Abstract: A simulated panel door structure formed from a flat surface door utilizing an endless groove formed along the flat surface and etched to a uniform depth. The endless groove possesses a base surface and first and second side walls extending outwardly from the base surface. The second side wall of the groove is positioned outside the first side wall toward the periphery of the door. An insert having a lower surface and first and second side walls positions within the endless groove such that the lower surface of the insert lies adjacent the base surface of the groove. The first side wall of the insert lies adjacent a beveled surface of the veneer and extends no further outwardly than the flat surface of the door. The second side wall of the insert lies adjacent the second side wall of the groove. The insert further includes a lateral surface spanning the first and second side walls with a depression therealong.
