knife project not working anymore

[exelsior4000]

for no reason at all, the knife project completely stopped working for me and i have no clue why. I always get an error message: "No other selected objects have wire or boundary edges to use for projection" , although two objects are selected. It worked perfectly fine a couple days ago.

I'm not familiar with the tool alot, but i only got it to work with planes, circles, text meshes and other 2d dimensional shapes, a cube for instance would refuse to work and come up with this error.

Here's the Explanation for this in the blender manual:
"The primitives, being manifold objects, do not have wireframe or boundary edges. In the case of the cube, deleting the top face will result in cutting edges.

Select Non-Manifold (Wire, Boundaries) will highlight the cutting edges of mesh objects."

So basicly any closed 3d shape won't work, however if you delete a face from a manifold object, that cutout part would become the knife projection.

thanks for your explanation. However, I reverted the version back to 2.90 and it's working again with no issues (even on closed 3d shapes). I guess it's just a bug

Might be related to this in the latest update:

Knife project leaks memory each time a text, curve, or surface object is used for cutting. (T90791)

Yeah, i just tried it on the STEAM version 2.93 and it doesn't work.
Most likely a bug indeed. 2.92 still worked.

I just read it up on the bugtracker. It seeems that knife project only works with curve and text objects now. Not sure if this is going to stay.
