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.
