(3) Notes

   Note-1 : PRO_FEAT_SHELL

   Note-2 : Shell feature name. 

   Note-3 : Select the surfaces to be removed from the part to create shell
            feature. Multiple selection allowed. This element is optional.

   Note-4 : Default thickness for the shell.
            Should be positive and bigger than zero.

   Note-5 : Select a surface to specify a local thickness value.
            Only single selection is allowed.
            Cannot select any of the "Remove Surfaces".

   Note-6 : Local thickness value for surface selected in Note-6.
            Should be positive and bigger than zero.

   Note-7 : Select surfaces to be excluded during shell.
            Use Lace boundary to specify closure of excluded part.
            Use Alternate cut to specify cut method for extracting interior.
