For example, a chair may be drawn so that each 1/4” represents 1 inch (1”=4”). To accurately determine the distances on a drawing you must match the scale of the drawing to the proper measuring scale.example title block6SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2009, Georgia Institute of TechnologyMeasurement DevicesA scale is a tool used to measure something.The combination scale you purchased has 6 different scales:-- 10, 50, 32, 1/4-1/2, Full Size, and metric(mm).7SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2009, Georgia Institute of TechnologyExample ScalesExamples of scale specifications using these scales:Scale Unit;Divisions Examples of scales used10 1”;10 1”=1” 1”=10’ 1”=100’ Decimal50 1”;50 1”=5” 1”=50’ 1”=500’ Decimal½, ¼ ½”;16, ¼”; 8 ½, ¼, 1=2 1=4, inch fractionsMetric 1 mm;10 1mm:1mm 1:100 1mm:1 meterFull 1”;10 Full size, Decimal (Ruler)32 1”;32 Full size, inch fractions (Ruler)8SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2009, Georgia Institute of TechnologyCivil Engineer Scales9SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2009, Georgia Institute of TechnologyReading an Engineer’s ScaleIf the scale is 1” = 50’, read 64’10SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2009, Georgia Institute of TechnologyReading a Mechanical ScaleFor a scale of ½ or 1”=2”, read 3 1/8”11SheetCourse: Introduction to Engineering Graphics and Visualizationcopyright 2009, Georgia Institute of TechnologyReading a Metric ScaleFor a scale of 1:1000 SI, read 37,000 mmor 37 Meters.
