How Do I check if the terrain is not glitching another part?

So i am making a placement system on uneven terrain and when the player moves an object i want the script to detect if the object is in a placeable. Can i detect if terrain is showing through the object. This is the section of the script that matters;

btw i know how to get rid of the grass strands showing through the model but I don't know how to get rid of the terrain showing through the object

m.Button1Down:Connect(function()
		game.ReplicatedStorage.RemoteEvents.TentEvents.PlaceTent:FireServer(temptent.CFrame, "BasicShelter")
		model:Destroy()
	end)
end)

this script detects mousedown and then it sends a message to the server to place the object on the server, it sends to cframe and the name of the model!

thanks, NSMascot!

Here is the game so far to test out placing the stuff if that helps you resolve my problem: https://www.roblox.com/games/4870364546

Since terrain is generated in cells you could see if the current cell has Terrain. There are plenty of ways to do this, I believe it would be Terrain:WorldToCell, Terrain:WorldToCellPreferEmpty and Terrain:WorldToCellPreferSolid. Then maybe Terrain:ReadVoxels

How to code it? Honestly, not too sure but hope this gives you some direction on where to look.
