为了解决原有调绳工艺的复杂性,通过Pro/E对调绳装置进行参数化设计,利用VC来驱动Pro/Toolkit库函数实现模型尺寸的检索、修改和更新。对于复杂模型,通过添加关系约束函数以减弱参数化设计过程对模型的依赖性,增加了参数化设计的灵活性,并缩短了设计人员进行参数化设计的周期。 In order to solve the complexity of the original transfer rope process, parametric design of rope adjustment device was carried out by Pro / E. VC was used to drive Pro / Toolkit library function to retrieve, modify and update the model size. For complex models, by adding a relational constraint function to reduce the dependency of the parametric design process on the model, it increases the flexibility of parametric design and shortens the period of parametric design.
