I'm trying to cut drawers into a sideboard that I'm attempting to model. I've already figured out how to extrude them inwards into the main part of the sideboard, except it has some details on the front and I can't seem to find a way to cut the faces that aren't parallel to the Y axis (basically the sides of the details). Adding edge loops doesn't work because I'm trying to cut in a straight line, and the edge loops are crooked like the face itself. Boolean modifiers and knife project also don't work. This is my first time modeling something and I'm genuinely at a loss here, I don't know what to do.
So your mesh was a little bit messed up, but don't let it discourage you! The distorted bars that run down the front, the mesh on those looks to have been duplicated over themselves. So there were multiple vertices/edges/faces taking up the same space which can cause lots of problems!!
That removed a ton of vertices and cleaned it up a bit.
