IDimensionStyleText Interface

Provides access to members that control a dimension style's text.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

The IDimensionStyleText interface contains properties that control how the text of a dimension feature is displayed.

Members

	Name	Description
	Align	Indicates if the text should be aligned with the dimension line.
	ConvertUnits	Indicates if the length of the dimension needs to be converted for display.
	DisplayPrecision	Precision for the value displayed by the dimension text.
	DisplayUnits	Units the length of the dimension text is displayed in.
	Expression	Text expression for the style.
	ExpressionParserName	Text expression parser for the text expression for the style.
	ExpressionSimple	Indicates if the text expression is simple or custom for the style.
	ExtendLineOnFit	Indicates if the dimension line will be extended to underline the text on inward dimensions.
	Prefix	Prefix for the text expression for the style.
	Suffix	Suffix for the text expression for the style.
	TextDisplay	Text display setting for the style.

Classes that implement IDimensionStyleText

Classes	Description
DimensionStyle	A container of properties which dictate how a dimension feature is displayed.

Remarks

The Align property will force the text to align to the angle of the DimensionLine. If the Align property is False, the TextSymbol�s angle will be used. The ConvertUnits property specifies if the value of the text will be converted from the feature class�s native units to the units of the DisplayUnits property. The text can be formatted using the DisplayPrecision property and the TextDisplay property. The esriDimensionTextDisplay enumeration defines four values for formatting the text string:

esriDimensionTDValueOnly - Displays only the numeric value.
esriDimensionTDPrefixSuffix - Displays the numeric value with the Prefix and Suffix property.
esriDimensionTDExpression - Evaluate the numeric value in the code expression.
esriDimensionTDNone - Do not display text.

The text string can also be determined from an expression specified in the Expression property. The expression can be a simple concatenation of column values and strings or a function written in scripting language. The name of the parser for the expression should be specified in the ExpressionParserName property. The currently available parsers are "VBScript", "JScript", and "Python".

The TextFit property determines where the text will be placed if it does not fit between the markers after they have been moved (due to marker fit settings). The esriDimensionTextFit enumeration defines three values for this behavior:

esriDimensionTextFitNone - Do not move text.
esriDimensionTextFitMoveBegin - Move text to beginning dimension line.
esriDimensionTextFitMoveEnd - Move text to ending dimension line.

When the markers are moved because of a fit, a line will be drawn between the markers based on the DrawLineOnFit property.
