I have an assembly with multiple sub assemblies and sheet metal parts at various levels of the main assembly.

Currently in order to update the flat pattern bounding box dimensions, when I do a dimensional change to the folded part, I need to unfold and fold the part to get the bounding box dimensions to update.

I guess first of all, is there a way to have this sort of thing update automatically?

Second, if I can't get it to work automatically, is there a macro that would be able to identify each sheet metal part in an assembly and do that unfold-fold procedure for me?
