Can someone please help me now?

I tried using boolean on this mesh but it just glitches out…
Any way to fix it? Also tried Bool tool but same result.

Um… Its has been about one hour and still not response???

try subdividing or using a cut tool on the planar mesh to increase the density of it

Looks like you need a cut tool to fix topology or delete face and fill hole

:angry: :angry: :angry:

In that hour you could have done this by hand.

An additional option for quick responses is the #blenderchat IRC channel on Freenode. Let me know if you need any help with that.

Do you really need a boolean though? Depending on how it will actually be used could you get away with just using a bump map?

Depending on the quality of the geometry of the object you’re using to make the cut, I might just bevel the front face of that geometry, delete the depth, and extrude/fill edges from the front face to make the plane.
