Specifies the origin of extension line 1.
Supported platforms: Windows only
VBA:
object.ExtLine1Point
Type: DimAligned, DimArcLength
The objects this property applies to.
Read-only: No
Type: Variant (three-element array of doubles)
A 3D coordinate representing the origin of the first extension line.
The dimension line of an aligned dimension will be parallel to the line joining the origins of extension lines 1 and 2.
Line to be dimensioned
