Non-transitory computer-readable storage medium storing sewing data generation program, and sewing data generation device

A sewing data generation device comprising:

• a processor;
• and
• a memory storing computer-readable instructions that, when executed by the processor, perform processes comprising:
• acquiring, for each of a plurality of embroidery patterns, pattern data to sew the embroidery pattern including a plurality of partial patterns which are sewn using mutually different types of thread, the pattern data including thread data and coordinate data, the thread data indicating the type of the thread for each of the plurality of partial patterns, and the coordinate data indicating positions of stitches to be sewn using the thread of the thread data;
• determining whether first common data is included in the pattern data of a first embroidery pattern and the pattern data of a second embroidery pattern, of the plurality of embroidery patterns, the second embroidery pattern being the embroidery pattern that is sewn subsequently to the first embroidery pattern, and the first common data being the thread data indicating the same type of thread;
• setting, when it is determined that the first common data is included in the pattern data of the first embroidery pattern and the pattern data of the second embroidery pattern, a sewing order of the stitches represented by the pattern data of the first embroidery pattern, while causing the partial pattern to be sewn using the thread of the first common data to be the partial pattern that is last in the sewing order in the first embroidery pattern;
• and
• setting, when it is determined that the first common data is included in the pattern data of the first embroidery pattern and the pattern data of the second embroidery pattern, a sewing order of the stitches represented by the pattern data of the second embroidery pattern, while causing the partial pattern to be sewn using the thread of the first common data to be the partial pattern that is first in the sewing order in the second embroidery pattern.
