methodologies for representing the stackup structure and the stackup to zone reference, the Chart and
the Table.
The Chart process creates a graphical representation of each of the stackup definitions in the design.
Graphical chart is a group of geometries placed into a fabrication drawing. The chart describes the
stackup structure as defined in Cross Section Editor, a note for each graphical image listed may need to
be added to identify the zones with which each chart is associated.

The Table process displays a spreadsheet into the drawing database that is a close representation of the
Cross Section Editor form. The materials, thicknesses, tolerances, and other attributes are listed. Most
importantly, the zones that are associated with the stackup are listed in the table.
