StructureCollectionInitialize Method

Initialize structure collection. Use only when no boundary and cross section data is available, typically when the structure module is used independently (not part of network simulation)

Collects structures with identical location in composite structures.

This automatically calls [!:IStructure.Initialize(IBoundaryData, CrossSectionData,bool,IDiagnostics)] on each structure in the collection, setting the IsLinkStructure to true (no cross sectino data available)

Initialize structure collection

Collects structures with identical location in composite structures.

This does not call [!:IStructure.Initialize(IBoundaryData, CrossSectionData,bool,IDiagnostics)]. You need also to call initialize on each structure individually.
