AutoCAD Inventor :: Lines Aren't Showing Up In Drawings

I needed to make a dome-like feature and the only way I could get something that looked even close to what I was modeling was to use the loft tool. I've attached the model of what I'm talking about (it's Inventor 2010) The problem is when I try to make a drawing for it, it won't show some of the lines on the dome feature. The only way the loft would work was if I checked the "closed loop" button. I tried checking the box in the drawing saying show tangent faces or something like that and that didn't work either.
