ExtLine1EndPoint Property (ActiveX)

Specifies the endpoint of the first extension line.

Supported platforms: Windows only

Signature

VBA:

object.ExtLine1EndPoint

object

Type: Dim3PointAngular, DimAngular

The objects this property applies to.

Property Value

Read-only: No

Type: Variant (three-element array of doubles)

A 3D coordinate representing the endpoint of the first extension line.

Remarks

The ExtLine1EndPoint and ExtLine2EndPoint properties contain the endpoints of the extension lines. If no extension lines exist for a given dimension, these points will equal ExtLine1StartPoint and ExtLine2StartPoint.

Examples

VBA:

Sub Example_ExtLine1EndPoint()
    ' This example creates an angular dimension. It then changes
    ' the location of the ExtLine1EndPoint.
    
    Dim dimObj As AcadDimAngular
    Dim angVert(0 To 2) As Double
    Dim FirstPoint(0 To 2) As Double
    Dim SecondPoint(0 To 2) As Double
    Dim TextPoint(0 To 2) As Double

    TextPoint(0) = 3#: TextPoint(1) = 5#: TextPoint(2) = 0#
    
    ' Create the angular dimension in model space

    ' Change the endpoint of the first extension line
    SecondPoint(0) = 0: SecondPoint(1) = 3: SecondPoint(2) = 0
    dimObj.ExtLine1EndPoint = SecondPoint
    dimObj.Update

    ' Note that the return value is a Variant
    Dim retPnt As Variant
