not technically but graphically
It's hard to explain. I can use Resedit or Mission Computer, and I have a couple good printed out maps (EVN Starmap) to go by. I can make the Syst resources and I know how to set them up so they connect to each other properly so a ship can jump from one system to the next.
My problem is that my little map must have symmetry and nothing on the rest of the map is laid out that way. I have an artist background, so I can't be satisfied with lines that go everywhere and nowhere.
It's probably easy when the map is laid out for you, if say you are following a piece of sci-fi
But what do other creators do?
