We model a lot of hoses. You can use Xpres Route to draw a straight line framework, and then apply a curve (connecting to mid points, and/or end points of the framework.) Use the curve to define the tube. Adjust the straight line framework to adjust the curve.
Similarly, you can use 3D sketch to build a framework, and then use a curve and sweep a profile along the curve.
Wire Harness can also be used to model a hose if it is set up with hose data.
