3、lenodeswillremainunchangedandtherestofthesurface/partwillberemeshed.这个操作是自动重新划分网格的一个操作项目。这个局部网格重新划分参数允许用户给好几个网格划分不同的参数。如果有任何不实现形状的三角形质量阈值，在这个操作执行之后记录器会显示三角划分失败百分比。如果控制边缘长度检查，最大和最小的三角形边的长度要求将包括在相同的分析和总结。此外，如果这部分里包含有图标结构在里面，就在重新网格划分，那么所有点之间的连接图/三角形节点将保持不变,其余表面/部分会再啮合。Parameters参数AutoRemesh白动网格划分4Sflls
