In order to use all functions for intersections developed in RFEM 5, you can select the "Create surface components as stand-alone partial surfaces" check box in General Data of the model ("Edit" → "Model Data" → "General Data"), "Option" tab. Thus, the active and inactive partial surfaces are imported automatically.
In this way, it is now possible, for example, to deactivate several components at the same time using the shortcut menu (right‑click the selected surface), specify different thicknesses for the individual components, and apply the FE mesh refinement relevant for the component.
