The ConvertToArtistic method changes paragraph text to artistic text.
Examples:
The following VBA example converts all paragraph-text objects to curves by converting them to artistic text first.
Sub Test()
Dim s As Shape
For Each s In ActivePage.FindShapes(, cdrTextShape)
If s.Text.Type = cdrParagraphText Then
s.Text.ConvertToArtistic
s.ConvertToCurves
End If
Next s
End Sub
