You can prepare the flattening process by choosing how to flatten the branches in the geometry. The Flatten Status command enables you to check and modify the flatten status of a branch based on its flatten status attribute.
This command is useful especially for internal branches of complex connectors because it does not make sense to have them flattened. The selected devices must belong to the same electrical geometry.
A complex device assembly is a set of devices linked to the end of a branch route through the segment connection point or the cavity. This set can have several layers or levels starting from the branch end till the equipment connector.
