This function allows the user to check the taper for quadrilateral elements.  Taper value is an amount of convergence.  A perfect element such as a rectangle has a taper value of zero.  The user can enter a value between 0 and 1 in the displayed dialog box (default is 0.5).

           The user can include the failed elements in a new part.

           The user can select any element to list its taper value in the message prompt window.
