Wait til you start optimizing for CNC when your logic is full lenght X/Y axis rips only and your no longer constrained by that method and parts can be tucked in small notches and waste areas. At that point the answer is that the software has it correct lol. Ive sat with guys who want to make you turn this part and try to fit that part over there and wont that fit in that little waste piece and after two or three iterations I tell them we are going to lawyer style billing and every minute of shifting parts is $5. But no matter how often I take the time for the heck of it to re-orient the parts in the manner "they would have cut the sheet" and show them that they would have spread into an extra sheet or two, they dont get it. They would twist a part around or say oh that one part the grain orientation doesnt matter so Id have rotated, and so on. I go through this regularly cutting parts for others.
A big part is coming to the realization that giving things over to the software will usually mean seeing a bunch of things where you think your smarter than the software and the software is wrong, but when you look at your balance sheet at the end of a project you'll see that your waste material in the dumpster is less. It lays them out as best it can calculate mathematically based on yeild and has no ability to allow for the fact that you may like or want your drops from job "A" on the Y axis of the sheet but on this job B-2.0 you want them on the X axis.
No cutlist optimization tool will lay things out "the way you would" (they lay them out better than that lol).
