i've never done it before but you might be able to use the trax editor to export and import an animation
take a look at the maya tutorials that come with maya it will tell you something about the trax editor
i think you might be able to see the animation in the hypergraph after some fiddling around? only seen it with set driven keys but you might be able to copy that animation and set it's inputs to the cube
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
