CETOL 6σ is a 3D tolerance analysis software solution. It enables product development teams to easily and fully understand​ the often complex impact of dimensional and assembly variation on their designs. This knowledge enables them to make adjustments before problems​ appear in manufacturing or, even worse, in their customers’ hands. The cost of achieving a quality product grows exponentially as it moves from design to​ manufacturing and finally into the customers' hands.
