基于Pro/E参数化技术的三维建模方法

摘要

以圆柱齿轮为例设计了一个基于Pro/E参数化技术的三维零件库模型系统.该系统利用特征造型、参数化设计创建通用模型,通过修改零件参数,生成相应的零件模型,不需要逐一创建单个模型,能够大幅度提高设计效率,减少设计工作量,进而缩短产品的开发周期.%The gear case is designed based on Pro/E three-dimensional parametric technology based parts library modeling system. The system uses feature modeling and parametric design to create universal models, then by modifying the component parameters, generates the corresponding component model, instead of creating every single model, which greatly improves design efficiency, reduces design effort, and thereby shortens the product development cycle.
