Drawing Issue Numbering

When an isometric drawing is reissued after a change, the issue number of the drawing can be updated and plotted automatically by Isodraft. The issue number is taken from the REV attribute of the pipe being detailed. See the MARK REVISION command.

When this facility is used, the issue number is shown in the title block in the bottom right-hand corner of the isometric (see the example below). The default text is ISS: n, where n is the issue number. This can be changed to REV: n or any other text by using the ATEXT (alternative text) command to change ATEXT 254.
