Answer:
RFEM includes an interface to the Dlubal programs. Input data of all previous versions of RFEM can be imported without problems. You can also open the files of the structural frame and truss analysis software RSTAB directly and complete them with surface/solid elements. On the other hand, you can also open the files created in RFEM 5 in RSTAB 8.
There is a direct link to the CAD applications of Tekla Structures and AutoCAD (but not for LT versions). With RFEM, you can use the advantages of BIM (Building Information Modeling) to exchange data models for digital planning.
