EDITED

the in place family sweeps I picked to follow model lines are not moving - I picked the model lines as the path, but the path doenst update when the model lines move? can this be fixed.

And in place families can appear to show things in 2 different locations, depending whether you move things in edit family mode - this is possibly the most confusing thing I have ever come across on any cad system I hate it with a passion, please get rid of it
