Specifies the distance between the dimension text and the dimension line when you break the dimension line to accommodate dimension text.
Supported platforms: Windows only
VBA:
object.TextGap
Type: Dim3PointAngular, DimAligned, DimAngular, DimArcLength, DimDiametric, Dimension, DimOrdinate, DimRadial, DimRadialLarge, DimRotated, Leader
The objects this property applies to.
Read-only: No
Type: Double
A real number specifying the gap distance.
This property also sets the gap between the annotation and a hook line on a Leader object.
A negative value creates basic dimensioning (dimension text with a box around the text).
VBA:
Sub Example_TextGap()
   ' This example creates an aligned dimension in model space and
   ' uses the TextGap property to increase the distance between the
   ' dimension line and 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
    ' Read and display current dimension gap
    MsgBox "The dimension gap for this object is currently set to: " & dimObj.TextGap
    ' Increase the distance of the dimension gap
    dimObj.TextGap = 0.5
    ThisDrawing.Regen acAllViewports
    
    ' Read and display current dimension gap
    MsgBox "The dimension gap for this object is now set to: " & dimObj.TextGap
    
End Sub
