Changing the Global Coordinate System Subsequently

Before creating a structural model, every user gives thought to the boundary parameters of the system and how best to represent the model. Special attention should be paid to the orientation of the global coordinate system. In engineering, the global Z‑axis is usually oriented downwards (in the direction of the dead load), while it tends to be upwards in architecture. These differences can often lead to complications during modeling; for example, when you replace global models or DXF layers.

In RFEM and RSTAB, you can, therefore, subsequently change the orientation of the global axes. You can specify the appropriate settings in the General Data of a model.

As a special note, however, it should be mentioned that the subsequent modification of these axes, especially with regard to the applied load (also orientation-dependent), can very easily cause application errors; therefore, this function should be used only as an exception.
