Efficient Planning with BIM

BIM (Building Information Modeling) is an efficient working method for the planning and realization of buildings, which is based on a network of all participants in the building process.

All relevant building data is included in a 3D model, which is then used throughout all of the planning stages. In this way, it is not necessary to use different models created in various CAD and structural analysis software, but the same model, which can be directly transferred between the programs.

  1. Data exchange between Autodesk Revit Structure and RFEM

    Structural Analysis Programs by Dlubal Software and BIM

    It is very important for Dlubal Software to provide options for planning in compliance with BIM. Numerous interfaces implemented in the structural analysis programs RFEM and RSTAB facilitate data exchange with commonly used software (such as CAD programs) and make it easy and comfortable.

    The following overview shows a range of the interfaces integrated in RFEM and RSTAB by default.

  2. Detail settings of import

    General Information About Import and Export

    For the following interfaces and exchange file formats (except for MS Excel and CSV), it is possible to manage the materials and cross-sections by means of user-defined conversion files.

    Plausibility checks after import or before export are also possible, of course. Optionally, only selected objects can be exported. You can also define the orientation of the Z-axis for the data exchange. Similarly, coordinates can be mirrored or even switched.

  3. Interface with Tekla Structures

    Interface with TEKLA Structures

    There are three options for data exchange between RFEM/RSTAB and Tekla Structures: The stp interface allows for a file-based transfer of framework models in both directions. The analytical model generated and contained in Tekla Structures can be transferred to RFEM/RSTAB using another direct interface. Finally, a further direct interface is provided to exchange and adjust physical models in both directions.

  4. Autodesk Revit Structure Compatible

    Integration in Autodesk Revit

    The direct bidirectional RFEM/RSTAB interface with Autodesk Revit leaves nothing to be desired: 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. Even subsequent modifications in both the Revit and the RFEM/RSTAB model can be easily aligned.

  5. Autodesk AutoCAD Compatible

    Integration in Autodesk AutoCAD

    In addition to data exchange using DXF files, RFEM/RSTAB supports direct exchange with AutoCAD by Autodesk. This interface uses the latest .NET technology. You can start the data exchange directly in RFEM/RSTAB.

  6. Deutscher Stahlbau-Verband DSTV

    Product Interface for Steel Construction (*.stp)

    In order to transfer models consisting of members only, the DSTV product interface for steel constructions was implemented (German Steel Construction Association). Therefore, it is possible to exchange data between RFEM/RSTAB and other programs such as "Bentley ProStructure 3D", "Tekla Structures", "Bocad", "Intergraph Frameworks", "Graitec Advance Steel", "Cadwork", and many others.

  7. CIS/2

    CIS/2 Structural Frame Schema (*.stp)

    The CIS/2 file format of NIST (National Institute of Standards and Technology) is frequently used for data exchange in English-speaking countries. In addition to the structural data of frameworks, it is possible to import the information about loads, load cases, load and result combinations.

  8. Microsoft Excel / OpenOffice.org Calc

    Microsoft Excel

    In order to reuse or prepare values entered in RFEM/RSTAB tables, there is a direct interface to Microsoft Excel. You can directly export the RFEM/RSTAB tables - individually or all at once - to an Excel spreadsheet and vice versa. Even the formulas for parametric input can be prepared in Excel and imported to RFEM/RSTAB.

  9. DXF File Format

    DXF File Format (*.dxf)

    The DXF file format is one of the most common data exchange formats in the field of CAD programs. RFEM and RSTAB support the import and export of these DXF files.

  10. IFC interface

    IFC Interface

    The IFC interface (Industry Foundation Classes) is divided in several areas called views. When importing and exporting data, the StructuralAnalysisView is primarily supported. This means that you can transfer the structural model including member elements, concentrated loads, linear and member loads, supports, support conditions, load cases etc. The most important elements from the CoordinateView containing graphical elements are imported additionally. Click the links below to see the online description of the interface and general information concerning IFC.

  11. SDNF interface

    SDNF Interface (*.sdnf)

    The SDNF interface (Steel Detailing Neutral Format) by Intergraph is used to exchange data with Intergraph Frameworks or Tekla Structures. It is possible to import as well as export a variety of structural data like nodes and members including relevant materials and cross-sections to and from RFEM/RSTAB. The transfer of support conditions, however, is not possible.

  12. Bentley ISM

    Interface with Bentley ISM (*.ism.dgn)

    Due to the implementation of the ISM interface in RFEM/RSTAB, it is possible to exchange models with ProSteel, ProConcrete, and other Bentley applications. The interface works in both directions. The ISM technology core piece consists of the ISM Viewer V8i provided for free by Bentley.

    Furthermore, you can export surface elements like walls and plates as well as sections with variable cross‑sections to ProSteel and ProConcrete. Another useful feature of the ISM Viewer is the possibility to create 3D PDF documents.

  13. GLASER -isb cad-

    RFEM Interface with GLASER -isb cad- (*.geo, *.fem)

    This interface control the interaction with the program Glaser by isb cad: It is possible to import GEO files to RFEM and export results of concrete surface designs in FEM files. The import includes single lines and arcs, surfaces as slabs (contour lines), center lines of walls, center points of columns, openings, surface loads, linear loads, nodal loads, free rectangular as well as line and concentrated loads. The export includes the top and bottom reinforcement in FE mesh or grid points. Optionally, you can export only the additional reinforcement or the shear reinforcement.

  14. DICAD STRAKON

    RFEM Interface with DICAD STRAKON (*.cfe)

    RFEM supports the data exchange with the structural engineering and precast program STRAKON by DICAD. The import includes structural data such as nodes, lines, materials, surfaces, openings, nodal and line supports. The export covers reinforcement including border lines of surfaces. Each surface is exported separately.

  15. Nemetschek Allplan

    RFEM Interface with Nemetschek Allplan (*.asf)

    With the ASF file format by Nemetschek, RFEM supports the widespread CAD program Allplan. The import includes structural data such as nodes, lines, materials, surfaces, openings, node and line supports. The export covers reinforcement including border lines of surfaces. Each surface is exported separately.

  16. ABStudio

    RFEM Interface with CADKON (*.esf)

    The ESF file format (Engineering Structural Format) enables data exchange with the program CADKON by ABStudio. In ESF file format, it is possible to export plane surfaces with uniform thickness and potential openings as well as materials used in RFEM.

  17. Scia Engineer

    Scia Engineer (*.xml), Textformat (*.000)

    In order to exchange data with other programs used for structural analysis, the import of XML files from Scia Engineer was implemented. In addition, it is possible to import text files of the formats *.000 (structure) and *.001 (loads) to RFEM/RSTAB (the format of the former program PLATTE by Dlubal Software).

  18. Cadwork

    Interface with Cadwork (*.stp)

    This interface enables the export of models to the CAD program Cadwork and the import of Cadwork models to RFEM/RSTAB. Besides the model geometry, the transfer includes information about cross-sections, materials, supports and rigid couplings.

  19. SEMA interface

    Interface with SEMA

    This interface enables the import of 3D structures created in the timber construction and design software SEMA. A SEMA model can be transferred to the programs by Dlubal Software using the DXF or the DSTV(STP) file format. DSTV includes not only the structure geometry but also information about cross-sections, materials, supports, and rigid couplings.

  20. Hilti

    Interface with Hilti PROFIS Engineering Suite

    This direct bidirectional interface enables data exchange between RFEM/RSTAB and Hilti PROFIS Engineering Suite.

    The support loads from RFEM/RSTAB are usually exported to Hilti PROFIS Engineering Suite to perform the design of dowels and anchor heads. The results of the dowel design can be imported to RFEM/RSTAB as comments.

  21. Background Layers

    Background Layers

    Background layers are used to simplify the modeling process. The layers can be underlain in the RFEM or RSTAB work window to facilitate the input of graphical objects.

  22. VCmaster

    Interface with VCmaster

    With this interface, it is possible to export the RFEM/RSTAB printout report to the VCmaster program (for calculations and text processing), developed by the company Veith Christoph GmbH, where it can be further edited.

  23. RTF interface

    RTF Interface

    Further editing of a printout report is possible in MS Office as well. For this, the report is converted into the RTF file including all graphics.

  24. Program code in Visual Studio

    Add-on Modules RS-COM (for RSTAB) and RF-COM (for RFEM)

    This programmable interface is based on COM technology. It allows you to program your own input macros or post-processing programs.

  25. RF-LINK add-on module for RFEM

Building Information Modeling and Structural Analysis Software: Scenarios and Success Factors for Data Exchange

Building Information Modeling describes one of the most important issues in the construction software industry. This process is not new and it’s a well‑known fact that reliable planning in the early stages of a project has a significant positive effect on the project’s total cost. For more than twenty years, 3D models in the steel construction industry have been utilised so that 2D production documents could be created automatically or the related NC data could be sent directly to automatic production.
