Today I've been designing "deck plans" for a mobile factory complex for one of the games I'll be running at Dragonmeet. It isn't particularly complicated but it's BIG - four page widths by two page lengths, about 20" x 35" when assembled. And it's only 1.12mb as a PDF, which is pretty good. Here's a preview:
As usual there's a lot of crud from the jpg compression that won't be in the PDF.
The one I'll be using at Dragonmeet won't be quite as good because I assembled it then spotted some things I wanted to change. But it took me ages to cut and line everything up properly so I'm going to live with it.
