In the design of complicated products, there will be many modification versions. The combination of versions is universal, so a graphic version model(GVM) is needed to describe the combination. The GVM can represent the relation and evolution record of versions intuitionally and legibly. According to the theory of directed acyclic graph, the GVM in the version management is built, and the method of rebuilding graph for 2D table are studied and dynamical display of GVMis implemented.
