Modeling 737 Engines

[aeroeng01]

Hi,

I'm trying to model the basic form of the 737-500 engines using the 2D plans from

Link

I was trying to do it by using the front view as a basis for a closed spline. And then the other views to produce guides that I could extrude the first spline along. The swept function seems to do what I want, but it's limited to 3 guides.

Is there anyway I could get it to work with 4, or do I need to use a different tool?

Thanks
