The invention relates to a method for operating a rotational molding apparatus that comprises a rotatably mounted rotational-molding mold holder having a rotational-molding mold. The method is characterised in that a trajectory of a reference point of a component for a rotation process, in particular a component of the rotational-molding mold holder or the rotational-molding mold, which component rotates during a rotation process, is selected from one of a plurality of possible trajectories that can be achieved by the rotational molding apparatus, and in that a rotation process is subsequently performed in which rotational-molding material introduced into the rotational-molding mold accumulates on the inner face of the rotational-molding mold and in which the reference point moves along the determined trajectory.
