A package design system creates a package design file. The file includes comprises a two-dimensional representation of a three-dimensional structure having a plurality of facets having alternative design scenarios that can be selected based on conditions of the cutting and/or folding device that is used to create the package. An example of such a condition is a thickness of a substrate that is being processed by the device. The system creates the file by creating a set of cut and/or fold line definitions. At least one of the cut and/or fold line definitions will be a variable cut/fold line definition. For each identified variable cut/fold line definition, the system identifies one or more alternate parameters for the variable cut/fold line definition, a first cutting/folding scenario that will not use the alternate parameters, and a second cutting/folding scenario that will use the alternate parameters.
