I'm wondering how I would make an object have lines on some edges when rendered, like it was drawn. I believe the feature is called freestyle, and I activate it in the render options, but my test cube doesn't render with the lined edges. What I'm asking, to be clear, is how to make an object that renders with hard lines on edges to give the appearance of being drawn in blender 2.7 cycles render. The blender wiki has outdated info about this.
Enable freestyle in the properties->Render window: You can control the line thickness there.
The controls for the shading are in properties->scene->line_style->Freestyle Line set and Line style.
