Creo二次开发--函数(12)--基准坐标系

访问基准坐标系

ProCsys代表了基准坐标系，以下三个函数对基准坐标系的操作。

ProSolidCsysVisit() --遍历实体中的基准坐标系

ProCsysIdGet() --获取指定坐标系的标识符，用于以后在此坐标系中生成几何元素。

ProCsysInit() --由指定的Id值获取坐标系的句柄

/*=========================================================================*\

Function: ProUtilCollectSolidCsys()

Purpose: 返回实体的坐标系集合

Returns: PRO_TK_NO_ERROR - 成功;

PRO_TK_BAD_INPUTS - 无效的参数
