Frequently Asked Questions (FAQ)

Importing * .igs or * .stp (STEP) files requires the RX-LINK add-on module (see Figure 01). Exporting is currently not possible.
You can additionally import a model with the CAD/BIM option. After selecting the file to be imported, it can be activated in the Options tab of the "New Model - General Data" dialog box (see Figure 02). With this option, you can additionally convert the geometric elements directly into members, surfaces, or solids after the import (see Figure 03).
As CAD software, SolidWorks currently provides the output via the IGES and STEP interfaces, which can be imported by our software but can not be exported. For the greatest possible comfort, the CAD/BIM option should be activated (see link).
In addition, it is also possible to exchange data via DXF files. Here, RFEM is also able to export or import 3D structures and surfaces.
AnswerIf you are using members with cross-sections, which are not known be the interface, you should use the mapping file for cross-sections. The mapping file can be easily filled with the names of the cross-sections. In the left column of the table write the names of cross-section used in TEKLA and in the right column you write the DLUBAL names or select them from the library.Please check the attached video.Note:
In TEKLA you have to have loaded the right environment. In the video Chinese cross-sections should be transferred, so the Chinese environment has to be used in TEKLA.
AnswerCurved members are described by the external enveloping surfaces in the Cadwork program and in many other CAD-based programs. Therefore, a direct import via members is not possible.For this reason, the member has to be first imported from the CAD program in .sat format (Standard Acis Text Format) or .ifc as a surface in RFEM and then re-imported to a member.When using the .sat format, it is necessary to select the Version 7.0 in Cadwork.The attached video shows both options for the program Cadwork.
AnswerThere can be several reasons for this.
- It may i.a. be caused by the fact that the DXF file contains only blocks that have first to be separated e.g. by means of the ‘Explode’ function .
- Another source of problems may consist in the fact that a specific layer is selected for import in the ‘DXF ASCII Formats’ tab of the RFEM or RSTAB import dialog box that either does not exist or contains no data.
- The type of backup in the CAD program may also cause some problems. It is possible to save DXF files in the binary DXF format. Their advantage consists in saving about 25% of the memory size. However, they cannot be processed by RFEM and RSTAB. Therefore, to save the DXF file, the ASCII format should be selected in the CAD program.
AnswerRFEM includes a direct link to Autodesk Revit. Compatibility information for any version can be found in the Update Reports.
AnswerThe message displayed in Figure 1 appears when trying to open a DXF file using the File → Open menu option or the corresponding toolbar button. To import the DXF file, select File → Import from the menu (Figure 2). Importing a DXF file is demonstrated in the video.
AnswerTo import background layers as DXF, use the 'Import as background layer' option in the 'Import Settings'.
AnswerIt is possible to export the effective lengths from the add-on module to EXCEL as shown in Figure 1.
AnswerThe modified cross-section must be reimported into RSTAB/RFEM. To do this, click the 'Import Cross-Section from Program SHAPE-THIN' button in the 'Edit Cross-Section' dialog box and select the modified SHAPE-THIN cross-section. The query of overwriting the cross-section should be answered with 'Yes' (Figure 1).
