Exporting Data from RFEM 6/RSTAB 9 to AutoCAD/DXF Files
Exporting data from RFEM 6/RSTAB 9 to AutoCAD/DXF files is a valuable feature that facilitates data exchange, improving workflow efficiency and enabling further refinement of design outputs. The export process is initiated by navigating to the "File" menu and selecting the "Export" option, similar to the import process described in KB 1941 linked above. The "Export" window that appears (see Image 1) closely resembles the "Import" window, with the core features being largely the same. Since these features have been covered in detail in the aforementioned article, this section will focus on the specific export options available in RFEM 6 and RSTAB 9, highlighting the unique features that ensure efficient data transfer to AutoCAD/DXF files.
Export Dimensions
This option ensures that dimensions are included when exporting an RFEM/RSTAB model to a DXF file, facilitating accurate representation of measurements within the AutoCAD environment.
Export FE Mesh
By selecting this option, the finite element (FE) mesh is included in the DXF export, with the mesh's boundary lines represented as individual lines, preserving the structural details of the model.
Export FE Mesh as 3DFace
RFEM 6 allows the export of 3D face elements (3DFACE) corresponding to each FE mesh cell, which AutoCAD recognizes and displays as surfaces, improving the visual accuracy of the FE mesh.
Deformed Shape
The deformed shape for the active load case (LC) and load combination (CO) is exported as lines, providing a simple representation of the model's deformation under applied loads.
Export Deformed Shape as 3DFace
The deformed shape under the active load case (LC) and load combination (CO) is exported as 3DFace elements, offering a more detailed and visually informative representation of the deformed model.
Conclusion
In this article, we have explored the export features from RFEM 6 and RSTAB 9 to AutoCAD/DXF files, highlighting the essential options available for seamless data exchange. By utilizing these features—such as exporting dimensions, FE meshes, and deformed shapes—you can ensure that your structural models are accurately transferred and represented within AutoCAD. Whether you need a simple line representation or a detailed surface depiction of the model’s deformation, RFEM 6 and RSTAB 9 provide the flexibility to meet various export requirements. These options enhance workflow efficiency while improving the clarity and precision of your design outputs.
