So I went to make a half round pole yesterday and I found myself humbled. If I am to learn subdivision surface modeling I am going to have to learn what is different about these meshes.
These Two meshes look the same to me but something is very different about them
I am able to make loop cuts all the way around this half pole and I am able to inset the the top and bottom faces but below shows what happens when I put a sub-dmodifier on them :
It looks PROLAPSED ! so I was wondering if it was due to normals
above if you notice this is the one with the bad topology
Below are normals for the good
So here is the file I am working with

below is a screenshot of this file:
So ya if I am going to be any good at modeling I am going to need to figure some things out. I did some study on poles stars and quads and tris plus ngons. In this example Are we looking at all the mesh or is there something that I need to do to make more things visible ?
Stan-pancakes showed me how to make the half pole the right way HERE
But anyway I am going to need to figure out some things about how to know if a mesh is right.
After making this post I have the idea that I will find info on youtube with the keywords diagnosing mesh problems
