Anthony, would you please confirm the AFXTAB and AFYTAB data, in particular, the last 6 points, in each array, as follows:

"X & Y" Elements 24: Leading Edge "tangent" point, end of arc radius, and also the starting control point, of the curve "spline".
"X & Y" Elements 25: Trailing Edge "tangent" point, end of arc radius, and also the ending control point, of the curve "spline".
"X & Y" Elements 26: Leading Edge "uppermost arc radius start" point.
"X & Y" Elements 27: Leading Edge "arc radius center" point.
"X & Y" Elements 28: Trailing Edge "lowermost arc radius start" point.
"X & Y" Elements 29: Trailing Edge "arc radius center" point.

I will enter the first and last points of the "spline", again, (a second time, in the order to be selected for spline), to simplify point selection in the for loop.
