When building a cab in Polyboard, do you set up the board selection here for grained board, and then transfer to OptiNest? Or do you create cabs in Polyboard and tell OptiNest board is grained later?

I have processed only a hand full of jobs so far with what is new software to me, and this is my first grained job. I have all sorts of panels in OptiNest i would running the right way the grain.

Cheers
