Abstract:
1. A sewing data creation apparatus for creating sewing data required for sewing by a sewing machine, the apparatus comprising: a unit pattern storage device that stores pattern data of a unit pattern of a predetermined design; a pattern disposition device that determines a position of the unit pattern stored in the unit pattern storage device on a stitch path, the stitch path including at least a curve-like portion; a sewing data creation device that creates the sewing data for forming stitches on the stitch path and stitches of the unit pattern at the position determined by the pattern disposition device; a profile line network creation device that continuously arranges unit areas with a predetermined shape in a sewing area to create a profile line network, the profile line network including an aggregate of profile lines of the arranged unit areas and providing a basis for creating the stitch path; a starting point-and-ending point determination device that determines a starting point and an ending point of the stitch path from points on the profile line network; a path creation device that creates the stitch path by connecting the starting point and the ending point on the profile line network in an intersection-less line; a movement determination device that determines whether a partial path may be moved in such a manner as to be longer on the profile line of at least one unit area where the partial path is disposed, the partial path being a part of the stitch path created by the path creation device and continuously disposed on the profile line of the at least one of the unit areas; a movement device that moves the partial path determined to be moved by the movement determination device in such a manner that the partial path is longer on the profile line of the at least one unit area; and an adjustment device that adjusts the stitch path by causing the movement device to move the partial path until there is no more partial path determined to be moved by the movement determination device, wherein the pattern disposition device determines the position on the stitch path adjusted by the adjustment device.
