Abstract: A package generation system creates a package definition file for creation of a package flat. The file includes dimensions for cut lines along which the package will be separated from a two dimensional substrate. The flat includes facets and functional elements that connect the facets. The system will identify a pair of the functional elements that have a connecting relationship. The first facet of the pair is a tab structure having a symmetric design, and the second facet of the pair is a receiving structure. If the tab structure and receiving structure are connected to cut lines that intersect at a pivot point, the system will convert the definition of the tab structure from the symmetric design to a non-symmetric design. It will save dimensions for the edges and functional elements in the package design file with the non-symmetric design.
