In Revit you can export to AutoCAD. If you have the right object enabler installed in CADWorx (I think MEP) you can view the objects). However, the CADWorx 2D rep command doesn't always work on custom objects, so I recommand exporting to dumb solids which will print/2d rep correctly. If Revit has a CIS/2 export, that would be the best way to go.
