VerticalTextPosition Property (ActiveX)

Specifies the vertical position of text in relation to the dimension line.

Supported platforms: Windows only

Signature

VBA:

object.VerticalTextPosition

object

Type: Dim3PointAngular, DimAligned, DimAngular, DimArcLength, DimDiametric, Dimension, DimOrdinate, DimRadial, DimRadialLarge, DimRotated, Leader

The object this property applies to.

Property Value

Read-only: No

Type: acDimVerticalJustification enum

• acVertCentered: Centers the dimension text between the extension lines.
• acAbove: Places the dimension text above the dimension line except when the dimension line is not horizontal and text inside the extension lines is forced horizontal (DIMTIH = 1). The distance from the dimension line to the baseline of the lowest line of text is the current DIMGAP value.
• acUnder: Places the dimension text below the dimension line except when the dimension line is not horizontal and text inside the extension lines is forced horizontal (DIMTIH = 1). The distance from the dimension line to the baseline of the lowest line of text is the current DIMGAP value.
• acOutside: Places the dimension text on the side of the dimension line farthest from the defining points.
• acJIS: Places the dimension text to conform to Japanese Industrial Standards (JIS).

Remarks

The initial value for this property is acVertCentered.

Note: This property overrides the value of the DIMTAD system variable for the given dimension, leader, or tolerance object.

Examples

VBA:

Sub Example_VerticalTextPosition()
    ' This example creates an aligned dimension in model space
    ' and cycles the dimension text through a couple of different
    ' vertical alignments
    
    Dim dimObj As AcadDimAligned
    Dim point1(0 To 2) As Double, point2(0 To 2) As Double
    Dim location(0 To 2) As Double
    Dim CurrentValue As String
    
    ' Define the dimension
    point1(0) = 5: point1(1) = 5: point1(2) = 0
    point2(0) = 9: 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 text position
    Select Case dimObj.VerticalTextPosition
        Case acVertCentered:    CurrentValue = "centered"
        Case acAbove:           CurrentValue = "above"
        Case acOutside:         CurrentValue = "outside"
        Case acJIS:             CurrentValue = "to Japanesee industrial standards"
    End Select

    MsgBox "The vertical position of the dimension is: " & CurrentValue

    ' Change the position of the dimension text to be above the extesnion lines
    dimObj.VerticalTextPosition = acAbove
    ThisDrawing.Regen acAllViewports
    MsgBox "Dimension text is now aligned above extension lines"
   
    ' Change the position of the dimension text to be centered with the extension lines
    dimObj.VerticalTextPosition = acVertCentered
    ThisDrawing.Regen acAllViewports
    MsgBox "Dimension text is now centered with the extension lines"
