Cross sections can be plugged directly into the components for creating elements (“LineToBeam”, “MeshToShell”, …). Alternatively when fed into an “Assemble”-component (see fig. 3.3.1) they act on the elements whose identifiers match the string given via “Elem|Id”. In case an element is provided at the “Elem|Id”-input, its identifier is used for attaching the cross section to elements. A cross section added via the “Assemble”-component overrides a cross section provided directly at an element-creation-component.
