FAB 3000 has 3 requirements to accept a border layer.
I'm following all these rules and it's still not working. I need a border to convert to a negative layer, it is not working.
If you're having a specific problem, please just submit a support ticket, https://support.numericalinnovations.com/support/tickets/new
Note: If possible attach a sample workspace file (*,wrk) - so we can create a tutorial movie showing you specifically what steps to perform.
* Boarders must be drawn with an actual aperture (Dcode). Boarders drawn as a line will not work even with automatic boarder creation.
See attached video.

Even though there is a boarder already created FAB does not recognize it and wants to create a new one. At times it will automatically create a new boarder, sometimes it wants to do it selectively.
