摘要: 从产品的集成信息模型和参数化特征造型的角度论述了尺寸公差模型与特征及几何拓扑模型的关系、尺寸公差模型的构成及采用“OO”方法的表示和它在零件表示及参数化建模中的作用,并给出了在HP9000/425t工作站上实际例子。

关键词: 形状, 尺寸, 公差, 模型

Abstract: he relation between D / T(dimension & tolerance)model and f eature, geometry & topology model,composite of D / T model,its representation with"OO" method and action in representation of part and parametric feature modelling are discussed.An instance of D / T model is also given on HP9000 / 425t work-station.

Key words: shapes, dimensions, allowances, models
