Booleans limitations

• Co-planar faces may cause boolean operations to fail.
• Along the intersection of the meshes, booleans do not support:
  • non-manifold geometry
    Note: Non-manifold meshes are only supported by booleans if the non-manifold components are not at the intersection of the boolean operation.
  • self-intersecting geometry
