Make a CAD model from data point

Hi Guys,

I'm trying to make a cylindrical CAD solid model following the curve but it was difficult to make cylindrical solid model using center points in Solidworks because it has a error to connect the center points with spline. Thus, I'm looking for a way to make fiber surface following the center and then export it to solidworks. The fiber diameter is 20um. If you know how to do it or there is another way, please email me: [e-mail]. The below is my code. Thank you for your attention. Bye.

Best,
