could any one use the part is build by self?

I just follw the Solidworks help to build the part , but couldn't be use on routing,

could any one have the solution to fix it?

the below is from SolidWorks Help.

You can create an axis in a fitting, such as a valve, to control the angular orientation of the fitting in a route sub-assembly. This axis must be named Vertical, and the axis must be perpendicular to the route passing through the fitting. When you insert the fitting into a route sub-assembly, the Vertical axis is aligned to the first construction line drawn in the 3D sketch at the insertion point.
