Модифікатор «Булів» – Boolean Modifier#

The Boolean modifier performs operations on meshes that are otherwise too complex to achieve with as few steps by editing meshes manually. It uses one of the three available Boolean operations to create a single mesh out of two mesh objects:


Об’єднання – Union, Перетин – Intersection та Різниця – Difference між Кубом та Сферою UV за допомогою цього модифікатора, застосованого до сфери та з використанням куба як цілі.#

This modifier needs a second mesh object, or collection of mesh objects, to be the target (the second operand) of the operation.


Only Manifold meshes are guaranteed to give proper results, other cases (especially «opened» meshes, Non-manifold but without any self-intersections) will usually work well, but might give odd glitches and artifacts in some cases.


If you have marked your objects to show the edges (in Properties ‣ Object Properties ‣ Viewport Display, enable Wireframe), you will see the edge creation process while you are moving your objects around. Depending on your mesh topology, you can also enable X-Ray and Transparency and see the topology being created in real-time.

Options – Опції#


Модифікатор «Булів» – Boolean.#

Operation – Операція
Intersect – Перетин:

Everything inside both the target mesh and the modified mesh is kept. If the target is a collection, then only the inside of all meshes is kept.

Union – Об’єднання:

The target mesh or collection is added to the modified mesh, removing any interior faces.

Difference – Різниця:

The target mesh, or collection of meshes, is subtracted from the modified mesh (everything outside of the target mesh or collection is kept).

Operand Type

Choose the type of the operand (target).

Object – Об’єкт:

The target is a mesh object.

Collections – Колекції:

The target is a collection. When the target is a collection and the Solver is Fast, the Intersect operation is not allowed.

Object – Об’єкт

Ім’я об’єкта цільової сіті.

Collections – Колекції

The name of the target collection (may be empty if Solver is Exact, which can be useful in combination with the Self option).

Solver – Рішач

Algorithm used to calculate the Boolean intersections.

Fast – Швидко:

Uses a mathematically simple solver which offers the best performance; however, this solver lacks support for overlapping geometry.


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.

Solver Options#

Materials Exact Solver

Method for setting materials on the new faces.

Index Based:

Set the material on new faces based on the order of the material slot lists. If a material doesn’t exist on the modifier object, the face will use the same material slot or the first if the object doesn’t have enough slots.


Transfer materials from non-empty slots to the result mesh, adding new materials as necessary. For empty slots, fall back to using the same material index as the operand mesh.

Self Intersection Exact Solver

Correctly calculates cases when one or both operands have self-intersections, this involves more calculations making it slower.

Hole Tolerant Exact Solver

Optimizes the Boolean output for Non-manifold geometry at the cost of increased computational time. Because of the performance impact, this option should only be enabled when the Exact solver demonstrates errors with non-manifold geometry.

Overlap Threshold Fast Solver

Максимальна відстань між двома гранями, щоб розглядати їх як перекривні. This helps solve the limitation of this solver, if the Boolean result seems unexpected try using the exact solver.
