Hello @Swapnil_More ,
so far I see the 3D Model view is not really related to models of the PTC product familiy but is a viewer based on the three.js technology - and it does not use the thingview libraries. This means that it could display the general formats what we can see in the metadata.xml where we can find the three laoder which are used there. So I think it is the same functionlaty shown here : https://threejs.org/examples/
I do not think that there is a direct functionality of showing some live data but you could try to use the general three.js functionality to display some dynamic elements (text ...)
This extension is supported by the PTC lab so for question you can contact them directly lab@ptc.com
Another point is that you mentioned the live data is possible in Creo View and thingview. Im really not sure if this will work. May be it could work in Creo View Toolkit but as mention there is not directly such functionality. In the Creo View toolkit the only type of markup you can create in the 3D view is leader lines.It will get expanded to others such as notes so that we can expect that this could work. As webgl iss not using plugin technology they could always render html over the top of the webgl canvas. But people would be on their own if they do that.
