Here is a fairly simple sub-sector that I drew up using CC3 with the Cosmographer add on. Its still a work in progress but it shows how easy it is to create a sub-sector map with CC3. This took all of an hour, and could have taken less time if I knew where i wanted things before hand. Of course, generating the sector on paper before hand took a bit more time than that, about 3 hours all told. For an afternoons work though its something that I’m pretty happy with.
