Hi everyone,
I am continuing to learn fusion by trying to create models of drawings that are in my 40-year-old drafting textbook. I'm having some trouble with this hook. I have recreated the drawing, but I'm not sure how to make it into a solid. I know the loft or sweep functions should do the trick, but I'm not sure how to make them use the lines I have created. I also don't know why my ellipse fragment (bottom right) turns from black to blue after I trim it down from a full ellipse.
Thanks!

The reason is the halfquarter-baked implementation of the ellipse.
Are all of your sketches fully defined (no blue curves or white points)?
Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?
(I had my students model this Hook for 25 years.)
I could have used Sweep for all of the circular cross section as suggested by @davebYYPCU , but using Loft give you more options on the shape of the cross-section as illustrated by @wersy .
I suggest you try both ways. (Replace my Revolves.)
I seem to have figured out how to do everything -except make that ellipse turn black.
Here is a link to an export of the file.
The more you look, the easier it can be. (one sketch)
Takes some thinking to keep the ellipse constrained. Adding geometry to the ellipse would sometimes unconstrain it.
I broke the Ellipse and made the larger side construction.
Might help...
