### Subdivision not working as expected

Check if you have any overlapping vertices. If you look at the 2 other shapes, they are okay. Select All with A, then press M and merge by distance. Alternatively you may have some "Edge Crease&...

Aim to have the same number of vertices in an edge loop around the inner part of the button,(around the button holes) as you have in the circumference of the rest of the button then use the Bridge ...

### Unexpected kinks in mesh

Its caused by the bevel and subdivision modifier not having enough supporting geometry. Create a Loop Cut like so near the edge

### How to keep a smooth surface with sharp edges when subdiv applied?

Create this topology: Bevel it: Give it Array, Simple Deform and Subdivision Surface modifiers: Also give it a Lattice modifier if you want to make it narrow at its top and bottom:

### Modelling surface diagrams

Is this the kind of result you are trying to achieve? It's pretty easy to extrude new faces (sheets) from a Blender plane that acts as the main sheet. Create a plane (⇧ Shift + A Add > Plane), ...

you have non-planar faces caused by these 2 vertices. All vertices within this area have a Y of -1 but these 2 vertices have -0.99976. Set them both to -1 and the shading problem will go away. Also at ...

### Assigned texture leaking out of the area after aplying subdivision modifier

You can add an edge loop (CtrlR): Or select the existing edge loop and CtrlE > Edge Crease, which will counter the Subdivision Surface effect:

### How can I Subdivide a Mesh into Even Square Faces?

No, you cannot fit perfect square faces on every cuboid. Let's take a simple example: a cuboid with dimensions that are not multiples of the same number. In this case, you cannot perfectly fit square ...

Start with a Plane and subdivide 3 times. Select faces as shown and press i to Inset Faces. Delete the other half of the shape and add a Mirror Modifier. You can easily resize the square with S to ...

### subdivision surface looks horrible

Supporting Edge Loops Needed The pinching you're seeing with the Subdivision Surface modifier on your cylinder can happen when there are no supporting edge loops near the edge between the side of the ...

### Force subdivision surface to pass through control vertices

The slow solution As mentioned in my other answer, here's the easier way, but slower. I use a simulation zone, but a repeat zone can be used instead... Sorry for a big screenshot, but Blender ...

### Force subdivision surface to pass through control vertices

I don't have the time or energy for a full answer, but this won't fit into a comment, and is better than nothing, I guess. The behavior you want is probably how beziers with auto handles work: You ...

### Can you pavé gems based on surface instead of topology?

Here's a GN group that will pack instances on a surface, irrespective of its topology. The packing is based on a hexagonal tiling of its UV space. It relies on 2 subgroups. A hexagonal tiling of a ...

### Two questions about the operation of the Subdivision Surface Modifier

If the modifier is able to smooth the edge of the donut without being applied, why does it have to be applied in order to get the higher density needed for the droopy icing? The modifier creates new ...

### How to subdivide keeping the form of the curve_

Subdivide comes with a 'Smoothness' setting, which appears to need some definition of a vertex-normal to work with: In the absence of faces, normals appear to be derived from vector-to-object-origin. ...

### How to fix shading issue on the topology of the modified cylinder?

The current edge flow of your model does not meet the requirements to effectively support a Subdivision modifier, leading to shading issues. You could try to remodel it like this then just adjust the ...
