<p>Abstract The invention relates to a self-propelled civil engineering machine, and in particular to a slipform paver, road paver or road milling machine, and to a method of controlling a self propelled civil engineering machine. The civil engineering machine according to the invention has a control unit 7 which has means for determining data which defines the position and/or orientation of a reference point R on the civil engineering machine in relation to a reference system (X, Y, Z) independent of the position and orientation of the civil engineering machine. The reference system (X, Y, Z) independent of the machine related reference system (x, y, z) may be selected as desired, and there is thus no need for the positions of various reference points to be plotted on the ground. The civil engineering machine is moved to a preset starting point on the ground which may be freely selected. At the preset starting point, the civil engineering machine is aligned in a preset orientation. The position and orientation of the object are thus laid down. Consequently, the object can always be optimally arranged on the ground with due allowance made for possible fixed points. As well as this, the civil engineering machine also has means for determining data defining a desired curve in the reference system (X, Y, Z) independent of the position and orientation of the civil engineering machine and means for controlling the drive unit, as a function of the data defining the desired curve, in such a way that the reference point R on the civil engineering machine moves along the desired curve starting from the preset starting point at which the civil engineering machine is in a preset position and orientation on the ground.
