Creo 阵列(Pattern) 元素树(Element Tree)的获取

获取阵列（特征）-获取元素树-通过名称获取特定元素-检查元素值

1.1 获取特征

ProSelect("feature", 1, NULL, NULL, NULL, NULL, &sel, NULL);
status = ProSelectionModelitemGet(*sel, &item);

1.2 获取阵列元素树

status = ProPatternElemtreeCreate(&item, PRO_FEAT_PATTERN, &elem_tree)

1.3遍历元素树

status = ProElemtreeElementVisit(elem_tree, path, (ProElemtreeVisitFilter)NULL, (ProElemtreeVisitAction)ProUtilElemtreeElemPrint, NULL);

Action 函数

static ProError ProUtilElemtreeElemPrint(
ProElement     elem_tree,
ProElement     elem,
ProElempath    elem_path,
ProAppData appdata)
{
		ProElemId id;
		ProError status = PRO_TK_NO_ERROR;
		int value;
		ProElementIdGet(elem, &id);
		if (PRO_E_GENPAT_REGEN_METHOD == id)//id为元素树结点名称
		{
				ProElementIntegerGet(elem,NULL,&value);
        //不同类型应使用不同Get函数  可以搜索ProElementValueGet
		}
	return PRO_TK_NO_ERROR;
}

其他辅助函数 ProElementArrayCount //统计数量

ProElementArrayGet //注 使用直接获得root结点的话， 顺序目前不清楚 或ProElementChildrenGet
