Converting Entities/Projecting Cut Edges

Forgive me if this has been posted already, I've looked inthe forums and its just not jumpoing out at me....... BUT I'm arecent convert to the Solidwork world, so I may not be hip with thenew vocabulary at first.

My question, I'm trying to create a lofted piece inside an alreadylofted shape. However if my "base" (or part piece) is 12" high Iwant my child only 3/4" thk. I'm able to project/convert entity ofmy upper surface, howver I'm having trouble projecting the newprofile that is offset only the 3/4"

Is there a tool that compares to the "project cut edges" one foundin Inventor....?SolidworksParts And Features
