I am trying to design a roadbicycle handle bar. The challenge is the shape of the handle bar that goes from X axis to Y axis and to Z axis continuously. I couldn’t figure out a way to do this.

Anyone has any idea? Sweep, loft doesn’t work as these work only for sketches that lie on the same axis or plane.

Part - Road bike Handle Bar

Any help here would be greatly appreciated!🙂

You want something like this? [Lightweight fixie](https://discourse.shapr3d.com/t/lightweight-fixie/19027)  
In this case I used loft with a guidecurve.

I generally use Sweep alone for handlebars or tubing. I rotate the arcs/curves on their pivot points to change the sweep direction in any axis needed.

I agree with @Stephen and generally use **Sweep**. Here’s a quick simple example of using it in 3D space.
