When entering diameters, use the diameters of the surface along whose intersection the cut has
been made. Usually they will be the inside diameter of the pipe being cut, and the outside diam-
eter of the pipe it fits on. This will also allow for any bevel, if necessary.
In TYPE 4, cutback refers to the distance on the centerline when making two cuts opposed to
each other, for the middle piece of an elbow. If only one cut is to be made, enter 0 or just press for
cutback.
