遇事多看书

今天上午一直在看机械设计手册。

不知道焊缝怎么画。肖工的图，网上的资料，让我越看越糊涂。突然想起来，机械设计手册上应该有这方面的资料。

于是去二楼把第一卷搬了下来。第一卷里，不仅有焊缝，还有公差、配合、标注等等，我所有的疑惑都能在这里找到最权威的答案。

与它相见恨晚啦！

This morning I was reading the handbook of mechanic design.

I didn't know how to draw the welds.I didn't complete belive Engineer Xiao's examples and the files of internet.Suddenly I had an idea that the handbook should had files about welds.

I  went to the second floor immediatly and took the first volumes down.There are welds tolerance fit and so on,it can solve all my problem.

I regret we didn't meet sooner.
