2*PI added to it to convert it to its positive equivalent.
The obliquing angle determines the forward or backward slant of the text. The angle represents the offset from its vertical axis (90 degrees). To set the obliquing angle, use the ObliqueAngle property. The obliquing angle must be provided in radians. A positive angle denotes a lean to the right, a negative value will haveThis example creates a Text object then slants the text 45 degrees.
Sub Ch4_ObliqueText()
Dim textObj As AcadText
Dim textString As String
Dim insertionPoint(0 To 2) As Double
Dim height As Double
' Define the 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)
' Change the value of the ObliqueAngle
' to 45 degrees (.707 radians)
textObj.ObliqueAngle = 0.707
textObj.Update
