When I put you to build a simple plan, such as a wall pile, I can locate it very easily where I want to put it using the x y coordinates. But when I widen that same wall and make a square, it is no longer so easy because it takes the center, as I do to build the plane in the upper left corner, to be able to modify the plan at my whim knowing that I already have it located, because every time I make a modification I change it, for the deconstruction I read that if you can, to build no???
