Fiat-Tech has developed the structural design aid, which is called Innovative Structural Design Tool (iSDT) for home designers, engineers, architects and building contractors. It is called "innovative" since all the steps for designing from mid-size commercial structures to residential structures are greatly simplified. By creating beams, columns and foundations, all supporting systems and loading conditions are dynamically created from screen, and therefore modification can be quickly and easily made from the screen. All inputs and results are shown in one screen, which can greatly aid reviewing structural analysis.
