Do you have information on how to use connection lines wisely? It appears they are to be used to connect islands of parcels and line points. However, I have noticed some techs using them to connect corner points on ajacent parcels to a parcel that has an origin connection line. I am not sure if this useful. Also can it affect joining? That is if I try to join a new parcel or construction with the second join method to a joined parcel that has connection lines.
