I agree with Thomas' assessment here. And to provide another example, while globes are all three-dimensional and tactile in the sense that one can or may touch them, there are globes out there that are designed to be tactile in nature in that, e.g., the continents are raised in such a way that someone who is visually impaired can get a sense of shape and size through tactile means. So, I would only employ "tactile three-dimesional object" if indeed the globe was produced for that means.

I think the clearest definition for when “tactile” is used is found in the note in the RDA-ONIX Framework document for sensory modes (which include touch as one of the means by which the content of a resources is intended to be perceived).
http://www.loc.gov/marc/marbi/2007/5chair10.pdf
SensoryMode
A human sense through which the content of a resource is intended to be perceived.
Note: This attribute refers to a human sense through which the content of a resource is intended to be perceived, as distinct from a sense through which it might be perceived either incidentally or with the aid of an intermediating tool other than one which would normally be expected to be used (e.g., a device for transforming digitally encoded alphabetic characters into simulated voice).
I would take this mean that incidental sensory modes that are not essential to the perception of the content of the resource can be excluded from consideration.
Most three-dimensional objects can be touched, but if this sensory effect is not essential the perception of the intellectual or creative content of the object, then the objects are not “tactile” three-dimensional forms.
An educational object that teaches about textures through touch I would think would qualify as a “tactile three-dimensional object.”

Did we ever figure out the difference of when we use three-dimensional form vs. tactile three-dimensional form?
I would say that most three-dimensional forms can be touched, so there is a tactile component to them, as three-dimensional forms.
Of course, for some things, it is clearly not the intention for the 3D object to be touched. A Brain in Jar of formaldehyde comes to mind. (Go figure!) ;-) I mean, it would be possible to touch the brain, but probably not a good idea.
What about a plastic model of a brain that comes apart in various pieces so it can be displayed, showing the anatomy of the brain -- or the brain can be taken apart, so you can see how the pieces fit together. Would you consider this to be "tactile"?
Curious!
Thanks,
Julie
