I am not sure what the story is about that aspect of (PCB) components and footprints. According to SDK documentation (released more than twelve months ago, and thus no longer data of a confidential nature) (PCB) Component objects have a Height property. That property is not changable or viewable, per se, from any standard dialog boxes, and while I have yet to experiment with that aspect of components while using the SDK files, Ian Wilson has previously made a post (I can't remember the exact details off-hand) which suggests that that aspect of components is not entirely flawless. I have not really experimented with the 3D viewer much myself. When I did try it out on one occasion, my PC crashed at the time... Perhaps a really fast PC (or the right type of display card) helps, but I have found updates of views to be very.... very... slow....
