Sorry to bother you once more. Last week i posted a question here and i decided to post some work. It seems my memory has betrayed me with regard to presenting the z-axis. I mentioned a 45-degree angle with a one on one scale with regard to the other axis. Turns out this is a 30-degree axis with a half-length scale. I don't want to go into the mathematics, and i don't have a question, i just wanted to correct this. Bye.
