.Touched event not working?

Herro, so I'm making a tool that move's models and stuff, and I was wondering why this .touched event wouldn't work while CFraming.

In my script the model is attached to my mouse, and is moving by CFrame (not Vector3). When the model hits a part, it does not print that it actually hit it, why is that?

*But, when I hit my player, it'll print which part of my body I hit. *

IN LOCALSCRIPT

Item.PrimaryPart.Touched:connect(function(hit)
	print(hit)
	-- other stuff
end)

HOW WILL I BE ABLE TO USE THIS WHEN ITS CFRAMED
