Function Description:
The Drawing Units dialog box is used to control the display precision and formats for coordinates and angles.
Dialog Box Options:
Length
Specifies the unit and unit precision for the current measure.
- Type: Sets the current display format for units of measure. The values include Architectural, Decimal, Engineering, Fractional, and Scientific. The Engineering and 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 measurement.
Angle
Specifies the unit and unit precision for the current angle.
- 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 unit show angle 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 a clockwise direction. The default direction for positive angle is counterclockwise.
When prompting to enter the angle, users can click the direction or enter the angle value without regardless to the Clockwise option.
Insertion scale
Controls the unit of measurement for blocks and drawings that inserted to
the current drawing. If the unit when they created is different from the
specified one, the block or drawing will be scaled when inserting it. The insertion scale is the ratio of the unit used in the source block or drawing and the unit used in the target drawing. Select Unitless to insert the block without scaling it to match the specified units.
Note: When inserting a source block or target drawing, specifying the insertion scale to be
Unitless, users can set it in the Source content units and Target drawing units options of
the User Preferences tab in the Options dialog box.
Sample Output
Displays a sample for the current settings of units and angles.
Lighting
Controls the unit of measurement for the intensity of photometric lights in the current drawing.
Note: In order to control the light source by creating and
using the photometric light, the unit type should not be generic. If the
insertion scale is set to be Unitless, it displays warning information and announce the user render outputting incorrect.
Direction…
Displays the Direction Control dialog box.
