barron The "Auto-Connect Navigation" setting (located on the Map Tools tab, shortcut key of "U" to toggle on/off) should help out a lot with that, as it attempts to automatically connect navigation paths to any adjacent tiles as they are being placed into the map. The tiles need to be configured as "Passable" in the Voxel Editor for it to work. The logic it uses to make the connections isn't perfect, of course, but it should at least take care of most of it, and then small adjustments can be made to add or remove specific paths as needed.
