Unifying the Normal (New for v3.0)

If you use the Flip function and you still fail to mend the holes or cavities on the surface, then you might need to apply the feature in this section. Unifying the normal adjusts all the normals outward or inward so that the holes on the surface are fixed.

To unify the normals, please follow the steps below:

1. Select the object with holes on the surface caused by some unknown reasons.
   
2. Open the Edit Normals panel by accessing the Modify menu >> Edit Normals command.
   
   
3. Click the Unify button. The normals of all meshes will be unified to the same direction. However, in this example, they are turned to face downward.
   
4. Utilize the Flip Face Mode feature to turn the normals in the ideal directions.
