# D Element

Represents different information based on its parent element. The following table describes the D element based on its parent element.

Parent element | Description of D element | Default unit
--- | --- | ---
Scratch | A general-purpose element. | NUM
EllipticalArcTo | The ratio of an arc's major axis to its minor axis. Despite the usual meaning of these words, the major axis does not have to be greater than the minor axis, so this ratio does not have to be greater than 1. Setting this element to a value less than or equal to 0 or greater than 1000 can lead to unpredictable results. | NUM
NURBSTo | The first weight of the nonuniform rational B-spline (NURBS) | NUM
SplineStart | The degree of the spline (an integer from 1 to 25) | NUM
Ellipse | A y-coordinate of a point on the ellipse; paired with x-coordinate represented by the C element. | DL
ConnectionABCD | A general-purpose element. | NUM

## Syntax

    <D
        [Unit]
        [F]
        [Err]
        [V]>
    </D>

## Attributes

Unit

Optional string. Represents a unit of measure. Default values are described in the preceding table. For details about a particular unit of measure, see Units of measure.

F

Optional string. Represents the element's formula. This attribute can contain one of the following strings: "someFormula" if the formula exists locally, "No Formula" if the formula is locally deleted or blocked, or "Inh" if the formula is inherited.

If the attribute is not present, the element's formula is a simple constant, for example, <element>5</element>.

Err

Optional string. Indicates that the formula evaluates to an error. The value of Err is the current value (an error message string); the value of the element is the last valid value.

V

Optional string. Represents the null string condition for a string cell value. In some cases it is helpful to distinguish between an empty string cell null and a null string cell value. This attribute is used to distinguish between these forms of an empty value.
