    There are two ways to enter cross-sections that are not contained in the cross-section library into the RFEM/RSTAB.

    1. Cross-section programs SHAPE-THIN and SHAPE-MASSIVE 

    User-defined cross-sections can be created by means of the cross-section programs SHAPE-THIN or SHAPE-MASSIVE. The SHAPE-THIN or SHAPE-MASSIVE profiles can be imported via the cross-section library. To do this, click the 'Import Cross-Section from Program SHAPE-THIN' or 'Import Cross-Section from Program SHAPE MASSIVE' in the 'New Cross-Section' dialog box (Figure 1). In this dialog box, it is possible to select and import the desired cross-section. Please note that the cross-sections must be calculated and saved in SHAPE-THIN or SHAPE-MASSIVE before importing the cross-section values. It is only possible to import each cross-section individually.

    2. Creating user-defined cross-section in RFEM/RSTAB 
    If the cross-section values of the manufacturer are known, they can be created in the cross-section database of RFEM/RSTAB using the option 'Create New User-Defined Cross-Section' (Figure 2). In contrast to the cross-sections created with SHAPE-THIN or SHAPE-MASSIVE, these user-defined cross-sections cannot be designed in add-on modules such as RF-/STEEL EC3, because the data necessary for the design - such as c/t-parts - is missing.

    To access the user-defined profiles, click the 'Load Saved User-Defined Cross-Sections' button in the cross-section library (Figure 3).

    User-defined cross-sections are saved across all items in the EigProf.dat file. Even when jumping a version (for example from X.19.XXXX to X.20.XXXX), these cross-sections shall be imported. The storage location of the user-defined cross-section library can be specified in the Program Options (Figure 4). It is possible to copy a user-defined profile database already created on a work center and paste it into the respective directory of the other work center. The user-defined profiles are thus also available on the other work station without having to import them again.
  • Answer

    It is possible that the user-defined profile database EigProf.dat is missing on your computer or it is damaged. Please open the 'Data Directories' tab of the program options and select the 'User-Defined Cross-Section Library' category.

    Open the displayed directory and check whether the EigProf.dat file is available. If the file is available, please rename it.


    If the path including the file does not correspond to the default path for RFEM 5.20 'C:\ProgramData\Dlubal\RFEM 5.20\General Data\EigProf.dat' in the program options, set this default path in the program options.

First Steps

First steps

We provide hints and tips to help you get started with the main programs RFEM and RSTAB.

Wind Simulation & Wind Load Generation

With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

Your support is by far the best

“Thank you for the valuable information.

I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
