Units Control

Toolbar	none
Pull-down	FormatUnits…
Keyboard	UNITS

When you start the Units command, the first thing you see is the Drawing Units dialogue box, shown on the right. The dialogue box is divided into four main sections. The upper two are “Length”, which refers to linear units and “Angles”, referring to angular units. Settings for linear units and angular units can be made independently and in each case, you can control both the type and precision. In addition, the Angles section also allows you to specify the direction in which angles are measured. See below for more details.

A third section, entitled Drawing units for Design Center blocks allows you to assign a specific unit to the drawing so that when blocks are inserted via the AutoCAD Design Centre, they will automatically be scaled. The final section, Sample Output, gives you a preview of the drawing units as they will be displayed using the current settings.

Specifying Units of Measurement in AutoCAD has three stages which include

Linear Units ( Length )
Angular Units ( Angle )
Precision in Units

Linear Unit Conversion: This helps a user to select from the available Length which include

Architectural – Feet and Fractional Inches
Engineering – Feet and Decimal Inches
Decimal – Metric or SI
Fractional – Whole Numbers and Fractions
Scientific – Decimal value raised to power

Architecture and Engineering mainly exists for users in United States as they still practice these units.

Let’s assume we have 1.5 Drawing Units, the representation in different unit type is listed below.

Decimal – 1.5000

Scientific – 1.5000E+00

Engineering – 0′-1.5000″

Architecture – 0′-1 1/2″

Fractional 1 1/2

Angular Units of Measurement : This helps a user to select from the available Angle which includes

Decimal Degrees – Metric
Deg/Min/Sec – Degree, Minutes, Seconds
Grads – 400 grads – 360 degrees
Radians – 2 Pi radians – 360 degrees
Surveyor – This is based on Compass

To better understand Angular values let’s assume we have 180 Angular Units, the representation in different unit type is listed below.

Decimal Degree – 180.00

Deg/Min/Sec – 180d0’0″

Grads – 200g

Radians – 3.142r

Surveyor – W ( West )

Precision Value : This helps a user to specify the precision value needed for the unit he specifies. Ideally precision value varies in terms of number of zeros after the decimal value. More the zeros, mean the precision is more. Zeros ranging from 1 to 8 exists here.
