Jona,
I haven't tested but our CAM operator is telling me our Per DOES go to the table and the wrapper to the coil line.
On the other hand, liner is going to the waterjet not running the liner on the coil on DW. And all liner is calculated to the INSIDE of the Perf not the wrapper regardless of settings, so we typically have to make a copy of all fittings or change the existing ones to change to liner only from DW after nesting the perf so we can then nest the liner and have it developed properly.
May want to reach out directly to Martin Schmid...he's dug in pretty deep on the DW issues we've sent to him. Might get a change of getting it fixed in the next decade that way. ;-)
