This calculation has five methods:
ANGLE
XPLUS
XMINUS
YPLUS
YMINUS
Use this calculation to define three EXTREME calculations for a blade. Currently, this calculation finds the extreme of a section along any of the four axes. It does this with the actual without any fit applied.
The sign of the calculation is purely arithmetical. If you are planning to find the extreme XMINUS or YMINUS point and expect to see a positive number when the actual "sticks out beyond" the nominal, you need to use a multiplier of -1.
