5 Importance of Print Reading Drawings are the universal language of industryEngineers, designers, technicians, and skilled workers all use drawingsA print is a copy of a drawing
6 Importance of Print Reading Prints provide the worker with the details of:SizeShapeToleranceMaterials usedFinishOther special treatments
7 Print Reading and Drafting Print reading is closely related to the study of draftingDrafting is the field of study that focuses on the creation of technical drawingsBlueprint is a term originating from one of the earlier copying processes for technical drawings
8 Print Reading and Drafting Prints used to be called blueprints
9 How Prints Are Made Prints are basically a “hardcopy” of a drawing CAD systems can create paper drawings using printers and plottersPrinters and cartridge-based plotters create raster imagesPen-based plotters create vector images
10 How Prints Are MadeCartridge-based plotters create raster images
11 Print Reading Elements Reading a print involves two principal elements: visualization and interpretationVisualization is the ability to “see” the shape of the object based on the various views shown on a printInterpretation is the ability to understand the meanings of the lines, symbols, dimensions, and notes on a print
12 Print Reading Elements Visualization is “seeing” the object based on the views shown on a print
13 Care of Prints When working with prints, observe these rules: Never write on a printKeep prints cleanBe careful when folding and unfolding printsDo not lay sharp tools and parts on a print
14 Care of PrintsUse care when folding and unfolding prints
15 Electronic Formats for Drawings Electronic formats are available that enhance the ability to share prints without sharing the actual CAD dataPortable document format (PDF) is a file format from Adobe and very commonDesign web format (DWF) is a file format from Autodesk and common in environments that use AutoCAD and other Autodesk productsFree viewers are available for both formats
16 Standards for Industrial Prints A standard is a voluntary guidelineThe standardization of engineering drawings for prints has long been established through the American Society for Mechanical Engineers (ASME)
17 Standards for Industrial Prints The American Society for Mechanical Engineers (ASME) is the professional organization that authors and publishes engineering standards related to industrial prints
18 Standards for Industrial Prints The American National Standards Institute (ANSI) is the umbrella organization that serves as an overseeing body for numerous American standards
19 Standards for Industrial Prints The International Organization for Standardization (ISO) is an organization that provides over 18,000 standards on a variety of subjects in the international and global arena
20 List factors that make print reading important. Prints provide the details of size, shape, tolerances, materials used, finish, and other special treatments needed to manufacture a product
21 Describe historical processes and technologies related to prints. An early copying process was a wet process that resulted in white lines on a blue background (a blueprint). A dry process (diazo) was later developed that resulted in blue lines on a white background (a whiteprint or blue-line print). Today, prints are often output from a CAD system to an inkjet or laser printer/plotter.
22 List some terms related to prints. Print, engineering graphics, blueprint, whiteprint, vellum, visualization, interpretation, and standards, among others
23 In general, describe how prints are produced. A print is a copy of a drawing. Traditionally, a print was made with either a wet or dry process (blueprints and whiteprints), but now prints are often output from a CAD system to a printer or plotter.
24 What are two important elements of print reading? Visualization and interpretation
25 List four points related to the care of prints. A) Never write on a printB) Keep prints cleanC) Very carefully fold and unfold printsD) Do not lay sharp objects on prints
26 How can prints be used in electronic (digital) format? By distributing a DWF or PDF file, for example, to the print reader
27 What are the two organizations that have a role in developing standards documents for engineering drawings?American Society of Mechanical Engineers (ASME) and International Organization for Standardization (ISO)
