Number of decimal places in a dimension determines tolerance decimal places. For example: o Dimension “5.10” – Tolerance “+.02” o Dimension “5.100” – Tolerance “+.002” Angular dimensions used when straight lines are not horizontal or vertical. o Expressed in degrees ( 0 ), minutes (‘), and seconds (“) o Also expressed in tenths (.01) or hundredths (.01) of a degree 28 of 45
