西安最近的天气已经开始慢慢转凉，上海的天气还是依然很热吗？
请在辛苦工作的同时，一定注意保重身体。
上次您来西安的时候，我也曾向您提起过调换岗位的事情，
但由于自己准备不足等种种原因，没有正式提出。
在您走后的这段时间里，我抓紧时间学习设计软件及各方面的相关知识。
现在已经可以独立地完成一般的3D建模等工作。虽然我没有良好的机械方面的背景。
但是我相信通过自己的努力与学习，可以胜任一个CAD工程师的日常工作。如果可以的话，我想支持日本的机械类的工作。
另外，西安是我的家乡，我想我有一个比较好的稳定性。
目前我自己现有的日常工作也比较繁忙，而且在白天又没有可供练习使用的软件。
出于自身想学到更多的知识，有一个更大的发展，虽然我也觉得这个请求非常的无理，,但是我仍希望您能给我一次机会，批准我转入CAD工程师的岗位。
最后，祝您工作顺利。
Recently, Xi'an’ weather is turning cool, how about shanghai? Is it still hot?
Except hard work, please be kindly take care of health.
The last time you come to Xi'an, I have talked you to swap positions.
However, I lack of preparedness at that time, so did not formally proposed.
Since you leave to xi’an, I lose no time to study of mechanical design software and other knowledges.
Now,I can independently complete the general 3D modeling works and so on. Although I do not have a good mechanical background.
But I believe that through their own efforts and learning, I could do a CAD engineer's daily work. If possible, I would like to support the Japan division's machinery work.
In addition, Xi'an is my hometown, I think I have a good stability.
Currently I am available daily work more busy, and did not use the software for practice.
Currently my available daily work more busy, and didn’t have the software for practice at day.
I would like to learn more knowledge, have a greater development. Although I find this request very unreasonable, but I still want you to give me a chance, allow me to transfer CAD engineering positions.
The finally, wish you success in your work.
