Hello pals, I'v got a problem with this model, i have to close the surface to make it look like the attached image and i dont know how to proceed, i've tried to make a bluesurf and use the lateral curves as guide curves but i get errors, thanks
From just 1 picture it is very difficult to understand the shape of that component.
A complex part is composed by small simple geometry elements so I would first try to observe the part from any angle to discover such simple geometry.
What I see (with just 1 picture) is 2 section easily made by 2 shape connected with a loft.
Once you have made that you can proceed to difine the little details.
