Let me first start by saying that i am very fluent with solidworks, been using it for almost 8 years now. I am having major issues with lofting right now. I need the help of someone is very experienced with lofting and surfacing.

I am making an enclosure for the components shown. There will be 2 shells. The top shell and the bottom. The bottom shell is what i need help setting up. It needs to be one solid flowing piece merging with the bottom. I just cant seem to figure out the best way to go about doing this and its driving me nuts. I am open to any and all suggestions.

Its very difficult to explain what i need to do. The picture of the actual mock up part shows perfectly what i need to model.
