Abstract
A three-dimensional shape data processor for processing data concerning a three-dimensional shape to be formed on a flat plate has a synthesis processing means (5 and 6) for performing synthesis processing such that three-dimensional shape data are partially superimposed on one another, and at an overlap portion, either one of the three-dimensional shape data is left as it is, while the other is erased, and an interpolation processing means (7) for performing interpolation processing by providing a predetermined interpolation region at a boundary between the three-dimensional shape data subjected to the synthesis processing. Interpolation is performed so that the height changes continuously between the three-dimensional shape data combined together through the interpolation region. An engraving apparatus cuts a flat plate immersed in a cutting fluid, thereby preventing cuttings from depositing on a cutting blade or the plate being engraved even in the case of a noble metal. Thus, engraving quality can be improved.
