iTWO structure fem supports versatile options for a direct data transfer to other CAD systems by passing on design information (Allplan, STRAKON, etc.) In addition, software components installed by manufacturers (Schöck, Halfen, Filigran, etc.) can be directly accessed from the program environment and supplied with result data from the FE system. Thus iTWO structure fem becomes an overall interconnected program system.

The IFC interface for the ZEICON engineering CAD system supports the data exchange from digital building models in civil engineering via IFC files (Open BIM), which contain component information in an open standard. When importing or exporting (from V20 on) the IFC data, a direct assignment to the components known in ZEICON is made from the geometry description. On the basis of the existing model information, the design drawings for the components can be created after the calculation and dimensioning of the structure.
