A method for progressively making a model of a sheet metal assembly composed of several connected sheet metal panels, or a model of several interfitting sheet metal assemblies. Each sheet metal panel is represented by a carbon fiber sheet formed between a pair of blocks machined to form a cavity corresponding to the thickness of the sheet metal. The thickness is initially represented by a wax layer corresponding to the thickness of the sheet metal. The wax layer is removed and replaced by a carbon fiber epoxy-based material. One of the blocks is then used to form the replica of a second panel of the sheet metal, adjacent the first panel. The process is repeated until replicas of all panels have been made. The carbon fiber replicas are attached to one another to form the completed model of the sheet metal assembly or a model of several interfitting sheet metal assemblies. The machined foam blocks may be used as tooling aids for forming dies for stamping the sheet metal components.
