With a radial fill area selected, Control–click and choose Edit Radial Fill.
With a radial fill area selected, click the Properties button.
Convert a fill area to Radial Fill in the Object window. The Properties dialog appears.
Create a radial fill at the chosen density. The lower the number, the closer together the stitches and the more stitches are produced. You can set Density from 2 to 40. The initial setting is 20.
Use the slider or the numbers box to set the Density.
