my take on your model
see pic below, not sure why 3D sketching
unless its an exercise in 3D
check the model also- I used the original planes
use the rollback bar to inspect the build
hope this helps-
have a good'n kelef

Great thank you!
You've identified a gap in my knowledge.
So, how did you sketch those lines and the spline without 3D sketch? I was using 3D sketch because to sketch most of that pattern off of the front plane, I thought I need it (apparently not).
as your model is not dimensioned,
nor with design brief- very open to interpretation
if possible I would do as below-
1 sketch- using lines and splines(adjusted to fit your original)
1 revolve- around standard axis
try from a single sketch and plane to see how it works
