Thanks, yeah I tried to use no shortcuts and just tools that could be understood by just watching the video.
It’d probably be better to use a Solidify modifier after extruding the circle on Y. It’ll give you less wonky topology.
I agree I am still a beginner, but compared to two years ago when I would uninstall Blender every other week, I feel like I know how to do most things I need now.
I just pushed the prop I created into the floor, and no one will know but me.
I will try all your suggestions when I get some time. For now, I have the prop I needed.
Thank you all for your replies.
Okay, here are the steps you need. No Subdivision or Booleans. Don’t complicate things. This is easy to model. I know you already have what you needed, but really, everyone here is making this way too complicated. You don’t need any special tricks to make this. Give your circle enough verts to begin with.
Faces - Inset Faces
With the center still selected, delete only faces:
Delete these faces (delete Faces this time, not Only Faces)
Extrude these faces:
You’re done.
Simple.
Oh, I just noticed it’s not cut off right in half. Cut off the appropriate amount, turn on mirroring on the Y. 
Rotate that edge
THEN extrude Faces
I never noticed the Vertices on Add Circle. I will look for that next time I play with Blender. Thanks
That’s what mostly everyone would advise you do. 
Yes, it’s easy to miss this. The dialogue box isn’t presented BEFORE you create the circle. This is, in my opinion, an unintuitive UI design in Blender. As a beginner, you wouldn’t know it’s even there! I didn’t know about for the longest time. And as soon as you do something else, it goes away. If it ever disappears before you’re done with it, press F9 to bring it back.
Here it is, way down in the left hand corner of the screen, after you Add something, actually after any command that has options. Have you ever seen this? Did you know it existed? Probably not.
The F9 key brings it up wherever your cursor is at the moment.
There is no need Undo or type Enter after entering the numbers you want into this box. Your circle, or whatever it is will change in real time.
For future reference, that’s called the Adjust Last Operation panel, and F9 to bring it back only works until you’ve done another operation; eg it works after you created a circle, but if you move that circle, you can no longer adjust its parameter, the ALO will then show parameters for the move.
I agree it’s not intuitively obvious, but once you know it’s there and how it works (on anything that’s an operation, an immediate action, rather than a tool), it’s super useful; I use it extensively.
As a beginner, it also helps to read the fine manual, often, and in small chunks which one should practice right then and there so the reading has some immediate practical application. It could be better, it could in particular use more examples, but it’s this sort of thing one can learn from the introductory sections about the interface. Blender is a complex piece of software, one can’t really expect to learn it by osmosis.
nice to know F9 brings it back… i’ve had that bugger disappear on me for no reason (i didn’t do anything following that i know of).
Thank you, the F9 explains why I had never seen the Circle properties panel. That is good to know about the Last Operation, and yes I agree it is a buried, hidden feature. I think a nice feature that would help most Blender users, is after they perform an operation, show a little box explaining this feature with a ‘Do Not Show Again’ option to hide it. Blender is an app you could use for a lifetime and always find new features.
Thanks again.

Actually this pops up when you do some new operation if enabled via View → Adjust Last Operation… and i even think this is the default… ( ← but i’m not sure about that… )
So it is present WHILE creating things… adjusting the last operation (here create a circle…)…
…maybe the nameing is somekind of unfortunate because if you do a new type of operation then the last one is the actual one… but after this it memorizes the parameters of the last one…
…so again the user can choose…
- popup every time to manipulate the (maybe memorized) parameters…
- or just repeat with actual/last parameter and call it only if you need it via F9
… i just imagine how this should be more intuitive or a better workflow if you have to confirm the parameters every time BEFORE the actual object will be created… 
Yes, I guess I didn’t explain that well enough. If you do move it or something, just undo, go to Undo History in the edit tab go back to before you created the circle, and do it again.
The thing about it is, whatever you are doing, it’s going to be wrong the first time. It’s not going to have the settings that you want, because it doesn’t give you the option of entering the parameters you need before you press ENTER and do the thing, whateverit is. You have to do it wrong, default settings, first, and THEN, adjust the the settings to what you wanted in the first place. Why are we doing this? It’s built in to the software. Why would anyone design software this way, on purpose? This is a huge waste of time. It really is, especially if your computer isn’t the latest greatest with the best GPU available. When I’m working on something that’s high poly, it can be slow as molasses and frustrating, and my computer isn’t a potato, it has two Xeon processors. I love Blender, it’s great, and powerful and amazing, but come on, it could use some improvements. End of rant.
The F9 key was a HUGE help to me. Someone on this forum told me about it. I’m glad I could be of help.
Sometimes it either fails to pop up for me, or it just disappears so quickly you never would have known it was there. Sometimes it pops up and stays there like I want it.
Don’t know why. It’s annoying, but not something that keeps me up at night. One of those “lovely joyful moments” of blender’s operator architecture…
I meant I moved in Omniverse. I created the prop using Booleans, and don’t feel the need to recreate it at this point. I was hoping there was a simple solution for what I already had.
Could it be there is a difference between windows and blender ?? For me after enabling it (or is it default?) it is just there.. 
So because i’m used to it.. maybe i’m biased about the “findability” of that feature.. at least i think i would wonder the first time where to change the amount of vertices, search for it and then never forget such a essential feature.. i can’t imagine users only using cylinders with 32 vertices on the border for very long..
Ohh yes.. 
.. i’m so used to it that i do not noticed that the very first time it pops up it is folded.. but after unfolding it then it pops up unfolded.. (and after folding it it pops up folded.. )
( or.. even a bug under windows ?? .. sorry.. i didn’t mentioned mac 
)
hmm… well it is mentioned very early in the basic explantion about the docs.blender manual interface /window_system regions.. and even mentioned in docs.blender manual editors preferences system:
Global Undo
…Warning
While disabling this option does save memory, it stops the Adjust Last Operation panel from functioning..
Maybe it should be moved/ additionally added to the N-Panel → Item ?? But then i remember people complaining about the Transform → Location, Rotation, Scale setting to being “double” in Sidebar → Object → Properties and N-Panel → Item..
IDK..
I use the BSMax addon… if I want to edit vertices next week, yay… i can edit them… i hardly ever actually use Blender’s default primitives. Maybe the cube and plane, that’s about it…
Well… i know of this MAXimizing 
addon but didn’t bother… because… somekind of unfortunate adverting ??
The goal of UI simulator is people that came from other software (like me) feel comfortable…
→ UI simulator… i didn’t want the UI… 
( didn’t read this before on GIT … just somewhere else…)
Didn’t know it also provides some other things…
Still… i found this usefull…
Yeah, I don’t use any of the BS Max user interface modifications… Just all the nifty tools themselves.
Nice link with that wonder mesh, I’m going to have to check that out.
Just realising it also maybe this one (from 2020 the other from 2018 … ?? )… even if named ..28x… i use it even in Blender 3.6.4
