Questions tagged [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: Union, Intersection and Difference. Use this tag for questions relating to the use of the 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:

enter image description here 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 mesh object, or collection of mesh objects, to be the target (the second operand) of the operation.
