Just the 3 single lines to create 3 "surfaces"??
The extrude function will select the entire closed (or open) profile.. You cannot select one segment.. So..
Create a new sketch... Project one of the lines... Extrude (surface option) picking only that projected line.. Circular pattern to create the other 2 would work. or repeat the sketch/project/extrude to create the other 2 if its not a pattern.
What exactly is your Design Intent, what are you attempting to model?
Are you following a YouTube video or reading a 2D detail drawing?
Any photos of similar real-world part?
What version of Inventor are you using?
Can you Attach your *.ipt file here?
How are you arriving at dimensions?
Measuring with calipers?
How much 3D CAD experience do you have (I am guessing this is your first project)?
Can you Attach a photo looking directly down on the wheel and another photo looking directly from the side (as best you can)?
Does your company manufacture these wheels?
If so, can you get images of just the metal part by itself?
In your original image it appears that you have the spokes at 120°, but in this image it looks like 90° T shape.
What is the true Design Intent?
I am not modelling that steering wheel exactly, so the dimensions are slightly different. All I really need is to raise the ends of the metal bits a little bit.
I do blender, but the thinking is very different.

Can you model the geometry that you want in Blender and save as *.stp or *.stl and Attach the file here?
I would do a simple Revolve, Trim and Thicken, but I would like to see what you are after first.

That is a simple revolved shape with cutouts.
Hi! To model the exact geometry, it is actually tricky. This is because the actual part was made by non-linear deformation. This kind of steering wheel is probably started with a flat sheet. Then make the cut. Lastly bend (or punch) with a cylinder. I guess the closest modeling feature would be Loft.
Many thanks!

You are right. Revolve gets something close though I think.
Your Wheel.stl is not symmetrical.
See Attached for one example.
