Integration in Tekla Structures
When planning a building or a construction, there are usually different individual models used for CAD and structural analysis. On one hand, these models may cause planning and transfer errors, and on the other hand, they require double effort.
Integrated interfaces between RFEM/RSTAB and Tekla Structures, which also uses the 64‑bit operating system, prevent such problems. The direct connection between CAD and structural analysis ensures efficient and reliable planning.
Export to RFEM/RSTAB
Using the direct interface integrated in programs by Dlubal Software, you can easily transfer the analytical model of detailed structural systems from Tekla Structures to RFEM/RSTAB.
Analytical Model in Tekla Structures
A analytical model is automatically generated when designing the structure in Tekla Structures. This model can be exported to RFEM/RSTAB by clicking the corresponding button. Information about supports, releases, and loads that may be contained in the Tekla model is transferred as well. After the export, the structure is designed in the usual environment of RFEM/RSTAB. The analytical model is identical to the model manually created in RFEM/RSTAB.
Smart Design Objects
The data exchange keeps the 'intelligence' of the objects: It means a column or a beam is replaced by a similar object in RFEM, not only by a group of lines.
Once the structure and cross-sections has been calculated and designed, it is possible to retrieve the cross-section modifications from Tekla Structures in an analytical model and align them using a clear allocation of structural components. Moreover, the program checks if members have been removed or added. Connections entered in Tekla Structures are adjusted directly and automatically. New connections can be designed on the basis of the imported member end results.
In order to extend the options of the data exchange using the DSTV-STP files, it is possible to transfer the physical model from RFEM/RSTAB to Tekla Structures and vice versa.
Export to Tekla Structures
A model calculated and designed in RFEM/RSTAB can be exported directly to Tekla Structures, for example for detailing reasons.
Since columns and beams are often divided into individual connection nodes in structural analysis while the real member is made of "one piece", it is possible to define sets of members in order to create columns and beams in Tekla Structures. For a better overview, comments concerning the members and sets of members in RFEM/RSTAB can be written in the "Name" text box of Tekla Structures. Object properties (concerning nodes, for example) remain preserved in Tekla Structures as well.
Updating the Model
In the case of changes in structural planning, it is possible to use the direct interface to promptly update the Tekla model by adjusting the modified materials, coordinates, and cross-sections. Then you can remove the design elements that are no longer available and add new ones.
Import from Tekla Structures
In addition to the analytical model, the interface enables direct import of the physical model from Tekla Structures to RFEM/RSTAB.

The direct interface with Revit allows you to update the Revit model according to the changes you have made in RFEM or RSTAB. Depending on the modification, the Revit objects may have to be regenerated (deleting the object and subsequent regeneration). The regeneration is performed on the basis of the RFEM/RSTAB model.
If you want to avoid this regeneration, activate the option "Update only materials, thicknesses, and sections." In this case, only the properties of the objects will be adjusted. Changes different from those in material, surface thickness, and section are, however, not considered in this case.
