Hi Guys,
I have a prison cell I’m trying to make. I started by subdividing one side and then removing some surface to create a window. Then I tried to subdivide the rest on other sides, but it doesn’t work anymore, and the center orgin has shifted.
If you look at the selected surface, the origin is about 75% to the right instead of 50% dead center.
It’s really annoying!
Plz help and see the attached pic.
Thanks!

That face in question is a ngon - a face with more than 4 vertices.
If you subdivide a triangle, you get four triangles. If you subdivide a quad, you will get four quads.
But if you subdivide an ngon, you will only get another ngon, because you just increase the number of vertices around the edge, but not the number of faces.
By your isolated subdivision of a single face on that cube you created those ngons on the adjacent faces. It might have been easier to create the geometry for that window by just adding four edge loops (Ctrl-R) as indicated here:
Ahhh! You are right. I forgot about the edge loops. I see people using those all the time. I guess that is what I should try first when trying to create new geometry.
And that clears it up a good bit. I see now that I created more vertices on the edge of the other face, which makes sense to create issues when trying to now subdivide.
All in time!
Thanks!
easy ways to controll faces like that is using F and J. F creates a face in between selected verteses (makes an edge of two verteses are selected) and J will make an edge between two verteses i there is a face there already.
if you use F across a face, then it wont work. since you will have ONE face, and one edge overlapping it. if you use J instead, then you will have two faces connected to the edge…
basically use F and J 
i use those a LOT when i model.
in other words, Control R, F, and J.
I… You forgot I key :D.
