基于Pro-E特征建模、参数化、全数据相关的特点,不仅能实现零部件的参数化实体建模,也可以方便地建立从三维模型到二维工程图的转换,有效地缩短设计时间,提高设计效率与质量,通过对Pro-E特点的讨论,结合VEIC列车清洗机产品设计实例,论述了Pro-E在列车清洗机机械结构部分设计中的应用,介绍了运用该理念进行三维设计的思路、步骤和建模过程。 Based on the features of Pro-E feature modeling, parameterization and full data correlation, it not only can realize the parametric entity modeling of components, but also can easily set up the conversion from 3D model to 2D engineering drawing, effectively shorten the design time , To improve the efficiency and quality of design. Based on the discussion of the features of Pro-E and the design examples of VEIC train washing machine, the application of Pro-E in the mechanical structure of train washing machine is discussed. The concept of three-dimensional design Ideas, steps and modeling process.
