The District uses 7 line weights in the production of all drawings. These line weights are numbered 0 through 6, with 0 being the lightest line and 6 the heaviest. Line weights 5 and 6 are rarely used.
The IPLOT Pen Table defines the thickness of each line. Consultants who do not use IPLOT for plotting final drawings shall modify their plotting software or pen tables to emulate the line weights used at the District. If necessary, request a sample of line weights from the District CAD Contact.
