I'm having trouble attaching curves to NURBS circles. Basically what I'm trying to do is create a complex shape outline for extruding. I created 3 NURBS circles in the side view in a pyramid formation (2 circles on the bottom and one on top). Next, I drew a short concave curve and attached it from the top of the bottom left circle to the left side of the top circle. I duplicated this curve and rotated it for the opposite side. Then, I did it again for the bottom.

I'm wondering how I would connect all the curves to just make an outline for extruding. Is there an easier approach? I figured using the circles and the duplicated curves would allow for a more even extruded object. Maybe it would be better to just get a better grip on the curve tool and use that?
