help please cant get it right

Ok so i drew this in autocad then imported it into fusion and now in the setup it says my models dia is 4.78" but when i check it in the design section and in autocad it is 4.5" also, i can not seem to get the model to be in the center of the stock. I am making these from 4.5" aluminum round stock. Later i will probably go to 4.75" stock but for now i need to make this work but it is not working like i want it to and I have no idea how to fix this problem.  i want my wcs to be in the center of the part with Y axis pointing straight up to a hole.

In my latest instruction I said 3 circles.

You drew 4 circles.

Delete this circle.

I saw the one where you said draw a concentric circle tangent to the 4.5 circle..

Well you are experimenting with different "solutions".

Click on image to enlarge.

Create a circle by clicking on the vertical construction line somewhere below the Ø.2 circle and Tangent to the Ø4.5 circle as shown.

Trim the new circle as shown.

Add the R.465 dimension.

thank you I now have the posts set to newest to oldest so I now should see the correct solutions.

I told you to Trim the circle too early, but that is OK, because now you get to experience Extend.

Click on image to enlarge view.

Create Ø3.5 circle at Origin and then Extend the ends of the R.465 arc to the new circle.

If you really want to get good at parametric modeling - it is useful to learn to read the Timeline and reproduce the work done by others.  (Or even yourself a year down the road and you forgot how you did something.) Think of the Timeline as a "recipe" for how to bake a cake. 

Examine the Attached file.

Drag the playhead back to just after Sketch1.

Reproduce Sketch1 on your own.

Drag the playhead to just after Sketch2.

Reproduce Sketch2.

Drag the playhead to just after Extrude1.

Reproduce Ext....

...you get the idea.

Ask questions if you get stuck on any step.

(BTW - these are exactly the same steps I would have used in AutoCAD.)

Thanks, that was very helpful. I do have a question about sketch #2. so to draw a sketch on that part like you did I just have to pick the same plane? because this brings me to my other cap just like this but flat.. see picture attached. So basically I can just change sketch 2 or draw a new sketch to make the new cap? This other cap is not really flat, it has an ever so slight radius from origin to the top fillet then straight wall down to the flange where it gets another fillet.

I edit the Sketch2 and a couple of other things (looks to be thicker, and fillet and chamfer).

So where the first one took 10-15 minutes, the revision took 2-3 minutes.
