To analyse large structures using traditional solutions like Inventor Nastran one has to think about idealising the structure into simpler forms. Typically, this involves analysing the structure as beam (line) elements, shell (surface) elements or a combination of both. By doing this the structure is considerably simplified which may also include excluding components that may deem to be structurally insignificant. All this leads to additional time in preparing a model suitable for analysis. SimSolid on the other hand excels in analysing large structures without the need to simplify.
