Select a Line Style from the Styledropdown menu. This determines whether your Smart Shape will be a character, or a solid or dashed line.
If you’ve selected line, you can set the thickness, and the dash settings for a dashed line. If you’ve selected a character, such as in the case of a glissando, you can change the character, font, and set the vertical offset from a baseline.
Set the line adjustments for the start and end of the line, arrowheads, hooks, or related text.
