HI Sonya, The osg::LineSegment is just an object for providing a representation of mathamtical line segment, such as required for intersection testing, it has no rendering support as it's not indented for this purpose.
The class you want to use is osg::Geometry, have a look at the osggeometry example to see how to set up lines. Robert.
