Hello Alejandro,
Thanks for your question.
To subtract layers in FAB 3000 use composites (menu: Tools / Composites / Build Composite...). Here's more information, https://support.numericalinnovations.com/support/discussions/topics/14000014877
Thanks again.

The function can be found in the following path:
Tools -> Boolean Wizards -> Subtract
Could this be solved?
Thanks in advance
