Blending the last part of a model

[Alfredo94]

Hi, guys!

I have this CATIA model I'm working on for school, but I'm having some problems when blending the last part to thicken it.

I really hope you can help me (any suggestion will be trully appreciated).

Thank you so much in advance. Attached you will find a screen shot of the problem, and here you can find the CATIA file.

I guess you've already tried splitting the surface to that last section and trying a Thick Solid?

If that doesn't work, I would try to make a Multi-Section Solid to fill in that section. I'd make two sketches, one of each end based on the solid faces, plus I'd impose tangents to both solids. I'd also use the yellow curves as guides, and the white curve as the spine.

If I didn't like the solid, I'd try again with a Multi-Section Surface for more control.
