A square wave is indeed the result of adding together the fundamental sinusoidal wave with decreasing power of the odd harmonics. In other words if you take a fundamental sine wave and then add to it, in phase, its third harmonic at one-third the amplitude plus the fifth harmonic at one-fifth amplitude and so on then the further you go the closest you will get to a perfect square wave. Try drawing it on a piece of paper and you'll see.
