i am finding that the optimatision settings are applied globally and are applied for all sheet material types and are not customisable for each sheet material type.
i find that this is affecting the optimatization in the no of sheets required, also in the offcut size produced as well. a optimisation will produce a nice perfect fit for one sheet material type but another sheet type will be quite bad.
further i noticed and with each change to the optimisation settings ALL sheet layouts are regenerated and if there is a particular set of mappings preferred, it is then lost on re - optimatzation. perhaps a feature to put a lock and a preferred sheet type layout map so its not regenerated on the next optimatization. also i find that i cannot do a re-optimise for just a particular/individual sheet type.
