object.TextHeight
Type: Dim3PointAngular, DimAligned, DimAngular, DimArcLength, DimDiametric, Dimension, DimOrdinate, DimRadial, DimRadialLarge, DimRotated, MLeader, MLeaderStyle, Tolerance
The objects this property applies to.
Read-only: No
Type: Double
The height for the dimension text.
The initial value for this property is 0.1800.
If the current text style has a fixed text height, this property is ignored.
VBA:
Sub Example_TextHeight()
    ' This example creates an aligned dimension in model space and
    ' uses the TextHeight property to increase the height of the
    ' dimension text
    Dim dimObj As AcadDimAligned
    Dim point1(0 To 2) As Double, point2(0 To 2) As Double
    Dim location(0 To 2) As Double
    
    ' Define the dimension
    point1(0) = 5: point1(1) = 5: point1(2) = 0
    point2(0) = 5.5: point2(1) = 5: point2(2) = 0
    location(0) = 5: location(1) = 7: location(2) = 0
    
    ' Create an aligned dimension object in model space
    Set dimObj = ThisDrawing.ModelSpace.AddDimAligned(point1, point2, location)
    ThisDrawing.Application.ZoomAll
