A sewing machine includes a sewing portion sewing an embroidery pattern on a cloth, a first storage portion storing the stitch data and pattern data, a display portion, a processor, and a memory storing computer-readable instructions. The computer-readable instructions, executed by the processor, includes first acquiring the stitch data and the pattern data, and first displaying, based on the pattern data, the pattern image on the display portion. The computer-readable instructions also includes, first generating a plurality of partial images representing a number of stitches corresponding to a first predetermined number, based on the stitch data, after the first displaying of the pattern image on the display portion, and second displaying, each time each of the plurality of partial images is generated by the first generating, the generated partial image on a portion of the pattern image displayed by the first displaying that corresponds to the generated partial image.

A sewing machine includes a first image acquisition unit, a second image acquisition unit, and a display unit. In the sewing machine, the first image acquisition performs image acquisition from the front face side of a cloth for a stitching pattern formed in the cloth. The second image acquisition unit performs image acquisition from the back face side of the cloth such that the center position of the acquired image matches the center position of the image of the stitching pattern acquired by the first image acquisition unit. The display unit displays, on the same screen, a first stitching pattern video image thus acquired by the first image acquisition unit and a second stitching pattern video image thus acquired by the second image acquisition unit.

A controller acquires sewing data for sewing an applique piece on a sewing target material, the applique piece having a shape having a hole, the hole being a closed area surrounded by at least part of the applique piece, identifies a contour of the applique piece while distinguishing an inner contour and an outer contour, the inner contour being the contour defining the hole of the applique piece, the outer contour being the contour other than the inner contour, determines, based on the acquired sewing data, whether an inner stitch and an outer stitch are arranged at positions closer to each other than a particular distance or at positions overlapping each other, and outputs an error notification in response to determining that the inner stitch and the outer stitch are arranged at positions closer to each other than the particular distance or at positions overlapping each other.

A processing data generation device includes an input portion, a processor, and a memory. The processor is configured to receive a detection signal of the input portion. The memory configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include pattern identification processing of identifying a target pattern, region specification command acquisition processing of acquiring, via the input portion, a region specification command to select, as a cutting region, a first region surrounded by an outside of the target pattern and by the target pattern, and processing data generation processing of creating processing data for cutting out, from a workpiece to be cut, the cutting region specified by the region specification command, as an applique piece.

A non-transitory computer-readable medium stores computer-readable instructions, when executed by a computer, causing the computer to execute a process. The process and a method of generating embroidery data each includes: obtaining a pattern to be sewn on a workpiece by a sewing machine; obtaining a size of a sewing area to be set inside an embroidery hoop attachable to the sewing machine; setting a virtual arrangement of a plurality of the sewing areas relative to the workpiece; setting a virtual arrangement of the pattern relative to the workpiece; changing a relative position of the sewing areas; and generating embroidery data including needle drop data, the needle drop data representing a plurality of coordinates of needle drop points to form a plurality of stitches for the pattern located in each of the sewing areas in the relative position changed.

Embodiments herein describe creating parent composite actions that can include multiple child objects. The child object can be needle point paths or child composite actions (which also include needle point paths). For example, a parent composite action can include a mix of child composite actions and needle point paths, only child composite actions, or only needle point paths. The needle point paths in the parent composite action can be translated into a single needle point path which can then be converted into a machine embroidery file.
