Ruler,Scale

The measurement of plan and modeling requires the switching use between the long ruler and scale. Occasionally s wrong scale could destroy everything. To prevent this from happening, I have combined the ruler and the scale in one, plus the metal side will allow users to directly cut with any scale without having to change the ruler and the tragedy of wrong scale.
