Within a single model, you can create groups and freely drag/drop parts between those new groups. However you cannot drag parts from one model into another model. They are viewed as separate entities in the Visualize scene tree.
Copy/paste parts and moving parts between models hits the core of Visualize code, so it's not as easy as it sounds. This has been a feature requested by several customers, so we have prioritized it accordingly and will look into it.
Thanks for bringing it up here; now we can add another tick in that box for this feature request

This is useful to know, but strictly for the purposes of visualization, you can import the same model numerous times, isolate the parts of interest and disable all of the other parts. You can then move it about your environment as you see fit. It's a clunky work around, but works well enough.
