Linear Dimension

The Linear Dimension block provides a control to input an expression to the command whose dimensionality is always a linear distance length. As such, it is a special case of the Expression block.

Because the dimensionality is fixed, the Linear Dimension block does not expose the general-purpose Dimensionality property (or the associated HasUnitsMenu/Units properties) that the base Expression block has — it is pre-configured for linear length.

Block-specific properties

Property table structure mirrors the Expression block's property table (confirmed identical header/intro through BalloonTooltipText/BalloonTooltipImage), with Value/Formula/ExpressionObject/limit and increment properties present as in Expression, but scoped to linear-length semantics:

Property Name	Description	Access	Property Type	List of Values
BalloonTooltipText	Specifies text for the balloon tooltip.	CIGS	String	Any string value. Type \n for a line feed.
BalloonTooltipImage	Specifies the file name of the image displayed in the balloon tooltip.	CIGS	String	Valid bitmap file name from the NX library (no suffix/extension needed), or complete path. Supports TIFF, PNG, GIF, JPEG, BMP.
BalloonTooltipLayout	Location of text with respect to the image in the balloon tooltip (Horizontal/Vertical).	CIGS	Enum	Same as other blocks.
ExpressionObject	Specifies the Expression object tied to the block.	IG	TaggedObject	Object of type NXOpen.Expression.
Formula	Specifies the formula for the expression, e.g. sin(30).	CSG	String	Any string representing a valid formula.
Value	Specifies the expression's linear-distance value. Automation access returns the value in base part units (see Expression block notes on unit conversion).	CSG	Double	Any value.
LimitCheckTolerance / MaximumValue / MaxInclusive / MinimumValue / MinInclusive / PageIncrement / LineIncrement / AdaptiveScaleLimits / RetainValue / RetainUnits / WithScale	Same properties and semantics as documented on the Expression block page.	(various)	(various)	See Expression block.

Character	Stands for	Meaning
C	Creation	Modifiable interactively in Block UI Styler at design time.
I	Initialize	Modifiable at run time via NXOpen API, but only during the Initialize callback.
G	Get	Readable via NXOpen API in any callback.
S	Set	Modifiable at run time via NXOpen API in any callback.
