Answer:
To do this, you have to model the entire structure (panes, spaces between panes, and supports) directly in RFEM.
The design of the panes can then be carried out by means of the "global calculation type" in RF‑GLASS.
In this case, the only difficulty is that the loading from climatic loads cannot be applied automatically, but must be defined manually.
As an aid to modeling, you can use a temporary model.
