You are missing a workplane and sweep profile as far as I can see. See attached.
I did a sweep of the 3D Sketch, then mirrored it.
I don't believe I am missing anything. The preview looks just like what I want, but when I select OK it gives me an error. I am actually on 2010. I know I can't save back to that so the models posted don't help me. I need other feedback of what I am missing. See attachment of preview.
Actually, all I had to do was change my profile to a full circle instead of the partial like I had and it now works. I still don't understand why I had to do that though. I have done other similar ones without having to do that.
