The add-on module RX-LINK extends the options to import data in RFEM. After the successful installation, the following additional interfaces are available:

• Standard Acis Text Format (*.sat)
• Initial Graphics Exchange Specification (*.igs, *.iges)
• Standard for the Exchange of Product Model Data (*.stp, *.step)

These data formats make it possible to import the geometry of the model as boundary lines, surfaces and solids. The models can be imported either as RFEM objects (nodes, lines, surfaces, solids) or as background layers so that the nodes can be set manually. The quality of the imported model depends on the original program. The import is carried out via files exclusively. Those formats are used mainly in the area of mechanical engineering.
