At the bottom center there are 2 adjacent polygons with opposing Normals. What is non-manifold geometry? Non-manifold geometry describes edges that share more than 2 polygons. This type of geometry should be avoided since it can lead to a series of issues, e.g., for rendering or 3D printing, etc. **Resolve Non-Manifold** "repairs" these regions by evaluating the affected regions and creating separated polygons/points accordingly.
