print(game.Workspace.Part.CFrame:pointToObjectSpace(game.Workspace.BasePlate.Position)) print(game.Workspace.Part.CFrame:toObjectSpace(game.Workspace.BasePlate.CFrame).p) --These both print the same thing.
Yes there is a difference, they will be the same thing because it's world coordinates, HOWEVER, one is Vector3 and one is CFrame, so their type is different.
