Im buliding a wheelchair lift with gates on the entrance and exit. This lift comes in 4 different sizes, which i made family types for. The problem is with doorswing linework for plan views. one of the doorswings will not flex to match the size of the door, no matter how much i try to lock it to surrounding geometry and ref planes. I have no idea why this happened. is there some "secret" to locking linework? plz help.
