Claim:
1. A method for producing a design in a garage door section, the method comprising: feeding an undeformed planar front surface of the garage door section into a stamping die having a crescent shaped cross section, wherein the planar front surface is formed into a façade cover of the garage door section; affixing the garage door section onto a bed press at a first defined location; and pressing the stamping die onto the planar front surface of the garage door section, thereby forming a first depth variation section having a deep draw portion and a first depth variation portion in the garage door section, wherein the first depth variation portion is formed having a bottom wall having a continuous crescent shaped smooth transition from an undeformed portion of the planar front surface of the garage door section to the deep draw portion, wherein the deep draw portion includes a first substantial right-angle transition from the planar front surface to a first side wall of the first depth variation section, a second substantial right-angle transition from the first side wall to the bottom wall of the first depth variation section, a third substantial right-angle transition from the bottom wall to a second side wall of the first depth variation section, and a fourth substantial right-angle transition from the second side wall to the planar front surface, and wherein the first depth variation portion is surrounded by the undeformed portion of the planar front surface of the garage door section.
