<p><font face="MS Sans Serif,Arial" size=2>If group 72 and/or 74 values are nonzero then the first alignment point values are ignored and AutoCAD calculates new values based on the second alignment point and the length and height of the text string itself (after applying the text style). If the 72 and 74 values are zero or missing, then the second alignment point is meaningless.
