Determines the lead‐
ing axis position at the
end of the curve table.
Determines the mini‐
mum value of the fol‐
lowing axis in the en‐
tire definition range of
the curve table or in a
defined interval
Determines the maxi‐
mum value of the fol‐
lowing axis in the en‐
tire definition range of
the curve table or in a
defined interval
