Answer:
The trigger for this is the member rotation of a member. A member rotation can be defined in RFEM and RSTAB using two options:- Option 1: Rotation via Angle
- Option 2: Rotation via Help Node
Question
After importing an .stp file, there is a free node near each member. Why are these nodes created?
Do you have any questions?

The individually defined printout reports in an RFEM or RSTAB model can be displayed in different ways.
The interface to Autodesk Revit is installed automatically during the installation of RFEM 5 or RSTAB 8. Subsequent installation of the plug‑in is possible through the execution of Revit-Installer.exe.
In the age of BIM, data exchange between the various disciplines of structural engineering is becoming increasingly important. Since each software has its own specifications with regard to the description of cross-sections and materials, RFEM and RSTAB offer a conversion table (mapping file).
The ISM file (ISM = Integrated Structural Modeling) in RFEM and RSTAB provides an interesting option for exchanging data. If you export a model to this data format, you can view and analyze it with the free ISM viewer from Bentley.

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 check box '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.
When exchanging data with Advance Steel using *.smlx files, the interface is detected automatically. This means that *.smlx files can be created even if no version of Advance Steel is installed.
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
