Sinopsis

Excerpt from Systems and Practice of the Drafting-Room

A good system of handling and recording the changes made on draw ings is rather difficult to devise. The following system, however, will prove satisfactory. If the change is a slight one, as for instance the change of a dimension, the tracing is changed, the date of change being noted in the lower right-hand corner, and the various prints are changed by the man in charge of that work. If the design is changed, a new tracing is made, the old one marked obsolete, new prints made and put in the books, and the new tracing filed with the old one. In each case a record of every change is made in a book kept for that purpose, and as the parts are all arranged numerically, it is very easy to refer to this record to find the details of the change in making repairs or filling orders for old parts.
