Closed graph reinforcement means to sew designated number of stitches forward after the end
point (i.e. stitch start point) is reached, and then return to the stitch start point; overlapping
reinforcement is performed between these two points. Closed graphs refer to enclosed graphs
composed of circle, rectangle, and polygon whose start points are completely coincident with end
points.
Shrinkage suture: The stitch length is reduced based on the default stitch length for bar tacking
sewing. If the default stitch length is 3mm, the parameters set as shown in the figure below mean all
stitch lengths within the distance of 9mm from start point of curve are 1.5mm, while the stitch length
in other parts is 3mm by default.
：
Repeated stitches are required at the end of the line
segment.
Lambdoidal suture: V or N-shaped bar tacking sewing. The parameters set as shown in the left
figure below bring about the reinforcement effect shown in the right figure.
