How to create a realistic rope

say hi to this community from China. my question is how to create a rope or sth alike since apparently we cannot move the vertex(point) in 3D ways like in 3dmax. so what I did was to draw lines in sketch, and sweep the circle alone those lines. but those lines mostly in different planes, the best I can do is to create curves between planes, but the result is not satisfactory.

pls some help here.
