I made a tutorial many years ago which demonstrates some of the features in the Loop Tools panel of 3dsmax. PhantomDesign illustrates the answer to your question in his image, but I also cover other features of the Loop Tools if you may be wondering what they can do. There's no narration, this is quite an older vid.
