# YDyn Element

Specifies the y-coordinate for a control handle's anchor point in local coordinates. The anchor point is used for rubber-banding during dynamics.

## Syntax

    <YDyn>
    </YDyn>

## Attributes

Unit

Optional string. Represents a unit of measure. The default is DL. For details about DL, 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.

## Remarks

Rubber-banding allows the connector to be stretched as the shapes are moved. It improves the appearance of the drawing during shape movements.

The YDyn element is relevant only when contained in a Shape element. It is ignored when contained in a DocumentSheet, PageSheet, or StyleSheet element.
