Thanks for the tip on showing zonelines. If that option were a poisonous snake, i'd be dead
The reason i am using precise loc ranges for zone lines is because i have a zone with a western border and two roads that diverge (in a yellow wood, of course), one that zones to a connected zone on the south-west and the other to a zone on the north-west. Think east --> west commons, but this is more like east --> north-west commons and east --> south-west commons. Granted, i could mountainize the whole thing and use two zone exits, but i want the same effect as east - west commons, an open zoneline. And yes, in this case i could divide the zone in half and put zonelines in accordingly. However, this becomes more difficult with an open zoneline where -7000 < zonelineA < -2000 and a second zoneline where 3000 < zonelineB < 10,000 and the whole zone on this axis is -15,000 < x < 15,000.
