I played around with it for a while and here’s what I have found out. The 3D grid tool does absolutely nothing. I cannot get it to work. Maybe, I’m doing something wrong, but it will not work for me at all. That being said, the 3D perspective snap is pretty cool (not the same as the grid at the top). If you go to Snap at the top:
It will make a little useless box like this:
Now, I spent waaaaaaaay too long trying to play around with this box (I resized it, I figured out how to click the box and then plane, and so much more…all completely useless). So here’s the trick to it. Go to your layer’s panel and double click the 3D perspective layer:
This will pop up:
And gives you a bunch of options to do things with. I don’t really find this thing useful, but I’m sure a bunch of you will, so go nuts. I haven’t really played around with it too much yet. I look forward to seeing what you all do with it. (PS you have to click the camera on the left to rotate around the object).
EDIT: I played around with it a bit more and you can do very basic 3D with it, so maybe we’ll see more 3D intense things from this program.

Edit: After you have inserted a 3D Perspective layer, the 3D Perspective snap button means your lines will snap to the surfaces of the selected 3D object.
Insert a 3D layer as above, then add a normal drawing layer above, click the 3D Perspective snap button, and try drawing.
