Manifold Mesh

Checks whether mesh topology is manifold: each surface edge should belong to exactly two faces, with no boundary or non-manifold edges. Loose geometry is handled separately by the Connected Geometry check.

Critical Automatic fix: No Settings: No Selection: Edges

Why this check exists

Manifold topology is important for reliable Boolean operations, physics and fluid simulations, solid geometry workflows, and 3D printing.
