Multizone Stackups and Rigid-Flex Bends
Creating a multizone stackup allows a design to be divided into areas called zones. Each zone contains a subset of layers available to the entire circuit board and is spatially defined by polygons on the Outline layer.
When an object (e.g., a primitive) is placed on a layer, it is also placed in a zone. Objects belong to the zone where their center point resides, even if part of the object is in another zone. Likewise, terminals and ports also belong to the zone in which they reside. If an object with terminals is placed over a zone boundary, the terminals are automatically assigned to the zone they are in. Those terminals may only be placed on the layers available in their zone. If a zone boundary changes, the zone placements of all terminals, padstacks, and objects are automatically recomputed. Objects in a zone may only be placed on layers in that zone (e.g., if a voltage source is placed over multiple zones, its individual terminals are assigned to the zones in which they are located).
You cannot remove a layer from a zone if there are objects on that layer and in that zone.
Follow the steps in each subsection to define a multizone stackup and add rigid-flex bends to a design model.
