应用扩展实体数据的零件号标注方法的研究与实现

Xdata Application in CAD System on Labeling of Parts Number

通过扩展实体数据的创建、标记和解释实现了零件号的自动生成,以及通过扩展实体数据对零件标号的查询和排序等技术,实现了零件号的修改、零件号的删除、零件号的插入等功能,并给出了算法。所开发的系统可满足装配图中零件号标注的各种需要,有效地提高了工作效率,在工程绘图中具有较大的实用价值。

The method of automatic labeling of parts number is realized by creating, labeling and explaining of Xdata. Using the technology of inquiring and sorting by Xdata, many functions, such as revision, deletion, insertion of part number, are realized, as well as the algorithms. The system can satisfy various demands of labeling parts number in assembly drawing with more efficiently.
