TextPrefix Example

Using Programming Languages other than VBA

Sub Example_TextPrefix()
   ' This example creates an aligned dimension in model space and
   ' uses TextPrefix to allow the user to change the text prefix for the
   ' dimension

	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 prefix As String

	' Define the dimension
	point1(0) = 0: point1(1) = 5: point1(2) = 0
	point2(0) = 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

	' Allow the user to change the text prefix for the dimension
	prefix = InputBox("Enter a new text prefix for the dimension", "Set Dimension Prefix", "PREFIX:")
	dimObj.TextPrefix = prefix   ' Commit changes to prefix

	ThisDrawing.Regen acAllViewports

	' Read back and display the dimension text prefix
	prefix = dimObj.TextPrefix
	If prefix <> "" Then
		MsgBox "The prefix of the dimension has been changed to: " & prefix
	Else
		MsgBox "The prefix of the dimension has been removed"
	End If
End Sub
