How to changed a part's CFrame to location even if it gets inside parts?

I've been having this question for ever. I clone a part and give it a Cframe, but if that cframe makes it gets inside a part, like a roof because the part is too big it just gets on top of the roof. How do i set it's cframe even if it gets inside other parts?

Make sure the part you are attempting to bind into another part is anchored.

local part = Instance.new('Part', workspace)
part.Anchored = true
part:Clone().Parent = workspace
