Geometry disappears when using SnappyHexMesh with multiple blocks

Hey Foamers,

I am facing a problem with my mesh.
I want to simulate a 3d swept wing in a box. The box looks like in the attached picture.
It consists of 3 boxes (upper, middle, lower).
If I run snappyHexMesh I end up with a smaller box outside my stl file (photo also attached).
I don't understand where I went wrong.
Do I have to enter multiple location in mesh points or do I have to merge the patches of my blocks in blockMesh?

Thank you very much in advance for your help!!!!!!!
