First off..did something change or did I not notice this before. I now get w1, followed by the x y and z co-ords. What is w1? The facet? As for the new use for my sextant. I recently I took down some pavers in a decorated and customized area only to find I needed them back. In the past I would go to the first floor, drop a paver where I think it needed to be and raise it up. But thanks to the sextant I can easily tell which square to drop a paver on to raise it up to the next floor. The rest of you probably figured this out already but this was new to me.
