Base and Offset are internal properties that are applied to every plate system. They are used to label the two face surfaces of the plate, and no matter what modifications are applied to the plate, the Base and Offset settings never change. This allows the Smart 3D code to keep a consistent sense of direction for every plate, from Molded Forms through Structural Manufacturing. The following illustration shows that the Base and Offset surfaces remain the same even if the thickness direction or offset of the plate’s molded conventions are changed.

The initial Base and Offset settings are determined by the surface normal of the plate, and they are not visible to the user. Surface Normal, Base and Offset are determined at the initial creation of the plate and are not based on the position in the ship; there is no consistent convention based on the plate type or orientation.
