Explain dimensioning on first-angle drawings.
What will be an ideal response?
Dimensions on first-angle drawings are in metric units of measure. When a numerical value is less than 1, the first numeral is preceded by a zero and a decimal point. For example, the decimal .733 is dimensioned to read 0.733. Whole numbers do not require a zero to the right of the decimal point. Twenty-four (24 mm) would not be written as 24.0; it would be 24 mm.
