Abstract: An information management method of 3D annotation is proposed, which aims at#br# handling the condition of "hedgehog" in 3D annotation information. The annotated features#br# related by geometric dimension and tolerance are grouped by the association relationship graph,#br# the 3D annotation symbols of a part are categorized and displayed with the association#br# relationship graph. The definition and the establishment method of the 3D annotation information#br# graph are studied and the graph search algorithm of the association relationship is established. A#br# prototype software of category management and display of 3D annotation is conducted by the#br# UG/NX7.5 platform and VC++ Language, and a lot of example parts are tested on the software, it#br# proves that the method is feasible and effective.#br# Key words: computer application; 3D annotation; association relationship; graph;#br# management
摘要： 针对三维标注存在的“刺猬”现象，提出了一种基于关联关系图的三维标注
信息管理思想。通过将标注信息关联的零件特征用图结构进行表示，以关联关系图为单位对
标注信息进行显示和分类。研究了标注信息图的定义、建立方法和关联关系图的搜索算法，
基于UG/NX7.5平台和VC++语言开发了原型软件，通过实例验证了该方法的可行性和实用性。
