Non-copper regions and Bounding box are nifty features. Non-copper regions are (essentially) what the CNC router scrapes away from the board - everything except your designed traces, pads and other copper features. The bounding box is pretty much what it sounds like. A box that goes around the boundary of your work.

Flotation circuits were added in 1914. Ore was hauled from the mine to the mill by rail. The company merged with the Nevada Consolidated Copper Company in 1926 and with KCC in 1933. The mine was inactive from October 1934 to January 1937. During part of that shutdown, mine haulage was electrified and electric shovels were purchased.
