Hello all.

I am having some problems with tween curve component.

Here is what I am trying to do.

1. Loft the cross-like crv with couple of standard circles. The loftting is going to be used as the base of paneling. Since paneling needs it to be one single srf, so I need this loft to be one single srf. 

2. However, the cross-like crv is made up with multiple segments, (I could have rebuilt it, but it will give me too many control points) when I type "what" command in rhino, it tells me ,

Closed polycurve with 16 curve segments.

3. So, I need to make this cross-like crv into one NURBS crv. what I am doing now is, 'tween curve' between a standard circle and the cross-like crv.

Problems I am facing:

1: When I set "tween curve" f value to 1.0 and bake this curve, 'what' command, it tells me 16 segments. I am confused, it should be one segment, am I wrong?

2: When I set "tween curve" f value to 0.9--->bake--->what command, it tells me    Closed NURBS curve. This is what I am looking for, except I want f value to be 1.

Attached is the .gh file.

Thank you for your help.
