Specifies the distance the extension lines are offset from the origin points.

Supported platforms: Windows only

Signature

VBA:

object.ExtensionLineOffset

object

Type: Dim3PointAngular, DimAligned, DimAngular, DimArcLength, DimDiametric, DimOrdinate, DimRotated

The objects this property applies to.

Property Value

Read-only: No

Type: Double

A positive real number specifying the distance to offset the extension line beyond the origin points.

Remarks

The initial value for this property is 0.0625.

Note: This property overrides the value of the DIMEXO system variable for the given dimension.

Examples

VBA:

Sub Example_ExtensionLineOffset()
    ' This example creates a Dim3PointAngular object in model space
    ' and changes the offset of the extension lines using the
    ' ExtensionLineOffset property
    
    Dim DimPointAngularObj As AcadDim3PointAngular
    Dim AngleVertex(0 To 2) As Double
    Dim FirstPoint(0 To 2) As Double, SecondPoint(0 To 2) As Double
    Dim TextPoint(0 To 2) As Double
    
    ' Define the new Dim3PointAngular object
    AngleVertex(0) = 0: AngleVertex(1) = 0: AngleVertex(2) = 0
    FirstPoint(0) = 2: FirstPoint(1) = 2: FirstPoint(2) = 0
    SecondPoint(0) = 1: SecondPoint(1) = 4: SecondPoint(2) = 0
    TextPoint(0) = 6: TextPoint(1) = 6: TextPoint(2) = 0

    ' Create the new Dim3PointAngular object in model space
    Set DimPointAngularObj = ThisDrawing.ModelSpace.AddDim3PointAngular(AngleVertex, FirstPoint, SecondPoint, TextPoint)
    ThisDrawing.Application.ZoomAll

    ' Read and display current offset of the extension lines from the control points
    MsgBox "The extension lines are currently offset " & DimPointAngularObj.ExtensionLineOffset & " units"

    ' Change the extension lines offset distance from the control points
    DimPointAngularObj.ExtensionLineOffset = 1.5
    ThisDrawing.Regen acAllViewports
    
    ' Read and display current offset of the extension lines from the control points
    MsgBox "The extension lines are now offset " & DimPointAngularObj.ExtensionLineOffset & " units"
    
End Sub
