sweep along a path and tangent to a surface
Hi. According to the figure, a set of yarn is woven on the surface of a cylinder to pass over each other from below. I want to model these yarn in SpaceClaim. I have drawn the equation of the path of the yarn. I want to consider an ellipse cross-section for the yarns and sweep them along the yarn path. But I do not want the cross-section of the ellipse to interfere with the cylindrical shell. If the cross-sectional area is circular, there is no problem, but when it becomes an ellipse, it interferes with the surface of the cylinder along the way. How can I sweep the cross-section of the ellipse so that it is tangent to the surface of the cylinder?
