补充资料：补片教程－补六边缺口
补此面的方法：
1、insert /points set/points on curve/
选项中number of points 选的越大，补出的面质量越高
2、insert /free form feature /from point cloud
选择上部插入的点，作出补丁面
3，insert /form feature /extract curve
从空缺多边形的边缘提取出曲线
4、insert /form feature /extruded body
沿垂直曲面方向（此处可用草图建模作方向线）
拉伸上述曲线，制作切割工具面
5、insert /form feature /trimmed sheet
用上步拉伸的曲面切割上面作出的补丁面
6，inser feature operation / sew
缝合 that is all .
