Extending it to three variables and the level surfaces are sheets with zero thickness. Going beyond to functions of four variables and thickness loses its meaning because what we define as thickness only makes sense when visualising 2D or 3D. To understand level curves one should learn the basic principles of analytical geometry first. If one understands how to plot parabolas..."
