Dennis,
This issue is comprehensively addressed in CSI's Uniform Drawing System (UDS), which is an integral component of the U.S. National CAD Standard (NCS),
www.nationalcadstandard.org. NCS builds upon and extends the earlier ConDoc system, no longer published, that was mentioned in a post by another member.
