Beginners question regarding a simple shape!


I’m sure this is something simple but can’t figure it out. I am trying to draw a basic ‘C’ shape in Blender 3.0 but when I apply the subdivision modifier, it fills the center part of my C. How can I stop this from happening?


A mesh is made up of polygons that consist of:

Tris : faces with 3 vertices
Quads : faces with 4 Vertices
Ngons : faces with 5 or more Vertices.

What you have there is a mesh with a lot of vertices but consists of only one giant Ngon so basically one face.

What you want to do is this:

  1. Start with a circle
  2. Select all the vertices and press E to extrude and then press S to scale inward.
  3. Click when you are happy with the size, Press C for the circle select tool and select the vertices you want to delete. (You can change the size with the mouse wheel, middle mouse deselects)
    4.Press X and select vertices to delete the selected vertices.

Thank you so much. I thought that was the case regarding the quads, so I previously selected them in 4’s and hit F to create a shape that looked the same as you have in your image but it didn’t fix the issue! So assumed it wasn’t that… Anyway I tried what you said and it worked perfectly, thank you for taking the time to reply, it’s really appreciated.
