I'm trying to loft a wing that I can change the arc on via: Equation driven curve, using driving dimensions. The loft will only work on half the model? I keep getting the error "Guide curve #1 is invalid. It does not intersect the section plane". I've also tried mirroring the loft i.e when it produces half the required model. Does anyone know where I'm going wrong? I'm pretty inexperienced with Solidworks, so any help would be appreciated. Thanks.
I've attached the model below, it's in Solidworks 2013:
