1. Select the circle

  2. Shift select the cube

  3. Enter Edit mode

  4. knife project

And it doesn't work

Has something changed? What I'm doing wrong?

  • $\begingroup$ I can reproduce this and it looks like it might be a 2.93.4 regression. $\endgroup$ Sep 4 '21 at 1:42
  • $\begingroup$ Hi :). Selecting in Blender is a bit inconsistent. In viewport it's Circle + shift + Cube. In outliner it's Cube + shift + circle. $\endgroup$ Sep 4 '21 at 8:01
  • $\begingroup$ are they 2 separate objects? $\endgroup$

In Blender 2.93.x you now need to select the object you want to cut the hole in.

Go into Edit Mode Ctrl select the circle in the scene collection and then do Knife Project.
