Modificateur Boolean

The Boolean modifier combines multiple meshes using a Boolean operation.

Applying the modifier to a sphere and creating the Intersection, Union, and Difference with a cube. The cube is hidden for a better view.

Avertissement

Only Manifold meshes are guaranteed to give proper results. Non-manifold ones (especially meshes with holes) will usually work well, but might give odd glitches and artifacts.

Astuce

If you have marked your objects to show the edges (in Properties ‣ Object ‣ Viewport Display, enable Wireframe), you will see the edge creation process while you are moving your objects around. You can also enable X-Ray to see inside the objects.

Options

Le modificateur Boolean.

Operation

Intersect:

Only keep the volume that’s inside the modified mesh and all of the source meshes.

Union:

Add the source meshes to the modified mesh while removing any interior faces.

Difference:

Cut the source meshes out of the modified mesh.

Operand Type

Object:

The source is a single mesh object.

Collection:

The source is a collection of any number of mesh objects. If the Solver is Fast, the Intersect operation is not allowed.

Object

The source mesh object.

Collection

The source collection. May be empty if Solver is Exact, in which case the modifier simply removes the modified mesh’s interior (self-intersecting) geometry.

Solveur

Algorithm used to perform the Boolean operation.

Fast:

Utilise un solveur mathématiquement simple qui offre les meilleures performances ; cependant, ce solveur ne prend pas en charge les géométries qui se chevauchent.

Exact:

Uses a mathematically complex solver which offers the best results and has full support for overlapping geometry; however, this solver is much slower than the Fast solver.

Options du Solveur

Materials Exact Solver

Méthode pour régler les matériaux sur les nouvelles faces.

Index Based:

Map the first material of the source mesh to the first material of the modified mesh, the second to the second, and so on. If a source face has a higher material index than the number of material slots on the modified mesh, the modified mesh’s first material is used.

Transfer:

Use the same materials as on the source mesh, adding new material slots to the modified mesh as necessary. For empty slots, fall back to using the same material index as the source mesh.

Self Intersection Exact Solver

Correctly handle self-intersection in the participating meshes, at the cost of performance.

Hole Tolerant Exact Solver

Optimise la sortie booléenne pour la géométrie Non-manifold au prix d’un temps de calcul accru. En raison de l’impact sur les performances, cette option ne doit être activée que lorsque le solveur Exact démontre des erreurs avec une géométrie non-manifold.

Overlap Threshold Fast Solver

Maximum distance between two faces to consider them as overlapping. This helps solve the limitation of this solver. If the result is still not as expected, try using the Exact solver.
