1. A method for reconstructing data in a data processing system, comprising: receiving, in the data processing system, B-Rep data of a graphic model, the B-Rep data including a plurality of edges and coedges; constructing, from the B-Rep data and by the data processing system, a vertex table having coordinates of a plurality of vertices of the graphic model; constructing, from the B-Rep data and by the data processing system, an edge table associating each edge of the graphic model with at least one of the plurality of vertices of the graphic model; storing the constructed edge table and vertex table in the data processing system associated with the B-Rep data.
