A method of making design models allowing for CAD data verification of interior and exterior styled surfaces comprising the following steps. Initially, the interior and exterior surfaces of the proposed design are mathematically modeled. A series of separable parts of said design are defined. At least one bench mark plane is provided within the interior and exterior surfaces of a first part of the design. An exterior surface is shaped on an exterior portion of the first part of the design. Likewise, an interior surface is shaped on an interior portion of the first part of the design. The interior portion and the exterior portion are separated from each other at the bench mark plane when the interior portion is formed. The interior portion and exterior portion are assembled together at the bench mark plane. Finally, the separable parts or modules are assembled together at the boundaries. The method further allows for the disassembly of particular modules and their modification in holding fixtures. The holding fixtures allow for the location of alternative surfaces of the module part relative to the coordinate system and for accurate scanning or measuring any modified surfaces and further verification of CAD surface data to ensure design intent is maintained.

Refrigerating cabinets of different sizes and shapes may be manufactured by the use of a single positioning member. Thus, the positioning member has a configuration which is adjustable to adapt to the particular shape of a given inner housing of refrigerating cabinet. When the adjustment is made, the performed housing is fixedly positioned on the thus adjusted positioning member. Previously formed outer walls of the particular cabinet involved then are positioned about the thus positioned housing, with a space being defined between the housing and the outer walls. The positioning member further includes elements which may be employed to partially form a foaming jig. This total unit then is moved to a simplified foaming unit, whereafter the formation of the foaming jig is completed, and insulation material is foamed into the space between the housing and the outer walls.

A pin for use in making the reflector includes an elongated snank of regular polygon outline and a cube-corner formation at one end. The cube axis of the cube-corner formation is at an angle other than zero degrees with respect to the pin axis. A group of such pins are assembled into a pin bundle for use in making a mold insert for the reflector.
