摘　　要：依据A级曲面的几何连续条件,论文从控制点入手对曲面拼接的连续性进行分析。对于大曲率半径的简单曲面拼接,曲面分段的方法可以有效地提高曲面连续性调整效率和质量;对于复杂的小曲率半径多面拼接,从特征线入手,创建基础曲面,与相交的过渡面倒圆角,再合理地划分曲面片,确保曲面拟合精度和曲率连续过渡。经过实际应用表明,合理地设置控制点,从特征线开始构面,再以圆角面为基础进行曲面拼接,有效地提高了曲面光顺效率和质量,可以得到良好的品质。According to the geometrical continuity condition of class A surface,this paper analyzes the continuity of surface stitching from the control points.For simple surface stitching with large radius of curvature,the segmented method can effectively improve the efficiency and quality of surface continuity adjustment.For complex multi-surface stitching with small radius of curvature,the basic surface was created from the feature line,and the intersecting transition surface was filled-off,and then the surface pieces were divided reasonably to ensure the fitting accuracy and continuous transition of curvature.The practical application shows that the reasonable setting of control points,starting from the feature line,and then using the rounded surface as the basis for surface stitching,can effectively improve the surface smoothing efficiency and quality,and can get good quality.
