Deepen the specialty of steel structure detail drawing, ok?

Of course, it is not difficult to make detailed drawings of steel structures. Now it is generally made by software, and the joint method is generally provided by the original drawing. Although some joint practices were not in the original design, they can be simply calculated according to the specifications, and then reviewed by the original design unit. As for drawing, software is basically used now. If it is hand-painted, it will be too annoying.
