I suppose there are a number of areas where over ride buttons could be used, but the philosophy at COADE is that our software is driven by the dictates of the codes, except where the code is silent, in which case we use published and accepted methods (eg Zick, WRC107 etc).

In the case of cone to cylinder junctions, this problem is quite a difficult one, because it is impossible in some case to avoid violating the requirements of the code.
