<p>A device for generating complete data sets for the determination of a workpiece contour. Sections of a workpiece contour are input into a data memory in the form of incomplete data sets. A computer applies a contour algorithm to link the incomplete data sets into complete data sets of the workpiece contour by combining the geometric data contained in the data sets. The complete data sets are applied to a result memory and/or to a graphic unit for display. The workpiece can then be represented on a display screen and/or the workpiece generated on a numerically controlled machine tool.</p>
