For Level 1 (and further levels) there will be multiple elements, representing the architecture for that particular level of decomposition. For each of these there will be a package, under which will be an element, such as class (or possibly a block if using SysML) and a context diagram for that element. There is a Building Block template for this structure under the Logical Elements folder starting at Level 1. This is shown in Figure
