Abstract Generat ing dimension chain is one of the components of computer-aided tolerance design based on assembly which also includes three other components, tolerance representation, tolerance analysis and tolerance synthesis. It is the base of tolerance analysis and tolerance synthesis. The algorithm of generating assembly dimension chain automat ically based on entity-relationship model and a new algorithm in 1D based on searching direction which can generate mating relation graph are proposed. In the new algorithms, the option of the direct ion of relation is added in order to reduce the complexity of mating relation graph. In addition, the algorithms can distinguish the redundancy in relations.
