摘　　要：在介绍、分析Pro/Engineer中实现参数化设计各种方法的基础上,提出了一种基于三维模型的广义参数化设计方法。首先采用人机交互方式建立零件模型,提高了模板(即原始模型)的建立速度,之后添加尺寸约束、关系。通过该方法,用户只需输入驱动尺寸既可再生新零件,减少了用户交互时间,提高了建模速度。Some methods on parameterized modeling in Pro/Engineer were introduced and analyzed. A generalized parametric design method based on 3D model was proposed. First, parts which were used as templates were modeled by human-computer interaction, by this way, parts modeling can be speed up, and then measurement restriction and relation were appended. According to this method, a new part was produced only by inputting driving measurements, so users＇ interactive time was decreased and models can be generated more quickly.
