及尺寸布置后 ,根据预先确定的标注规则生成尺寸标注信息 .

| Abstract: | To combine geometric model with dimensional model organically and implement integration of information, the parts' dimension and tolerance are expressed with constraints in feature_based modelling.Then dimensional chains are automatically created by using dimensional model of feature primitive and locational constraints in the process of feature's combination.Finally dimensioning information is created according to dimensioning rules that are predefined after distinguishing dimensions with different levels and arranging dimension. |
