# Coordinates in Openstudio Geometry are mirrored

I noticed this problem after adding shading surfaces to the model.

The x and y coordinates appear to have flipped sign when viewed in the geometry tab.

This surface should have coordinates with negative x value, negative y value, and positive z value. However, looking in the osm file as text, the x and y values are the wrong sign.

```

4.011084424, 8.2790292198, 11.5824, !- X,Y,Z Vertex 2 {m}
0.048684424, 8.2790292198, 11.5824, !- X,Y,Z Vertex 3 {m}
0.048684424, 0.0488452197, 11.5824; !- X,Y,Z Vertex 4 {m}
```

Then it gets weirder as my shading surfaces are positioned correctly with their vertices in the geometry tab.

```

```

What's going on? Here is a link to the osm file with this behavior.
