Cylindricity – Can you use Material Modifiers?

WebCylindricity is the 3D version of roundness. It assesses how closely an object comes to a perfect cylinder, meaning that it is not only round, but also straight along its axis. The simplest example that demonstrates the need for cylindricity is a pin which is required to pass completely through a bore with a tight diametral tolerance. WebCylindricity specifies the roundness and straightness of a form. When measuring cylindricity, you are checking for distortion in the cylinder, to verify the accuracy of its cylindrical form.
