help with filliting in fusion360

[charlieuk]

I am at the very early stages of trying to learn fusion360 and I am trying to draw a mould for a part that uses a air foil. I have got the basics done but I am struggling to find a way to fillet and blend the centre foil part into the ends. I have spent a few days trying to play with the fillet tools but not had any success and tried you tube but not had much luck. If any one can give me any tips or lend me a hand it would be much appreciated.
