how to handle this sheet metal part

hi all

i have shell part as shown in (shell part.jpeg)

and i want to make it as shown in (final shape.jpeg)

RIP is not working properly.....can any one give a try?       (of course i could do it in an indirect way, but looking for simple solution)

Note: i am trying this in Solid works 2008

        we can do it in solid works 2009 where there is a new command called "convert to sheetmetal''.

        but

         i want it in solid works 2008
