The thick metal can extend upward through the dielectric layer from the level on which the polygon is drawn, or downward into the dielectric layer below. If the thick metal is not as thick as the dielectric layer, then the polygon only appears on the level where it was drawn. If the thick metal is the same thickness or thicker than the dielectric layer it appears on both the metal level where it was drawn and on the next metal level. Some examples of the project editor view are provided below.
