What is best way to create? Conical, shell, with cutouts aligned with wall

I'm new to CAD and struggling how best to create this model, though found one way, but looking for advice and options.
- Imagine a short pipe, with consistent wall thickness
- Pipe diameter changes over it's length
- Pipe wall is interrupted, with overlapping elements, enabling flex/tightening with external clamp.
In the attached document I've created profiles of both ends of the pipe, lofting works here. But is there a better way?
I arrived at this method only after struggling with other methods, where I had initially tried to loft two concentric circles at two different plane elevations, that failed (unable to loft with "inner loops"). Instead I created cross-section profile then revolved it. Then with some difficulty created profile of the overlap and extruded removed material, but the extrusion was aligned axially, not sure how to get it to align parallel to one of the pipe walls.
Anyhow, what other methods are possible? Appreciate any help of insight or even suggestions for better sketching these profiles, they also seem "off".
Thanks

Here's one way to do this. Sketch 1 is a 'use' of the edge of the pipe and sketch 2 uses an implicit mate along the line to make extrude parallel to pipe wall. Also see the copy ps done with a revolve.

Thank you. I was not aware of ability to select the mate icon and then choose those for creating/selecting a plane to sketch on. Missed that in the various self-training I've done. Much appreciated!
