Drawing Units

Type:

Current format of linear units.

Available formats in the drop-down list:

·         Architectural

·         Decimal

·         Engineering

·         Fractional

·         Scientific

Precision:

Accuracy of current linear units.

Type:

Current format of angle units.

Available formats in the drop-down list:

·         Deg/Min/SEC

·         Grads

·         Decimal degrees

·         Radians

·         Surveyor’s units

Precision:

Accuracy of current angle units.

Base Angle:

Direction of base angle.

Available formats in the drop-down list:

·         East

·         North

·         West

·         South

·         Pick angle – by specifying two points in the graphic area.

Clockwise

To change positive direction to measure angles to clockwise.

Display in “input” format

Enables/disables display of drawing units without spaces.

Units to scale inserted content:

Units to measure blocks and external references, inserted in a document. If a block or inserted document was created with units which do not coincide with the units set in this section, the block or inserted document will be scaled to the specified units.  Scale is defined by the ratio of units in an inserted document and a current document.

If the Undefined option is selected, the insertion is performed without scaling.

Sample output

Preview of current linear and angle units set in the dialog box.

Units for specifying the intensity of light:

Selecting light intensity units and lighting type. The following options are available in the drop-down list:

·         Generic – standard lighting is included without lighting fixtures, lighting intensity units are not used (system variable LIGHTINGUNITS = 0);

·         American – photometric lighting is included, American units of lighting intensity are used - Foot-candle (LIGHTINGUNITS = 1);

·         International – photometric lighting is included, the lighting intensity units of the International System of Units (SI) are used - Lux (LIGHTINGUNITS = 2, default value).

Report formats:      (Examples)

1.  Scientific         1.55E+01

2.  Decimal      15.50

3.  Engineering      1'-3.50"

4.  Architectural   1'-3 1/2"

5.  Fractional         15 ½

With the exception of Engineering and Architectural formats,

these formats can be used with any basic unit of measurement.

For example, Decimal mode is perfect for metric units as well

as decimal English units.
