Before you start drawing in AutoCAD a user needs to set drawing units in AutoCAD. The drawing units set for different applications vary. For example Architects prefer inches while most wood workers prefer fraction. Therefore its essential to select the appropriate AutoCAD Drawing Units for each profession. Also make sure the units that a user selects should match the industry standards else no one will attempt to give you drafting projects or design projects. Unlike AutoCAD, we can also set Civil 3D Drawing Units.
Set Drawing Units in AutoCAD
Architectural Drawing Units : Most American architects will choose this type, which displays units in feet and inches. For example, 12 feet, 61/2 inches is typed as 12′6-1/2″. The hyphen is used to separate inches from fractions of an inch rather than feet from inches.
Decimal Drawing Units : Metric users should select this type. One decimal unit can be equal to one millimeter, one centimeter, or any metric unit that you decide.
Engineering Drawing Units: Like the Architectural type, engineering units feature feet and inches, but the inches are represented in decimal form—for example, 126.500 feet.
Fractional Drawing Units: American woodworkers often prefer to set AutoCAD drawings in fractional units of inches because that is how their work is normally reckoned. For example, 12 feet, 6½ inches reads 150-½″ in fractional units.
Scientific Drawing Units : In scientific units, 12.000E+06 is broken down into two parts: 12.000 indicates 12 accurate to a precision of three decimal places and E+06 indicates the exponential function raised to the sixth power, or 10 × 10 × 10 × 10 × 10 × 10, bringing the total in this example up to 12 million.
