I'm a newbie at blender, i followed Blender Guru's donut tutorial and I somehow messed the vertex and faces in the donut itself and the icing and cannot undo it because when i realised there's this problem, it's too late. There's 2 problem:

  • The blank/missing face in the icing: The blank/missing face in the icing

  • The merged vertex: Merged vertex

How do I fix this topology (if it is the right term) problem. Thank you in advance!

Here's the blend file: https://drive.google.com/file/d/1OMBtuuoT0yJypkvxGr2OglJo2k7zX5Yo/view?usp=sharing

For the icing, turn on Snapping (magnet icon at the top) and select "vertex" snapping style.


Select one of the edges on the side, and extrude it with E until your cursor is over the vertex of the mid-point. Press E to extrude again once more, and snap to the top vertex of the far side. you will see that the bottom is still not connected.


Select the bottom vertex, press G to move it, and drag it over the bottom vertex on the (already exising) icing.

Snapping leaves vertices close together, but does not merge them, so select the whole mesh with A (in edit mode), then press M (merge) and select "By Distance".


For the donut, just select the two topmost vertices and join them with J.


After this, select the diagonal edges, press X (delete) and select "dissolve edges".


Pro Tip - Don't forget to turn off snapping afterwards (magnet icon) - it has caused me many headaches throughout the years ;)
