I undertook to do the job for the sake of an elaborate, intricate geometry. This is an eighth to three times thrown at it modifier Symmetry. And the modeling and removal of the sweep cost of laborious work. After this work, I realized that sweep in principle can be removed from the model of any complexity, the more complex the shape, the longer it takes. Any complex form is divided into smaller, simpler parts, any complex scan is divided into smaller clusters.
