I have been stuck here for a while and I couldn't figure out why the knife tool is not working on some parts of the mesh.

This will clear a lot of confusion for me so please help me out here. Here is a video showing the problem : https://youtu.be/bjkp75bwdos

Thank you!

  • $\begingroup$ I actually removed that part and started over again, seems to be working as intended now but I am sure I will face this problem again. I was thinking there is some obvious reason why the knife tool acted that way. $\endgroup$ Nov 7, 2022 at 15:46

    $\begingroup$ On the video when you cut the top face two edges appears till the side of the disc. This means the middle face covers the whole area of the circle so the smaller faces on the side are overlapping with it. Probably Blender can't choose which face you clicked on. Take care to avoid overlapping faces. $\endgroup$
