我想，错误的原因是出现在曲线的选择上，网格方向的所有曲线都应该保证交叉并完整，还有不应该使用sweep这个命令，这只适合于1-2条引导轨道的情况。应该如图片所演示的步骤使用network工具。
（I think the reason for the error is in the selection of curves. All curves in the grid direction should be ensured to intersect and be complete, and the sweep command should not be used, which is only suitable for 1-2 guide tracks. You should use the network tool as shown in the picture.）
