Unit Settings

The Units command sets units of linear and angular measurements through the Settings dialog box.

The -Units command sets units of linear and angular measurements in the command bar.

To define the Drawing Units settings

Type units in the command bar, then press Enter.
The Settings dialog opens, showing the Drawing Units settings.

Name	Title	Description
INSUNITS	Insertion units	Controls the automatic when inserting blocks or attaching xrefs or images.
MEASUREMENT	Measurement	Determines whether Imperial (ANSI) or Metric (ISO) hatch pattern and linetype files are used.
UNITMODE	Unit mode	Specifies how imperial units display.
LUNITS	Linear unit type	Sets the linear unit type.
LUPREC	Linear unit precision	Determines the display precision for linear units in dialog boxes and the Coordinates field in the Status Bar. The LUPREC system variable affects the display precision only, not the internal precision.
AUNITS	Angular unit type	Sets the angular units display format.
AUPREC	Angular unit precision	Determines the display precision for angular units in dialog boxes and the Coordinates field in the Status Bar. The AUPREC system variable affects the display precision only, not the internal precision.
ANGBASE	Angular base	Sets the origin for angular units relative to the current coordinate system . If ANGBASE = 0, angles are measured from the X-axis.
ANGDIR	Angular direction	Sets the positive angle direction. If ANGDIR = 0 or OFF, angles are measured counter clockwise (default setting).

Entering angles

Although the AUNITS system variable defines the angular unit type, you can enter angles in any of 5 formats:

Decimal degrees: 37.456
Degrees / Minutes / Seconds: 37°27'22" or 37d27'22"
Gradians: 41.6178g
Radians: 0.6537r
Surveyor's Units: N52°32'38"E or N52d32'38"E
Surveyor's units are measured from the North (N) or the South (S) to the East (E) or to the West (W).
