Thanks Bruce, Those templates are immensely useful. I looked at them some years ago but at the time did not know enough to understand how to use them. A fresh look has got me up and running with a significantly better rendering of 1:5000 scale. I will probably spend far too long playing with them now rather than actually drawing anything new to be sure I have things working in my scraps properly before I spend a load of time drawing up a load more.
