摘　　要：给出了汽车车身A级曲面的概念和要求,以汽车后风挡玻璃和行李箱盖为例讨论了A级曲面的光顺流程。在基本曲面光顺过程中,提出从曲面的控制顶点排列、补片数和次数等方面保证其构造品质;在过渡曲面的光顺过程中,强调了基本曲面理论交线在过渡曲面构造中的作用;分析了采用过渡曲面边界裁剪基本曲面时应注意的问题。The conception and desirable quality of auto-body Class A Surfaces are presented.The processes of smoothing Class A Surfaces are discussed by taking rear windshield glass and luggage compartment lid as example.The arranging of control vertex,patch and degree of surfaces are presented to assure the quality of surfaces in basic surfaces smoothing.Theoretical intersection curves of basic surfaces are emphasized in transitional surfaces smoothing.And problems are analyzed in trimming basic surfaces with transitional surfaces boundary.
