Question:
When opening an RFEM file, the entries in RF‑CONCRETE Surfaces are lost. Is this possible?

Answer:
Yes, it is possible, for example, if a file calculated in version 5.23.01 is opened in an older version (such as 5.20.01).

The add-on modules for reinforced concrete structures have no backward compatibility. This means that the module entries must be deleted, depending on the version change.

For instance, this may be necessary if a function or feature contained in the latest program version was not available in the older version. To avoid compatibility problems, the entries in the add-on modules are removed.

In the example, the file from version 5.23.01 is opened in version 5.20.01. In this case, the entries from RF‑CONCRETE Surfaces will be lost. If you open it in version 5.17.01, for example, the entries from RF‑CONCRETE Members are also lost.

To avoid this problem, we recommend concluding a service contract and using the current version of RFEM.
