A cut data generating device includes a control device which causes the generating device to acquire data indicating a pattern, to extract outlines of plural subpatterns contained in a design, to determine the number of layers associated with the number of sheets with respect to the extracted outlines, and to determine a sequence for stacking plural layers. The control device further causes the generating device to generate an integrated outline obtained by integrating the outline of first and second subpatterns contained in the extracted outlines, to specify the outline of the first subpattern on a first layer, to generate cut data for cutting the outline of the first subpattern from a first sheet associated with the first layer and for cutting the integrated outline from a second sheet associated with the second layer, and to output the generated cut data via the communication unit to the cutting apparatus.
