@mark -sorry, we've hijacked your post to debate something your probably not interested in. anyway, back to regular programming-

Yes, the original edge was corrupt. I couldn't do anything with it. Any operation gave me an error.
I create broken models all the time. It comes from free-handing. I usually fix them by undoing to before the problem but it wasn't feasible in this case. (I consider broken models to be "bugs" of F360 but in other threads I have been told it is my fault).
It's hard to say what made that edge "corrupt". this model looks like it could have been split and half and reassembled (badly) at some point-

close up of 1, showing short non-tangent segments on the face. I don't know what operation you wanted to perform here, but this would cause filet (and other things) to fail-

close up of location 2, illustrating odd geometry, and the reason I suspect it was split and re-assembled-

As I was trying to duplicate an existing edge I thought the more the merrier.
When drawing splines, more is not the merrier. You end up with a wavy surface.
As a beginner I am assuming you mean to delete control points. Otherwise I don't know what deleting segments means. I clicked on dots and deleted many of them but no profile appeared. You showed a menu (with tabs of Objects and Parents if I remember correctly) with items circled and said to delete, but I don't know how to bring up that menu. I have seen that menu at seemingly random times and have tried to play with it but it never seems to do anything.
No I meant the segments that had been auto projected from the face (I originally thought you had drawn them). If you hold the left mouse button down, it will show a list of everything under the mouse pointer. you can then scroll through the list and pick the thing you want. Useful in a multitude of cases.
here it is showing that invisible projected line-

META: Not letting me see the thread while creating a reply is a major pita. I can't refer to users or things shown to me because I don't have perfect memory. The hint telling me to use @ is useless since the list it brings up does not help me figure out who to reference.
yes. agreed. My current workaround is to duplicate the tab first, so I can switch over to it for reference. not great, but something.
...Try to offset the thin face around the whole object. You will get error saying something about not being able to delete a fillet. There are no fillets...
there are some very small arc shaped faces that it is interpreting as fillets,
... I assume the edge is broken by slight misalignments caused by free-hand operations I performed in creating it. This happens often to me. I have been told in other threads I need to change how I work. I personally feel that this should not happen and is due to some bug(s) in F360.
yes, probably the free hand operations. I think it's less a matter of changing the way you work, and more a matter of understanding what is happening. Fusion isn't a free form modeler. It's an engineering tool that's used to create rather exacting geometry that you wouldn't be able to achieve in a free form way. That's one reason why it's less forgiving when things aren't exactly right. but you can still do things in a free form way, but you would need a deep understanding of the ramifications of the resulting geometry to be particularly successful.
That said,I would still suggest changing your approach. You can achieve so much more, so much faster, once you drink the cool-aid and model in a way that keeps fusion happy.
what operation is it you where wanting to perform on the edge of that part?
