The refactoring method about 3D model's horizontal profile for Additive manufacturing

Deal with the problem that direct contour of the cross-section in 3D model is discontinuous curvature. A kind of curve rebuilding method is proposed. Firstly, using the location relationships between the section and the model solve the crossover points. Then, using high interpolation function fits those points to get the section-profile's fitting curve. Finally, analysis the error of the fitted curve. Resolutely, using this curve to replacement the direct curve is accurate in AM. In the same time, this method can solve the problem that direct contour is discontinuous.
