Use 2D View with Stitch Points to see the individual stitches in your embroideries as lines with no shading, and to display the black dots that show the stitch points (needle insertions) into the fabric.
When you zoom in, the stitch points are displayed as small squares. Showing the stitch points may be helpful for inserting new stitches, moving stitches and pasting stitch blocks.
