Architectural formats produce feet-and-inches displays and assume that each
drawing unit represents one inch. The other formats can represent any
real-world unit.
Precision
Sets the number of decimal places or fractional size displayed for linear
measurements.
Angle
Specifies the current angle format and the precision for the current angle
display.
Type
Sets the current angle format.
Precision
Sets the precision for the current angle display.
The following conventions are used for the various angle measures: decimal
degrees appear as decimal numbers, grads appear with a lowercase g suffix,
and radians appear with a lowercase r suffix. The degrees/minutes/seconds
format uses d for degrees, ' for minutes, and " for seconds; for example:
123d45'56.7"
Surveyor's units show angles as bearings, using N or S for north or south,
degrees/minutes/seconds for how far east or west the angle is from direct north
or south, and E or W for east or west; for example:
N 45d0'0" E
The angle is always less than 90 degrees and is displayed in the
degrees/minutes/seconds format. If the angle is precisely north, south, east,
or west, only the single letter representing the compass point is displayed.
Clockwise
Calculates positive angles in the clockwise direction. The default direction for
positive angles is counterclockwise.
When prompted for an angle, you can point in the desired direction or enter
an angle regardless of the setting specified for Clockwise.
Preview
Displays an example of the current settings for units and angles.
Lighting
Controls the unit of measurement for the intensity of photometric lights in
the current drawing.
