Set Angular Units
You can specify that positive values of angles are measured either clockwise
or counterclockwise, and the direction of angle 0 (usually East or North). You
can enter angles using grads, radians, or surveyor's units or using degrees,
minutes, and seconds.
If you use surveyor's angles when specifying polar coordinates, indicate whether
the surveyor's angles are in the north, south, east, or west direction. For
example, to enter the relative coordinates for a property line that is 72 feet,
8 inches long with a bearing of 45 degrees north, 20 minutes, 6 seconds east,
enter @72'8"<n45d20'6"e.
Understand Rounding and Precision
When you specify the display precision of units, the values for coordinates
and distances are rounded off. However, the internal precision of coordinates
and distances is always maintained regardless of the display precision.
For example, if you set the display precision of decimal-format units to 1 (or
0.0), the display of coordinates is rounded to one place after the decimal point.
Thus, the coordinates 0.000,1.375 are displayed as 0.0,1.4, but the internal
precision is still maintained.
