CHAPTER 1BLUEPRINTSAnother type of duplicating process rarely used toreproduce working drawings is the photostatic processin which a large camera reduces or enlarges a tracingor drawing. The photostat has white lines on a darkbackground. Businesses use this process to incorporate reduced-size drawings into reports or records.When you have read and understood this chapter,you should be able to answer the following learningobjectives:Describe blueprints and how they are produced.Identify the information contained in blueprints.The standards and procedures prescribed formilitary drawings and blueprints are stated in militarystandards (MIL-STD) and American National Standards Institute (ANSI) standards. The Department ofDefense Index of Specifications and Standards liststhese standards; it is issued on 31 July of each year.The following list contains common MIL-STD andANSI standards, listed by number and title, thatconcern engineering drawings and blueprints.Explain the proper filing of blueprints.Blueprints (prints) are copies of mechanical orother types of technical drawings. The term blueprintreading, means interpreting ideas expressed by otherson drawings, whether or not the drawings are actuallyblueprints. Drawing or sketching is the universallanguage used by engineers, technicians, and skilledcraftsmen. Drawings need to convey all the necessaryinformation to the person who will make or assemblethe object in the drawing. Blueprints show theconstruction details of parts, machines, ships, aircraft,buildings, bridges, roads, and so forth.TitleNumberMIL-STD-100AEngineering Drawing PracticesANSI Y14.5M-1982Dimensioning and TolerancingMIL-STD-9AScrew Thread Conventions andMethods of SpecifyingANSI 46.1-1962Surface TextureBLUEPRINT PRODUCTIONMIL-STD-12CAbbreviations for Use on DrawingsOriginal drawings are drawn, or traced, directly ontranslucent tracing paper or cloth, using black waterproof India ink, a pencil, or computer aided drafting(CAD) systems. The original drawing is a tracing or“master copy.” These copies are rarely, if ever, sent toa shop or site. Instead, copies of the tracings are givento persons or offices where needed. Tracings that areproperly handled and stored will last indefinitely.MIL-STD-14AArchitectural SymbolsANSI Y32.2Graphic Symbols for Electrical andElectronic DiagramsMIL-STD-15Electrical Wiring Part 2, and Equipment Symbols for Ships and Plans,Part 2ANSI Y32.9Electrical Wiring Symbols forArchitectural and Electrical LayoutDrawingsMIL-STD-16CElectrical and Electronic ReferenceDesignationsMIL-STD-17B, Part 1Mechanical SymbolsMIL-STD-17B, Part 2Mechanical Symbols for Aeronautical,Aerospace craft and Spacecraft useMIL-STD-18BStructural SymbolsMIL-STD-21AWelded-Joint Designs, Armored-TankTypeWelded Joint DesignsThe term blueprint is used loosely to describecopies of original drawings or tracings.
