In UGS,Object is desgned by a unsignd int number - tag. But tag would be changed after next open,we usually ues id - an unsignd int number got from handle - the only expression to delegate the object.
在UGS软件中，对象标示被设计为无符号整形——tag，但是tag在每次打开文件后都会变化。
这个软件能够识别对象的唯一标示——ID，一旦对象生成，ID就确定了。
对于UG NX二次开发人员很有用。
Useing the plugin ,you can show the id of selected objects and highlight the object with given number.
