Answer:
In RFEM 6, a foundation cannot be rotated directly. The orientation is determined via the local coordinate system of the associated nodal support. To do this, a user-defined coordinate system is created and assigned to the nodal support. The foundation automatically adopts this orientation. A prerequisite is that the local Z-axis of the nodal support runs parallel to the global Z-axis. The orientation of a column has no effect on the orientation of the foundation.
