3 options are available for the solid edges:
Auto- draws the material color if faces are not displayed. Uses black or white if the faces are displayed.
Specified- used the color specified next to the solid edges
Material- displays the material color of the solid
The Solid faces item causes the faces of the solid to be drawn as filled polygons.
