Urban public transport vehicles asa major means of transport should consider fort of passengers board, but also consider the coordination with the feature of the cities and play the role of beautifying the cities. Along with calculator technical development, with the help from puter to carry on digital design already more and more applications in the design realm. with puter can express the shape ofa passenger car inner part and exterior clearly, keeping the felling of view for the big and medium-sized passenger car carriage item carry on the development design, puter can the work very pletion car's shape design, also 王源 YD6906GH 型客车车身机构设计 III save the creation grease model etc. isa great deal of time of the step, lowering a development graduation design is to design the YD6906GH passenger car and the bottom in puter, to design the passenger car in the calculator of total shape design, and framework, receive skin, ex- lamp and soon. This text bine the CATIA V5 e to detailed the introduction should design the application of this method.
