Shrink Wrap Skeleton surfaces in Creo Viewer Lite

[JG_10566827]

Are Shrink wrap skeleton surfaces NOT viewable in Creo View Lite? Is it better to use Stp, iges, etc.instead?
I'm trying to route some piping/wiring on a unit. But NOT having to load the whole unit. Because it seems to slow down my computer. I'm trying to share this with my colleagues via Creo viewer Lite.

Is there an alternative?

What do you see if you turn on the surfaces filter?

I still don't see anything. I've turn on all surfaces filters. I've also have an "active" button. which i also turned on. No luck. I've attached a word document that show what i should be seeing.  The viewer doesn't seem to allow me to turn on the Skeleton part in the Model tree at the very top. 1st part in assembly. That is the skeleton/shrinkwrap part i need to show up. Thank you for your reply.
