I know the gaps need packaging's answer. On my FR5 pattern, how do I include tool access too? Rotated product boxes have a preferred support direction.
Our empty-pallet demonstration missed exactly that neighbouring-carton problem, so I'd ask for the placement order on the same drawing rather than have two teams imagine different stages.
Give every position an identity and mark which are unsupported in the rotated layer. Packaging can answer for those loaded cases; tooling can answer for entry and exit at that stage. Someone still needs to own the combined decision if their proposed changes conflict.
Keeping the count is a preference, not a support finding. I would ask packing which alternatives they can tolerate before tooling spends time refining a pattern packaging may reject.
Then the meeting has a real decision to make. Ask packaging to identify which gap cases it can assess and what evidence is missing, and ask tooling to mark conflicts rather than silently move cartons to solve them.
