VBA:

object.ExtLine2Point

object

Type: DimAligned, DimArcLength

The objects this property applies to.

Property Value

Read-only: No

Type: Variant (three-element array of doubles)

Remarks

The dimension line of an aligned dimension will be parallel to the origins of extension lines 1 and 2.

Line to be dimensioned

Dimension created

Examples

VBA:

Sub Example_ExtLine2Point()
    ' This example creates an aligned dimension and then changes the
    ' ExtLine2Point property for that dimension.

    location(0) = 5#: location(1) = 7#: location(2) = 0#
    
    ' Create an aligned dimension object in model space
