Useful Program Features
The Knowledge Base includes technical articles on a wide array of structural analysis and design topics.
These articles are intended to help you navigate through the Dlubal programs, learn efficient tips and tricks, and provide further insight into the program features.
Why Dlubal Software?
In RFEM and RSTAB, you can import DXF files via the import function. These DXF files can be used as the basis for modeling a structural system.
Until the program version of RFEM 5.06.1103, it was only possible to export the results on surfaces in the form of isolines into a DXF file. As of the program version 5.06.3039, it is now also possible to export the results in the Isobands display option.
The DXF interface in RFEM exports now a 3DFACE element in the DXF file for each FE mesh cell of the exported structure. The 3DFACE element is detected by AutoCAD during import, for example, and can be displayed as a surface in the graphic. Different visual styles help display the 3DFACE surfaces in a desired view.
RF‑CONCRETE Surfaces performs the ultimate and the serviceability limit state design of slabs, plates, folded plates and shells. In RFEM, the reinforcement resulting from this design can be displayed graphically on the surfaces of the structure using isolines. For the reinforcement design, it may be useful to export the results as isoline distribution in a DXF file in order to open them in a CAD application as background layers.
In RFEM, there is a file‑based and direct DXF interface. The file‑based DXF interface allows you to export the data in a DXF file that is transferred directly into an open AutoCAD file. In the interface dialog box, you can select which data are to be exported (results as isolines, result values, finite element mesh with boundary and integration lines).
