3D transform in 17 Harmony Advanced?

Hey, I’m trying to do a simple project making a 3d cube. Every single tutorial has you go into the layer properties and check the enable 3d box, but my layer properties show no such box to check. The top line under the transformation tab is just the radio buttons under Position for “3D Path” or “Sepatate”.

I’ve got the perspective tab open, and can move around in there, and have had some luck moving layers forward and back on the Z axis, but I’m not seeing how to transform rotate them 3-dimensionally.

Help!

As far as I know, Enable 3D is only available in Harmony Premium.
