another idea from MC
1. you place 2 temporary bricks to select a area (preferably zone bricks)
2. after you placed the second one a GUI will pop up (i might try make one up if you need further explaining) with 2 columns the left column will be what you want to do with it (see comands at bottom) the other column will be what brick yo want to use
3. you click send, confirm OK what ever the fu@% it will be and it should make building faster
Commands:
Walls: makes a hollow outline without a roof or floor
Fill: makes a solid outline of bricks
Out line:make a hollow cube out of bricks
floor:fills the bottom of the zone with bricks (only 1 layer)
ceiling: fills the top of the zone with bricks (only 1 layer)
