3.1 SCOPE.
3.1.1 Purpose. This section defines various drafting practices such as drawing scale, lettering, line work, sectioning, and projection, and descriptive geometry applicable to making new engineering drawings and their subsequent revisions. Note: Some material from this section has been relocated to Appendix A1 “Past Practices – Manual Drafting Techniques.” The material may still be pertinent for those companies still producing drawings manually and/or having to revise manually prepared existing drawings, but most of industry has adopted CAD as the preferred medium for generating drawings. Thus, some of this content may be considered as outdated by some readers. To allay this concern we moved the material to the aforementioned Appendix. Some content that is mostly pertinent to manual drawing preparation has been retained in this SECTION as it also applies to CAD-generated drawings.
