Abstract

Abstract: Aiming at the problems of incomplete redundancy judgment and low efficiency of complex model checking in the completeness tests of 3D dimensioning, the concepts of equivalent dimension sets and equivalent nodes were proposed, and a 3D dimensioning completeness test algorithm was realized based on equivalent size. The equivalent dimension sets were created in the dimensioning processes, the redundancy judgment of equivalent dimension was realized based on the equivalent dimension sets, and the redundancy tests of dimension chain were carried out based on the undirected graph composed of equivalent nodes. After the dimensioning was completed, the dimension missing check was converted into surface feature constraint judgment. In the three-dimensional labeling system designed in CREO software, several models with different characteristics were tested. The results show that the algorithm may accurately judge the equivalent dimension redundancy, dimension chain redundancy and dimension missing, and effectively improve the overall efficiency of labeling.

Key words: , 3D dimensioning, completeness test, equivalent dimension, surface feature constraint

摘要： 针对目前三维尺寸标注完备性检验存在的冗余判断不够完整和复杂模型检查效率低等问题，提出等价尺寸集与等价节点概念，实现了一种基于等价尺寸的三维标注完备性检验算法。在尺寸标注过程中创建等价尺寸集，以等价尺寸集为基础实现等价尺寸冗余判断，基于等价节点构成的无向图进行尺寸链冗余检验；在尺寸标注完成后，将尺寸缺失检查转换为面特征约束判断。在CREO软件设计的三维标注系统中对多个具有不同特征的模型进行实例测试，结果表明该算法对等价尺寸冗余、尺寸链冗余、尺寸缺失情况均能准确判断，且有效提高了标注的整体效率。
