How to make a "rope" like object with even width throughout the whole object? (image inside) I'm modeling a cord, but I've run into a problem. Basically I modeled it by starting with a cylinder and rotating the final edge, then extruding that to the next sequence. However, this will cause the width to shrink where the edge turns. It's only by a little, but I would like even width throughout. Truth be told, when I add the subdivision surface modifier it becomes indistinguishable to the naked eye, but I would still like to do things "the right way" if there is such a way.Here's an image of my cord minus sub surf modifier.
Probably the most common solution to this problem is to create a Bezier curve and use another Bezier curve (often a circle) as the Bevel Object (in the Bezier > Geometry properties).

Your question is almost a duplicate of Make a 3D tube with a B&#233;zier curve? .
