Spline modeler Profile not Path?..never mind got it.

Why is it that right after I post something on this fourm I figure it out?
Thanks for looking!
Hey everybody
I've been staring at the Carrara Manual for hours. Studying the spline modeler.
Now I've used the spline modeler for months with simple objects.
But no matter how long I study that manual I can't see how the trumpet or umbrella is created.
Every thing I try comes out as an extrusion path, not a solid object.
In other words I don't see how the profile of the " Leaf" in the manual works.
I can draw a path but not a solid profile of an object.
I'm trying this because I want to change the shape in animation.
I want an arrow that follows a path. I can creat this odject in the vertex modeler easy but I believe
animating it would be a PITA. So I'm trying the spline modeler.
I'm going to doubt I've explained this clearly, but if anyone understands what I'm trying to say it would be great.

If you look in this image from the manual, the right wall appears to be a cross section of the object, not a path.
I just can't seem to figure this out. Both my right wall and bottom are acting as path's. I gotta be doing missing something
dumb.
Thank You
