Specifies the Z-distance from the largest inlet or outlet nozzle to the current nozzle. Type a positive value if the nozzle Z-coordinate is greater than that of the largest nozzle, that is, if the nozzle is farther out on the positive Z-axis.
Typical units (depending on your unit system):
-
in
-
mm
-
cm
If the current nozzle is the largest inlet or outlet nozzle, then the value is 0.
