I don't use Inventor, but I've never run across a seam like that appearing in Solidworks. I'd venture to guess that your sketch is wrong, however. It appears as if there's a divet or depression at the top of the dome which ought not be there and the edges at the lower sides are not perpendicular to the bottom as you'd expect from the drawing.

Can you show us the sketch with dimensions? I had no trouble creating the dome in Solidworks, as Elgin has done.
