I have this recurring issue: the knife tool is fucked up because it is snaping to the 3D cursor. Visualy: the green square of the first vertex is located in the 3D cursor.
The tool is therefore useless, nothing is cut. No modeling possible.
I had this issue before, I think I solved it by switching from modeling to shading mode and back. How ridiculous is this. like dancing for rain.
If I start a new scene it is ok, the tool works on defaut cube.
But I cant find how and why in my actual working scene, so bored!
ok, have you check if the snap is enabled ? (I don’t think this would change anything but we never know )
Which version of Blender are u using ?
If it dosent’t change anything, could we have the .blend file ?
Sorry for the laaaaaaate answer, and more than that, I will disapoint you, I’ve being searching for a good thirty-forty minutes and find nothing,
I have the same problem, but can’t find a way to solve it,
sorry and I hope you’ll find an answer
I believe you are right…I can take it and open your file with Load UI unchecked…the very first time I saw the knife try to snap to the cursor but then acted normal…was able to use with out any problems… Opening with your UI active, I could’nt find anything that would cause this nor was I able to stop it from snapping to the cursor when clicking anywhere in the object…Sorry!
You can try re-opening your file and un-check Load UI and see if that stops it screwing -up in your system…only thing else you might need to do is to re-set everything back to the vanilla state…and what ever you like in the settings and re-save as your start-up file. You will keep your add-ons so that won’t have to be re-done…
