The “Knife (exact)” tool is a wretched misnomer. There’s nothing exact about eyeballing the positions of mouse clicks.
What I am trying to do is embarassingly simple. I need to make a cut across a series of faces that begins at a specific edge. Here I made a mspaint art to show you:
Thx I worked hard on it. As for the topic at hand, please tell me there’s a way blender can do this. Btw I tried boolean subtract and it makes a big mess with extraneous edges going in random directions. Not to mention that booleans shouldn’t be needed for something this simple. In the ideal case, I’d like to be able to exactly specify the endpoint of the cut as well, but that may be asking for too much.
