Quote:DUPLO Parts are referenced since LDD 2.3 (Part: 23065, Ball 52mm), meaning that most likely LEGO internally has digital versions of most of their parts since a long time. Other DUPLO parts which are referenced are 71956 (DUPLO BRICKRUNNER, AXLE - which is part of an Assembly I guess), 95109 (LIPSTICK, CORE - also part of an Assembly I think) and 10888 (DUPLO TURN BRICK 2X2)
