Lofted surface transition

When creating a loft between two curves, I am not able to control the top and bottom portion of the surface created, I have joined a picture of the part and my IPT file with the problem I got.

 

Thank you for your help.

Daniel P, 

Finally got it with JD's recommandations.

 

Thank you very much.

Don't loft, rather sweep the two profiles, and then shell them to obtain the correct thickness.

Hi Daniel,

please find a sample of the desired part attached. It was build with the 2009 Version of Inventor so you should be able to open it.

 

cheers

Thank you for your solution, but in my part there are three differents sketchs at each end and the top of the part is not flat. That's why I used surfaces to create the curved top.

 

Thank you.

Daniel,

 

I took a quick look at the model. I personally think this can be done easily by extruding a Y-shape profile. Then draft side faces. Would it work better?

Thanks!

Here is a quick attempt.

I think I would use some 3D intersection rails to get it correct.

Your sketches were too complicated for me - edit your first sketch and see how I simplified it.

See attached attempt. The surface looks OK, but I cannot make a solid of it.

Here is another attempt.

I might use this as a guide to start over.

And a variation on Walter's - but I didn't really like the fillets.
