| Abstract: | The unfolding of right sustaining beam of the complex shape autopanel has been researched by the method of parallelogram-projection and emit-projection based on sheet neutrosphere.The spread outline of the part can be attained through connecting the spread line end by UG software with help of two projections.Finally,a reasonable blank outline has been calculated.The rule that the part and its blank are equal in the area proves the accurate outline. |
