Four highlight line configuration types, such as reflection, projection, isocline, reflection contours, for evaluate the curves and curved surface quality had been studied in the 3D assembly environment. Finally, a comparative analysis of impeller base surface has been given by the four typesin a 3D impeller assembly.enassembly environmentcurved surface qualityhighlight line analysisArticle514.18
