An insert represents the inclusion of one job as a part of the contents of another. The job containing the insert is the parent job, and the job that is included is the master job of the insert. Inserts can create hierarchical designs. The master of an insert can contain instances of other masters. This hierarchy can continue for as many levels as needed to express a complete design.
Inserts make it easy for the user to combine and visualize the placements of different jobs resulting in optimum configurations (like pieces of a puzzle) which will save you time & money on manufacturing. Inserts can be transformed (ie. rotate, mirror, move, etc) and can be nested into a hierarchy of jobs/panels.
