of the bearing of the fender 9 the geometries of the fender 9 are initially imported into a cad computer aided design program step a of the flow diagram the cad program thereupon generates the cad model 20 of the fender 9 the cad program can run on the control computer 8 or on an external computer not shown in detail in figures after importing the geometries of the fender 9 its cad model 20 is presented by means of the display device 12 connected with the control computer 8 or by means of a display device not shown in detail of the external computer an operator not shown in detail in figures thereupon selects in the cad model 20 a measuring point 21 and configures the number of the degrees of freedom to be measured and the position relative to the coordinate system of the fender 9 of a measurement device 10 attached on the flange 7 for the measurement of the fender 9 depending on the employed measurement device 10 one degree of freedom or two or three degrees of freedom can be selected for the measurement step b of the flow diagram in the case of the present exemplary embodiment the operator selects the measuring point 12 by.
