Note
EXTCALL / EES
When calling a part program via EXTCALL without EES, the contour can only be called via
"Contour name" and/or "Labels". This is monitored in the cycle, which means that contour calls
via "subprogram" or "labels in subprogram" are only possible if EES is active.

programmed contour or in the opposite direction.
It is not imperative that the contour is closed. The following machining operations are possible:
● Inside or outside machining (on left or right of the contour).
