This Inkscape extension draws carton containers intended for plotter or dieline cutting and creasing. This is release one; thus, it is a proof of concept that developed while exploring the potential of Inkscape's extensions framework. In this version, under Job Settings --> General --> Drawing Diagnostic, I have implemented an experiment titled. "Closure." This allows one to see what the clip lock lid design would look like when assembled as opposed to being flat. I later intend to use this same feature to tidy up the trash-lock base, to make sure it holds together when assembled. Then it will be a real crash-lock, not a quick and dirty imitation trash-lock.
