Operação booliana

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:

The Union, Intersection and Difference between a Cube and a UV Sphere, with the modifier applied to the sphere and using the cube as target.

This modifier needs a second object to be the target (the second operand) of the operation.

Aviso

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.

You should also avoid any co-planar faces (or co-linear edges) between both operands, those also tend to give issues currently.

Dica

If you have marked your objects to show the edges (in Properties Editor ‣ Object ‣ 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.

Opções

The Boolean modifier.

Operações

Operação

Which boolean operation will be used.

Diferença

The target mesh is subtracted from the modified mesh (everything outside of the target mesh is kept).

União

The target mesh is added to the modified mesh.

Intersecção

Opposite of Difference (everything inside of the target mesh is kept).

Objeto

O nome do objeto de malha alvo.

Overlap Threshold

Maximum distance between two faces to consider them as overlapping.
