Command Options
Option 
Description 
Unit mode 
Specifies the display style of linear measurement. Enter a number between 1 and 5 corresponding to the list:
For metric units, choose 2 (decimal). LUNITS variable stores the style of linear units. 
Number of decimal places for LUNITS 
Specifies the display precision for decimal units. Enter a number between 0 and 8:
This option also affects the display precision of fractions used by architectural and fractional units:

Angular unit mode 
Specifies the display style of angular units. Enter a number:
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 variables stores the style 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:
