  • $\begingroup$ You either need to select 2 objects, or you need to delete the faces (X (Delete) > Only Faces on your cutting object. I guess it's one of these problems $\endgroup$

  • $\begingroup$ I've tried all this. I have used knife project before & it worked. But it isn't now. $\endgroup$ Sep 6 '21 at 15:20
  • $\begingroup$ So it may be a bug as Marty says $\endgroup$

Knife project has changed in 2.93.4.

The new method:

  • Select the destination object in object mode. Do not select the cutter.
  • Enter edit mode. (Shortcut: Tab)
  • Select the cutter in the outliner (or by Ctrl–left-clicking the cutter).
  • Perform the knife project.
  • $\begingroup$ But Why? (rhetorical) That's really inconsistent with Blender's notion of an 'Active' object or selection everywhere else. It seems nuts, to me, until I hear a justification. $\endgroup$ Sep 10 '21 at 9:25
  • $\begingroup$ It's not listed in the changelog, so I suspect it really is a bug. If I get time, I'll look at the git repository to see if I can figure it out. $\endgroup$ Sep 10 '21 at 13:48
  • $\begingroup$ Ahhh.... Sorry, no trouble intended. $\endgroup$ Sep 10 '21 at 15:19
