Abstract: A façade on a roll-up door simulates an object, for example a pair of carriage doors. A plurality of adjacent panels each carries a single panel overlay. For example, a four section garage door has one panel per section. Each panel overlay is fastened to a corresponding panel to form a panel assembly. The panel overlays in combination simulate the object. In order to make the façade, molds are taken from the object. Panel overlays are constructed from the molds. In the preferred form, a plurality of molds, each corresponding to the position and dimensions of a portion of the object having an extent corresponding to one panel on the roll-up door are taken. The overlays taken together provide a façade which is a virtual duplicate of the surface to be simulated, for example a carriage door.
