Countersign column refers to a common form of improving important documents such as drawings, construction organization design and construction scheme for approval according to procedures. The countersignature column is a label column used to display information on architectural drawings, the size of which should be 75㎜*20㎜, and the occupation, name and date (year, month and day) represented by the countersignature personnel should be filled in the column; When one countersign column is not enough, another column can be added, and the two countersign columns should be tied. Graphics that don't need countersignature can be set without countersignature column.
