UGNX(CAM)认证考试题

UGNX(CAM)认证考试题上海交通大学申模UGS授权培训中心常州机电职业技术学院机械工程系考试说明为了避免考生在考试中因非技能因素影响考试成绩，特此将考试时值得注意的问题说明如下：请考生在考试前仔细阅读本考试说明，按照本说明正确建立考生文件夹并调用电子考题文件和保存考试结果文件。

1：考试前必须核对自己的身份证号和照片，如有错误，报告监考老师并更正。

并按照机器号对号入座。

2：考生文件夹在“资源管理器或我的电脑”中C盘根目录下新建一个文件夹，如没有，由监考老师指定盘符。

文件夹的名称为考生的机器名号。

机器号以监考老师发给你的电子文挡中的机器号为标准。

例如：某个考生的机器名号为1H7，则考生文件夹名为1H7。

3：保存考试结果在建立文件夹后，启动UG软件，在上文件夹下建立UG文件，如做第一题就设1 .prt.做完后一定要保存。

后做第二题就设2.prt。

如此类推。

当要做WORD文挡，就在该目录下新建1.doc。

4：结束工作做完后，举手示意。

不要关机，老师确认后离开考场。
