In order to reconstruct complex three-dimensional solid model with holes based on slice date,a new method is proposed,which integrates a local optimization approach based on contours and marching cubes.Through using the auxiliary contours method to enhance the accuracy of contours,constituting the classification principle by the complexity of the model,choosing and configuring methods reasonably,the difficulty of multi-branch contours topological reconstruction is overcomed.And a three-dimensional surface model formed by triangular patches is created.Furthermore,a solid model is constructed from the surface model by ANSYS Parameter Design Language(APDL)in the ANSYS software,which not only can be used for three-dimensional display,but also finite element analysis.Besides,it makes the three-dimensional reconstruction method more practical.
