I'm going to have a holiday. I 've been idle recently. I 've sorted out some documents. I don't know if some 2014 works have been put into production. I didn't stay for a long time. There were many plans. Many of them didn't fall to the ground. The problems in the effect drawing mold should not be too big. At that time, it was 2D drawing. At that time, it was not very good at three-dimensional drawing. The front view was mainly, and the side view was very good, but there is no problem in expressing the desired effect.
