i have pretty complex model but it is constantly refused because of thin wall even i designed them as details. At least i consider them as details. i am doing it for silver. min wall: 0,8mm min details: 0,3 mm Can someone explain me how to differentiate them? where is the "line" between wall and detail? edit: i found this explanation from Dragoman on forum, but is there official definition or this is true? "A good rule of thumb is that if the extruded part is higher than its width, it's a "wall", if it's thicker than its height, it's a "Detail"."
