A process for the manufacture of a large area sheet metal part, in particular a body component for a vehicle, from a flat blank, provides that one sided pressurization with an active medium in a forming tool gives the flat blank a prestretched preform, and that then the preform, removed from the forming tool, is formed into the final shape in a separate deep drawing tool.
