Southeast Isometric View, After Subtract
{float}

subtract1 - subtracts the inner box from the outer box to create a channel, using p5 to select the outer box as the object to be subtracted from, and p6 and p7 to draw a box that selects the inner box as the object to be subtracted.

subtract1 <-- subtractH(p5,p6,p7)
