Hey fellas!

Ive designed a couple of vehicles which I'm hoping to be able to model in Moi. The first one I'm working on now is pretty similar in form to the old Airwolf (at least the main form of it).
I'm fairly new to MoI and I'm having a hard time with this.

The last few days I've tried to create the main form of it using a network of curves and from that use either Loft, Network or Sweep. But I can't seem to be able to get it right.

Would be very happy if someone with some more experience could give me a hint on how to approach such a form

Cheers
Niklas
