Selected front view should describe the part the best. All dimensions must be in decimals. All Dimensioning must be described either in inches or metric, if necessary either one of them can be described in parenthesis. All hidden lines should be removed unless necessary. Dimensions shouldn't be duplicated. Hidden lines shouldn't be dimensioned unless necessary. Dimensioned shouldn't be placed on the body unless necessary.
