For the first case (making the wire visible), simply model it as a thin object to make it visible in the rendering. One consideration here is that it is likely very inefficient to do this with round objects (even though the wire may actually have a round cross-section). For example, the default circle in SketchUp has 24 side segments—extruding it along a straight line creates 26 faces (24 sides plus the top and bottom faces). Extruding it along a curved line creates many more faces because the geometry needs to fold around bends. (See Figure 5-22.)
