Subdividing

Support Modeling
1

I am using trying to Subdivide a Cube before beginning my Modeling.

I have to Subdivide the Top once, and the Front face a few times.

Select a face Subdivide it works fine

When I select the other face to subdivide, all it does is adjust the face center dot of the surrounding faces towards the face I am trying to subdivide…

I’ve performed this task before without this problem, I never change settings except Blender to Cycles… I am having this issue in both Blender and Cycles.

There must be a setting that I am missing, can anyone identify this issue for me?

How am I creating ngons rather than quads on a square?

I’m starting this project over because I was trying to subdivide after my modeling and I simply couldn’t

Enableing Tri/quad disrupts the other face i have to subdivide…

I just want to split the Top into a 4X4[sub twice… accidentally said once above]
and subdivide the front face 4 times in a square,

without changing the the grid on the sides, back and bottom

You are creating n-gons by subdividing the top without subdividing the other sides as well. Basically you subdivide the top into squares, but all adjoining faces share the terminal ends of the squares in the middle. In other words if you divide the top in to a 4x4 like you said, along the top edge of your front polygon you just added 3 verticies, making a polygon with 7 verticies and 7 “sides” = n-gon. Incidentally this is happening to all other surrounding polygons that are attached to the top polygon as well.

It is better to subdivide globally or to make loop cuts and eliminate unneeded geometry later. A little more work in the end pays off.

Select the front and top faces, subdived them to give the 4 x 4 grid.
Select the front faces and subdivide them again however many times you want.
If you get cuts on the side faces you can leave them as they are or select the side faves and make one single ngon with F
