Solved! by daniel.pinsonneault. See the answer in context.
Finally got it with JD's recommandations.
Thank you very much.
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.
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.
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?
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.
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.
Any progress on this?
