  • $\begingroup$ when you press ctrl and d together its supposed to add a sort of curve. well on thats specific column it freaks out and instead of smoothing out sort of folds on its self. as you can see on the photos instead of curving to it hits the vertices then curves out when its supposed to just curve out $\endgroup$ Commented Oct 21, 2021 at 20:09
  • $\begingroup$ Default control scheme Ctrl + D adds a driver to a property, are you using nonstandard keymapping? $\endgroup$ Commented Oct 21, 2021 at 20:17
  • $\begingroup$ no my control d works fine but the vertices are messing up on somethings in particular. i am a complete beginner and barely know much about blender $\endgroup$ Commented Oct 21, 2021 at 20:30

    $\begingroup$ You can add your blend file to your question. (How to add a blend file) Then we can look at it and see if that helps us figure out the issue. $\endgroup$ Commented Oct 21, 2021 at 21:19

I downloaded the file and inspected the face direction (shown in the pic below). enter image description here It seems the normals around the pinching vertices are flipped around.

If I re-calculate the normals (in edit mode, select all with A, then press Ctrl+N) the pinching seems to go away. enter image description here

Hopefully I understood you correctly, and that this helps.
