【Abstract】 Three-dimension visual design of railway-line is a principal development of the current CAD technology. It can predict the space situation and image of the designed railway-line,enable the designers to check design problems and eliminate loopholes and mistakes hencl avoid regrets of the completion. So 3D Visual clesign is very importunt in the field of,improving the quality of railway-line’s design.更多还原
