-Units

Option

Description

Unit mode

Specifies the units of linear measurement.

Enter a number between 1 and 5 corresponding to the list:

• 1 - Scientific, such as 4.225E+01

• 2 - Decimal, such as 42.25

• 3 - Engineering, such as 3'-6.25"

• 4 - Architectural, such as 3'-6 1/4"

• 5 - Fractional, such as 42 1/4

For metric units, choose 2 (decimal).

(LUNITS refers to the system variable that stores the type of linear units.)

Number of decimal places for LUNITS

Specifies the number of decimal places.

Enter a number between 0 and 8:

• 0 - 0 decimal places, such as 0.

• 1 - 1 decimal places, such as 0.0

• 2 - 2 decimal places, such as 0.00

• 3 - 3 decimal places, such as 0.000

• 4 - 4 decimal places, such as 0.0000

• 5 - 5 decimal places, such as 0.00000

• 6 - 6 decimal places, such as 0.000000

• 7 - 7 decimal places, such as 0.0000000

• 8 - 8 decimal places, such as 0.00000000

This option affects the precision of fractions in architectural and fractional units:

• 0 - 0 fractional precision, such as 1

• 1 - 1/2

• 2 - 1/4

• 3 - 1/8

• 4 - 1/16

• 5 - 1/32

• 6 - 1/64

• 7 - 1/128

• 8 - 1/256

Angular unit mode

Specifies the type of angular units.

Enter a number between 1 and 5:

• 1 - Decimal degrees, such as 90.0

• 2 - Degrees, minutes, and decimal seconds, such as 90d0'0

• 3 - Grads, such as 100.00g

• 4 - Radians, such as 1.57r

• 5 - Surveyor's units, such as N 00d0'0"E

There are 400 grads in a circle.

There are 2*pi radians (approximately 6.282) in a circle.

The N and E in Surveyor's units refers to North and east.

(AUNITS refers to the system variable that stores the type of angular units.)

Number of decimal places for angular units

Specifies the number of decimal places.

Enter a number between 0 and 8.

Angle 0 direction

Specifies the direction for 0 degrees.

Enter an angle, or pick two points in the drawing.

The default is the positive x axis.

You can also rotate the drawing through the Snap command's Rotate option.

Do you want angles measured clockwise?

Specifies the direction in which to measure angles:

• Yes - measures angles clockwise.

• No - measures angles counterclockwise (default).

Description

Scientific Linear Units

Chooses scientific as the working units.

Decimal Linear Units

Chooses decimal (metric) as the working units.

Engineering Linear Units

Chooses engineering as the working units.

Architectural Linear Units

Chooses architectural as the working units.

Fractional Linear Units

Chooses fractional as the working units.

Relative

Displays relative coordinates in the status bar.

Absolute

Displays absolute coordinates in the status bar.

Off

Displays coordinates only when points are picked.

Properties

Opens the Coordinates section of the Settings dialog box.

Coordinates

Specifies how coordinates are displayed in the status bar:

• Update coordinates only when selecting points - equivalent to Off.

• Coordinates always show pointer location - equivalent to Absolute.

• Coordinates in polar form for point, distance and angle selection - equivalent to Relative.
