End of Segment command inserts a partition line into a column or appliqué, dividing it into segments. One endpoint of the new segment-end line is the selected node, and the other endpoint is found automatically on the opposite side (the nearest node).
Segment ends define the stitch direction inside the column or appliqué. When generating stitches for columns and appliqués, the program takes into account the direction of segment-end lines and conforms the stitch direction at those locations.
End of segment - effect on the stitch directions.
