Frequently Asked Questions (FAQ)

AnswerNo, this is unfortunately not possible.If you save the last version of your model in RSTAB or RFEM, it is done in the currently used version.However, you can also open RSTAB 8 files in RSTAB 7 and RSTAB 5 files in RFEM 4. Please pay attention to the notes in FAQ004112 in the link below.
AnswerRFEM includes a direct link to Autodesk Revit. The information about compatibility for any version can be found in Update Reports.
The files created with SHAPE‑THIN 8 cannot be opened in the previous program versions, such as SHAPE‑THIN 7. In SHAPE‑THIN 8, you cannot save files in the file format that can be read by the previous versions, such as SHAPE‑THIN 7.
However, it is possible to export the input data to Excel in SHAPE‑THIN 8 (Figure 01) and import them into SHAPE‑THIN 7 after adjusting the column arrangement. This is also shown in the video.
AnswerIn SHAPE‑THIN 8, it is possible to open the cross-sections created with the following program versions:
- SHAPE-THIN 5.xx,
- SHAPE-THIN 6.xx,
- SHAPE-THIN 7.xx,
- SHAPE-THIN 7.5x, and
- SHAPE-THIN 8.xx.
However, it is not possible to import the cross-sections created in the DOS versions SHAPE‑THIN 1.xx and SHAPE‑THIN 2.xx into SHAPE‑THIN 8.
That is possible. If you select "All Files" in RSTAB 7 under "Open" for the file type, RFEM also shows RSTAB 8 files. They can be opened.
A warning message appears because it is, of course, not possible to consider features that were not contained in the older version.
Another possibility is to rename the file from * .rs8 to * .rs7 and open it directly. The warning appears even then.
This procedure is the same for RFEM.
In RFEM, it is possible to open and further edit structures with loads and load cases, which has been modeled in RSTAB. This may be necessary, for example, if it is determined during the model input that it makes sense to include surface elements such as wall panes in the existing RSTAB model.
In order to open an RSTAB file in RFEM, you have to change the file type in the 'Open' dialog box either to 'File type RSTAB' or to 'All Files'. In this way, you can display not only the RFEM files, but also all RSTAB files stored in the selected directory. After opening the RSTAB file, you can save the model as an RFEM file for further editing.
However, it should be noted that the printout reports or input data already created in add-on modules cannot be transferred.
An RFEM file can be imported in RSTAB by renaming the file extension *.rf5 to *.rs8. Also in this case, all module entries and printout reports are deleted. You should also note that beam structures are only transferred in RSTAB; surface elements are deleted.
The relevant internal forces for concrete design can be found in the "Reinforcement Layout" tab of Window "1.6 Reinforcement." Here, you can select the internal forces, which should not be taken into account for the respective reinforcement group. Please note that this setting applies to all members of the reinforcement group. Therefore, you should use this function carefully.
The export is not possible in this direction.
In RFEM, surface elements may be available in addition to member elements. RSTAB is not able to import these surface elments because this would lead to a falsification of the structural system and so to wrong results.

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.
“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. ”
