The sketch I am working on has about a bajillion individual lines (splines) that I would like to combine into more meaningful segments. It seems like a very simple operation, but I cannot figure out how to do it despite a lot of internet and CAD forum searches. Does anyone know how this can be done?
If this were my work I would use the sketch only as reference in recreating a new sketch.
I doubt that any Splines are needed.
I would probably not put the smaller fillets in the sketch but rather as placed features.
Fortunately it is relatively simple sketch...
I started for you (see Attached).
The sketch is made from only lines, no arcs or splines at all. Where did the sketch come from, does the program have any options for exports?

.stl files do NOT contain native CAD geometry. .stl files contain triangulated meshes and, as such, are the least common denominator to represent 3D geometry.
As such they are about the worst geometry to work with in most CAD software and are terrible as a beginner project.
Period!

The facets, or, in your case, the individual lines projected from these facets, approximate a curve, or multiple connected curves, not a line.
Fusion 360 does not have a toolset to re-create on or more curves from these individual line segments, and that is indeed not trivial!
Some CAD tools do have that ability, and try to create one or more "best fit" spline curves through the number of line end points. But that would likely fail on too many short line segments.

have you tried "create mesh section" (in the mesh work area) followed by "fit curves to mesh section" (available when editing sketch created for the mesh section)?
I'll take back what I said in my post about how Fusion has no tools to do this.
I keep forgetting about the mesh section tools 😕
Senior moment here - for some reason I cannot generate Mesh Face Groups on this.
Am I missing something?
Edit: Never mind, I got it if I didn't use Quick...
Seems to work for me. Don't think this will work too well though because the fillets everyware tend to make it difficult to get useful faces. I needed to reduce the angle threshold to get this but because of the fillets the triangles around the flat fate are almost tangent.
