We are using the Legacy optimizer yet and I am wondering if that is the reason these plywood diewall plates "allegedly" don't fit on a 4x8 sheet with sheet grain length turned on in the material file, part grain turned off. My guess is that if I turn it off for the sheet, they would nest fine. I don't want to try that yet though. They should nest perfectly regardless and they do not.  Also, this is in an extruded diewall product I built from scratch.
