Since your new here I don't want to confuse things but I made a sweep macro a while back, it also has a learning curve so maybe something to use in your future here.

:idea:

1) Create a new body to 'construct' the path
2) Use this path via a Binder

But there is a problem between the path and the form : Pipe fail. :roll:

Hi liongate, greetings to the Community!

.... an alternative modeling flow, without using a sweep path, which includes a nested multi "Additive loft" (nested to avoid "unexpected" behaviors of the "Additive loft").

liongate, I didn't have time to process your file but I made a sweep/morph, identifying the Map mode and Support might help you. I have been working on adding Morph to my Sweep macro which should make this easier to do. FreeCAD calls this "section transformation", I call it morphing.

This passes BOP.

I tried two more times with the mixed_curve method. I tried B-splines and elliptic arcs to define the path. Results look good - but it doesn't pass geometry check - which isn't fatal if you are done at this point. I borrowed @Shalmeneser 's spreadsheet.
