This paper illustrates the rationale of the frequent and considerable modifications made in the last few years to the design of the toroidal field coils (TF) and the central solenoid (CS) of the two international projects NET and ITER. Only one concept of the superconducting coil and the central solenoid survived the continuous changes: that all the coils were to be built using the pancake technique. In 1992, another technique was proposed for ITER called the layer-by-layer technique. The advantages and disadvantages of the two techniques are being analysed by associated laboratories and industries, and the most recent results of these studies and those of other construction proposals are described.
