【Abstract】 By the analysis of the structures of STL files and based on the structure of undiagraph, the adjoining relationship among the triangles is constructed by which one can search for a triangle and slice easily. A slicing algorithm is studied and the problems which may happen during the slicing process are discussed. Some methods to solve the problems are proposed too. At last, a Double Link List is used to express the CAD mold after slicing.更多还原
