Standard Line Styles
Standard line styles (also known as line codes), numbered 0-7, are based on output device coordinates, and therefore are not truly WYSIWYG (what-you-see-is-what-you-get), as are custom line styles. Hence, it is recommended that you use custom line styles instead of standard line styles.
Note: Line Styles 1–7 are disabled while DWG workmode is in effect. Only custom line styles are active in this mode.
