view now. Much better. For faces, the multiple slices are actually pretty important. So important even, that I have decided we should have these slices on separate layers. Thankfully, I chose to color so rotate the rest as well. And just like with the cube, we do this for all slices… Eventually, if you have the top slices rotate every frame with 15°, you should be able to make a turn table, like this: (you can snap them with the Shift + S shortcut): Add the top view as well: if you do this for all slices, you get something like this: Using the parallel rulers, you can then figure out the position of
