I am creating a scene with different objects scattered around, as if they were laid down on the floor, and I found that one of my objects it not touching the plane (the monkey head in the back).
So I have to move really up close to the object (then at some point the zoom strength slows down, not sure why), spin the scene around so as to be have my view aligned with the plane, then move it little by little.
But it's a Monkey head, so there's the jaw part, and there's the back of the head. So after I align the jaw, I see that the back of the head isn't laid down on the plane, just the jaw is.
So I rotate, grab the object up on the Z axis... then the jaw isn't touching anymore...
And then I thought "wait, there's got to be a simpler way to do this".
