How to create a template for 2 contact wires in an overlpa ?

Hello Everyone, 

I'm new in using Power Rail Overhead Line, I already created Templates of a single track with juste one cantilever and one steady arm. However, when arrived into an overlap, I've had some difficulties creating a template with a twin cantilever, I can add 2 Steady Arms but I can only activate one adn if I activate both I have a message " The template was unable to find a solution". Do anyone have any idea of how I can resolve this ? 

PS : I tried to add a new system item with no succes.

Thanks

    There are many reason why no solution is found. You need to have the number of contact wires in/out that matches the situation in the overlap. You must have enough flexibility on the assemblies to allow placement. If you are using 2 steady arms that have a longitudinal offset from the centerline, ie along the track, then you must set a variable and use it as a Y constraint (one negative and the other positive) to the contact wire of each steady arm. This constraint is used to offset the steady arm from the axis of the structure (the reference line).

    By the way, you can "relax structure placement warnings" in the Options to allow placement of structure even it should fail.
