The Global coordinate system defines the geometry of floor types. The origin of this coordinate system is selected arbitrarily by the user. The X and Y axes are fixed by RAM Modeler and are always in plan, the Z axis is vertical.

The following input and output quantities refer to the global coordinate system:

1. Member coordinates
2. Mass coordinates
3. Nodal coordinates
4. Static and dynamic lateral story forces
5. Nodal loads
6. Story drift and displacements
7. Nodal displacements
8. Foundation reactions.
