10. FRACTIONAL DIMENSIONS
You can use fractional dimensions, taking into account that the smallest fraction should be 1/64 pul. The dimensions decimal places are used when you need divisions lessthan 1/64 pul. To specify the size of the holes, which is generally drilled with fractional sizes of drill bits, and the sizes of screw threads standardized common fractions are used.
11. DECIMALDIMENSIONS
Decimal Dime When is bounded with decimal places; the decimal part must be expressed with the fewest number of figures possible, in accordance with the requirements of the design and use ofstandardized sizes.
When it is necessary to use the decimal equivalent of fractional dimensions, must be adjusted to three or, preferably, two figures.
12. ANGLE UNITS
Angles are expressed in degrees(°), minutes (‘) and seconds (“) or in degrees, minutes, and decimal minute. It is not necessary to place hyphens between the degrees, minutes and seconds.
The angular dimensions and theirtolerances must be expressed in the same units.
The line of measurement of an angle is an arc traced with the vertex of the angle as center, whenever possible; the position of the dimension varies inaccordance with the extent of the angle and always appears in a horizontal position.
13. SPECIFICATIONS OF SIZE AND STATUS
The size and status are specified by means of two systems based on the rectangularcoordinates and in polar coordinates, respectively. Both systems can be used in the same drawing; simultaneously the choice of system usually depends on the methods of construction. However, asurface or a particular point must be placed through a system, only.
The system of narrow rectangular is one that indicates the distances, situations and sizes by means of linear dimensions measuresparallel or perpendicular to the axs or reference planes which are respectively perpendicular.
The system of limited or polar angle is one that indicates the position of a point, line, or surface by...
