Sorry Grandtour, you got me on a bad day. I i just associate lots of question marks / CAPS with the flaming type of conversations. As you said, there's no need to perform individual operations on the x,y,z coordinates. Vectors can be added directly, multiplied, etc. Damien explains how the math works very well above, in a very lengthy post (which i guess you missed since you are only complaining about my rudeness and not thanking him in any way).
