I have the SHAPE‑THIN 9 license, but I cannot transfer the created cross-section into the RFEM program. What is the problem?


The problem is in the RFEM version. SHAPE-THIN 9.01 was released together with the RFEM version 5.22.01. The files created in SHAPE‑THIN 9 have the format *.du9. The RFEM versions older than 5.22.01 do not recognize this extension, and thus the cross-sections created in a newer version cannot be loaded.


Format *.du9
