You can justify line text horizontally and vertically. Left alignment is the default. To set the horizontal and vertical alignment options, use the Alignment property.
This example creates a Text object and a Point object. The Point object is set to the text alignment point, and is changed to a red crosshair so that it is visible. The text alignment is changed and a message box is displayed so that the macro execution is halted. This allows you to see the impact of changing the text alignment.
Dim textObj As AcadText
Dim textString As String
Dim insertionPoint(0 To 2) As Double
Dim height As Double
' Define the new Text object
textString = "Hello, World."
insertionPoint(0) = 3
insertionPoint(1) = 3
insertionPoint(2) = 0
height = 0.5
' Create the Text object in model space
Set textObj = ThisDrawing.ModelSpace. _
AddText(textString, insertionPoint, height)
' Create a point over the text alignment point,
' so we can better visualize the alignment process
Dim pointObj As AcadPoint
Dim alignmentPoint(0 To 2) As Double
alignmentPoint(0) = 3
alignmentPoint(1) = 3
alignmentPoint(2) = 0
Set pointObj = ThisDrawing.ModelSpace. _
pointObj.Color = acRed
' Set the point style to crosshair
ThisDrawing.SetVariable "PDMODE", 2
' Align the text to the Left
textObj.Alignment = acAlignmentLeft
MsgBox "The Text object is now aligned left"
' Align the text to the Center
textObj.Alignment = acAlignmentCenter
' Align the text to the point (necessary for
' all but left aligned text.)
textObj.TextAlignmentPoint = alignmentPoint
MsgBox "The Text object is now centered"
' Align the text to the Right
textObj.Alignment = acAlignmentRight
MsgBox "The Text object is now aligned right"
