Is it possible to use a cross-section from SHAPE‑THIN 9 in older versions of RFEM or RSTAB?


Yes, it is.
The cross-section created in SHAPE‑THIN 9 (file extension *.du9) should be opened and saved as SHAPE‑THIN 8 cross-section (file extension *.du8) in SHAPE‑THIN 8.

In order to open the cross-section in SHAPE‑THIN&nbso;8, set the file type to "All Files."

Now, you can normally save this cross-section as a SHAPE‑THIN 8 cross-section, and also open it in the previous program versions.
