CFrame

CFrame stands for Coordinate Frame. It contains movement and rotation into a UserData item. It can be used for many things such as accurately placing a block or basepart. It is different from position, because it can overlap other parts and can be rotated. Position via properties does not offer the same.

part.CFrame = CFrame.new(5, 8, 1) --for example, places the block "part" at 5,8,1 in the Workspace.
