I place an object such as a cube into the scene. I select the cube and press cmd+end. It doesn’t snap to the “floor” of the grid. Why? I’m expecting it to do the same thing it does when you press end by itself for objects above other surfaces. Those objects then slam to the surface of whatever it is hanging over.
The keyboard shortcut for snap to grid is cmd+end or ctrl+end for Windows. This doesn’t work.
