Ok, a couple of instruction videos down the line and I think I am beginning to understand a few more things. Here's the next version of the campaign map. Have I made any progress? I think so. CC3 seems simple enough to get the basics quickly but probably has a lot more subtlety to it that I may well manage to learn later. Hmm, Steve's a CAD wallah. Perhaps I should just point it in his direction and see what he makes of it.
