# n(f) - Alternate Origin

```
n(f) = { <yappGlobalOrigin>, yappAltOrigin } // Only affects Top(lid), Back and Right Faces
```

Specifying yappLeftOrigin will invert the x-axis if on the lid, back or right faces. &#x20;

These faces normally have the x axis starting at the right end (if you are holding the box with that face facing you).  This is to have them match up with the opposite face of the cube. &#x20;
