Meaning
CTABTSV: Read following axis value at the start of curve table no. <n>
CTABTEV: Read following axis value at the end of curve table no. <n>
CTABTSP: Read leading axis value at the start of curve table no. <n>
CTABTEP: Read leading axis value at the end of curve table no. <n>
CTABSSV: Read following axis value at the start of the curve segment belonging to the
specified leading axis value (<master value>)
CTABSEV: Read following axis value at the end of the curve segment belonging to the
specified leading axis value (<master value>)
CTAB: Read following axis value for specified leading axis value (<master
value>)
CTABINV: Read leading axis value for specified following axis value (<following
value>)
CTABTMIN: Define following axis minimum value:
● In the entire definition range of the curve table
or
● In a defined interval <a> ... <b>
CTABTMAX: Define following axis maximum value:
● In the entire definition range of the curve table
or
● In a defined interval <a> ... <b>
<n>: Number (ID) of curve table
<gradient>: The <gradient> parameter returns the incline of the curve table function
at the calculated position.
