Details in engineering drawing
Scale: relationship between the measurements of an object on a sheet of paper and the real measurements of the object Reduction (1:2)- drawing smaller than object Full Size (1:1)- same size as object Increase (2:1)- drawing bigger than original
6
Dimensioning Indicating the real dimensions of an object as well as the position of various elements
7
Tolerance: maximum variation of a specified dimension between a measurement on a drawing and real-life measurements
9
Cross-section Reveals interior of an object, exposing hidden details
