Dlubal Structural Analysis Software and BIM
Dlubal Software has set a goal to allow you to plan according to BIM. And this mission was undoubtedly successful! Due to the numerous interfaces in the structural analysis programs RFEM and RSTAB, you can easily and conveniently exchange data with the common industry software (such as CAD programs).
RFEM and RSTAB do not clash with other software – on the contrary. There are interfaces to many other programs and some of them are introduced in the following.
Webservice and API
Technology takes you further, also in your daily work with RFEM / RSTAB. The new API technology Webservice allows you to create your own desktop or web-based applications by controlling all objects included in RFEM 6 / RSTAB 9. Entire libraries and numerous functions are available to you. Thus, you can easily perform your own design checks, effective modeling of parametric structures, and optimization and automation processes using the programming languages Python and C#. Dlubal Software makes your work easier and more convenient. Check it out now!
Integration in Autodesk Revit
Do you enjoy working with Autodesk Revit and wish there was an interface to the Dlubal Software? Then your wish has already become a reality! The direct bidirectional interface in RFEM 6 / RSTAB 9 to Autodesk Revit makes it easy for you: A structure created in RFEM/RSTAB can be visualized in Revit and prepared for the design engineer. In the same way, it is possible to calculate and design a Revit model in RFEM/RSTAB. You can even easily align the subsequent modifications in both the Revit and the RFEM/RSTAB model. Does that sound like a dream? Then live it and read more at:
Interface to TEKLA Structures
Dlubal Software also has interfaces with the BIM software Tekla, so you can easily exchange data. There are three options available between RFEM 5 / RSTAB 8 and Tekla Structures: Frame models can be transferred based on files in both directions via the stp interface. An analysis model generated and carried out in Tekla Structures can be transferred to RFEM/RSTAB via a direct interface. Furthermore, physical models can be exchanged and aligned in both directions via another direct interface. Dlubal Software makes your work easier.
Integration in Autodesk AutoCAD
You may already be familiar with data exchange using DXF. Moreover, RFEM 5 / RSTAB 8 supports direct exchange with AutoCAD by Autodesk. Does that sound too good to be true? In fact, it is reality. This interface uses the latest .NET technology. Furthermore, you can start the data exchange directly in RFEM/RSTAB. The rest runs itself.
RFEM 6 Interface to Nemetschek Allplan (*.asf)
ASF files allow you to export the reinforcement determined in the Concrete Design add-on for RFEM 6. You can then display them in the Allplan program as reinforcement contours and FEA reinforcement color images.
But that's not all. Furthermore, the company Allbau Software GmbH provides an Allplan2Dlubal plugin, which is used to automatically generate a plate-member model from the Allplan model for use in Dlubal structural analysis software. After all, cooperation makes everything better and facilitates your daily work as a user.
RFEM 6 Interfaces to Rhino & Grasshopper
Rhinos are considered stubborn and inflexible. Rhino is clearly the exception. The bidirectional interface RFEM 6 - Rhino allows you to transfer various line types as well as surfaces (plane, rotated surface, and NURBS).
Also the bidirectional Grasshopper interface allows you to export and import model data, load cases and combinations, and the loads themselves. Instead of volatility, you will find a stable connection that you cannot build on, but that allows you to plan ahead.
SAF Interface
Dlubal Software has also interfaces with open source software, such as SAF. This will make your work much easier. RFEM 6 and RSTAB 9 support the data exchange using the Structural Analysis Format (SAF). The structural analysis programs offer you both import and export. SAF is based on MS Excel. It is a file format intended to facilitate the exchange of structural analysis models between different software applications. We can assure you: It is definitely an asset to any structural engineer.
Data Exchange with Dietrich's (*.ifc)
Cooperation is the key to success in this industry. With the IFC interface and the "CAD/BIM Model", you can import IFC files as well as convert them to member and surface elements. This import has been optimized in cooperation with the company Dietrich's so that the corresponding cross-sections and materials are assigned automatically for member elements. Enjoy structural analysis together!
Interface to SketchUp with the 3skeng Steelwork Tool
With the program 3skeng Steelwork in SktechUp, it is possible to export IFC files based on "Structural Analysis View". This view contains the structural system with member hinges and cross-section as well as material properties.Use "File" → "Import" to import the IFC file. For more detailed information, see the SHK Engineering and Consulting GmbH & Co. KG website.
Product Interface for Steel Structures (*.stp)
Would you like to be able to finally transfer member structures a step further in your project? We have something for you! The DSTV product interface for steel structures has been implemented for transferring pure member structures. This allows you to exchange data between RFEM 5 / RSTAB 8 and the programs like "Bentley ProStructure 3D", "Tekla Structures", "Bocad", "Intergraph Frameworks", "Graitec Advance Steel", "Cadwork", and many others. Together, everything moves forward more easily.
Microsoft Excel
MS Excel is a classic when it comes to the further processing or preparation of table values. We have implemented a direct link to Microsoft Excel for you in RFEM 6 / RSTAB 9. Thus, you can export the tables of RFEM 6 / RSTAB 9 individually or all at once, directly into an Excel spreadsheet. Furthermore, you can transfer the Excel tables to RFEM 6 / RSTAB 9. We are always working to offer you even more options in RFEM / RSTAB.
DXF Format (*.dxf)
You are certainly already familiar with the DXF format. The DXF file format provides you with the most common data exchange formats available in the CAD area. DXF files can be imported as well as exported with minimum effort.
IFC Interface in RFEM 6 / RSTAB 9
Dlubal software has many different interfaces. One of them is the IFC (Industry Foundation Classes) interface. This is divided into several areas, called "Views". Furthermore, there are various versions of the IFC format. Take a closer look here. Version 4.0 is supported for both import and export. However, the older version 2x3 is only supported for import. Regardless of in which direction you exchange the data, you can process the StructuralAnalysisView as well as the ReferenceView (Coordination View).
When importing the ReferenceView, the individual IFC objects can be converted into RFEM-native elements. You can also use the conversion tables to adapt the cross-section and material descriptions. The export in the ReferenceView allows you to display the structure in IFC viewers and CAD programs. On the other hand, StructuralAnalysisView allows you to transfer the structural model including loading. As you can see, there are numerous options available to you.
STEP Interface
You can import STEP files into RFEM 6. The data is directly converted into the native RFEM model data.
The STEP format represents a standard interface initiated by ISO (ISO 10303). In the geometry description, all shapes relevant for RFEM (line, surface, and solid models) can be integrated by the CAD data models.
Note: This format is not to be confused with DSTV interfaces, which also use the file extension *.stp.
Connection to ConED
ConED has a bidirectional interface to RFEM 5. It can be used to calculate ceiling systems, deep beams, floor slabs, and entire buildings from ConED. Adjustments of any kind can still be made in RFEM 5 before the user initiates the calculation. The calculation results are read from the database via the COM interface and are imported in ConED.
SDNF Interface (*.sdnf)
The SDNF interface (Steel Detailing Neutral Format) by Intergraph is used for the data exchange with Intergraph Frameworks or Tekla Structures. Thus, the structural data in the form of nodes and members with the corresponding materials and cross-sections, but without support conditions, can be imported into RFEM 5 / RSTAB 8 and exported from RFEM 5 / RSTAB 8.
Bentley ISM Interface (*.ism.dgn)
Do you work with Bentley applications? No problem, as the implementation of the ISM interface in RFEM 5 / RSTAB 8 allows you to exchange models with, for example, ProSteel, ProConcrete. And since two are better than one: The interface works in both directions. The core of the ISM technology is the ISM Viewer V8i, which you can obtain from Bentley free of charge.
Among other things, this allows you to export surface components, such as walls and slabs, or sections with variable cross-sections, to ProSteel and ProConcrete. A particularly useful additional feature of the ISM Viewer is the output option in a 3D PDF document. Try it now!
RFEM 5 Interface to GLASER -isb cad- (*.geo, *.fem)
This interface controls the interaction with the Glaser program by isb cad: You can import the GEO files into RFEM 5 and export the results of the concrete surface design as FEM files. The import includes single lines and arcs; surfaces as slabs (circumferential geometry); centroidal lines of walls; center points of columns; openings; surface, line, and nodal loads; and free rectangular, line, and concentrated loads. The export includes the top and bottom reinforcement in FE mesh or grid points, optionally only the additional reinforcement and the shear reinforcement.
RFEM 5 Interface to DICAD STRAKON (*.cfe)
Within the data exchange, RFEM 5 supports the structural and reinforcement program STRAKON by DICAD. The structural data, such as nodes, lines, materials, surfaces, openings, and nodal and line supports are imported. The reinforcement, including the boundary lines of the surfaces, is exported. Each surface is exported individually.
CIS/2 Structural Frame Scheme (*.stp)
The CIS/2 format by NIST is particularly popular in English-speaking countries when it comes to data exchange. You can benefit from this, too. In addition to the structural data of member structures, you can import the information about loads, load cases, load combinations, and result combinations in RFEM 5 / RSTAB 8. It works very simply and easily.
RFEM 5 Interface to CADKON (*.esf)
ESF (Engineering Structural Format) allows for data exchange with the CADKON program by ABStudio. It is possible to export both planar surfaces with a constant thickness and any existing openings as well as the used materials from RFEM 5 to an ESF file.
Text Format (*.000)
It is possible to import text files in the format *.000 (structure) and *.001 (loading) into RFEM 5 / RSTAB 8 (format of the older Dlubal program PLATE).
SCIA Engineer (*.xml)
Dlubal Software works hand in hand with other structural engineering programs. One of them is the structural analysis program SCIA Engineer. The import of XML files has been implemented for the exchange with RFEM 5 / RSTAB 8. We use all opportunities to provide you with more and more interfaces.
cadwork Interface (*.stp)
Another interface in RFEM 5 / RSTAB 8 allows you to export models to the CAD program cadwork. On the other hand, it is also possible to import cadwork models. In addition to the model geometry, you can also transfer the information about cross-sections, materials, supports, and rigid couplings. Check out how easy it is:
SEMA Interface
The timber construction and framing software SEMA is popular. That is why we have provided you with an interface for the transfer of SEMA 3D structures. You can transfer a SEMA model to RFEM 5 / RSTAB 8 in the DXF or DSTV(STP) format. And the best thing is: In the latter case, it is possible to transfer not only the standard data, such as the structural geometry, but also the information about cross-sections, materials, supports, and rigid couplings. See for yourself:
Interface to Advance Steel (*.smlx)
The SMLX export (Steel Markup Language) allows you to transfer member structures from RFEM 5 or RSTAB 8 to Advance Steel. In addition to the model geometry, the corresponding cross-sections, materials, and member eccentricities can be transferred.
Interface to Hilti PROFIS Engineering Suite
This direct bidirectional interface allows for data exchange between RFEM 5 / RSTAB 8 and Hilti PROFIS Engineering Suite.
The RFEM/RSTAB support loads are transferred to Hilti PROFIS Engineering Suite. Then, the design of dowels and anchor plates is carried out. The results of the dowel design are not lost. You can import them into RFEM/RSTAB as comments.
Interface to IDEA StatiCa
It is possible to export members, cross-sections (made of steel or concrete), and internal forces from RFEM 5 / RSTAB 8 for design in IDEA StatiCa. The data are synchronized in IDEA StatiCa when the RFEM/RSTAB model changes.
Background Layers
To simplify your modeling, use background layers stored in the work window of RFEM 6 / RSTAB 9 for the input of graphical object. These layers are generated from an imported DXF file. Read more about this:
Export to SVG Format (Vector Graphics)
In RFEM 6 and RSTAB 9, you can export line graphics to the SVG format (vector graphics).
SVG stands for Scalable Vector Graphics and is an XML-based file format for displaying two-dimensional vector graphics. These vector graphics can be scaled without loss. It is possible to edit the SVG files using text editors, embed them on websites, and open them in the usual browsers.
VCmaster Interface
This interface can be used to export a printout report from RFEM 5 / RSTAB 8 to VCmaster (processing calculations and texts) by the company Veit Christoph GmbH and continue editing there.
RTF Interface
If you want to further edit a printout report of RFEM 5 / RSTAB 8 with MS Office, you can convert it, including the graphics, into an RTF file.
Add-on Modules RF-COM (for RFEM 5) and RS-COM (for RSTAB 8)
COM technology is the basis of these programmable interfaces. How does this benefit you? It enables you to program your own input macros or post-processing programs. Read more about it here:
