Is it possible to mirror the OpenStudio space geometry?

I have created a completed OpenStudio model of a prototypical building. I need to model this building in various locations (easy part) and in some cases with the building mirrored (difficult part). I have been unable to successfully mirror the building geometry. I have tried to mirror the geometry by the scale button, and it appears to work. However, once I close out of Sketchup and open the model back up in Sketchup, the zones are discombobulated. It seems that the OpenStudio spaces do not play well with being mirrored (even though it is possible to do in Sketchup), unless it is a simple translation (moving or rotating).

Has anyone been able to successfully mirror building geometry (OpenStudio spaces) in Sketchup?

Depending on what you mean by mirroring the building, you might be able to use the Building North Axis field to rotate the entire building 180 degrees. Otherwise, if you want to mirror geometry about a specific plane it would be possible to write a measure to do this.

The scale tool is generally not compatible with OpenStudio, the one exception is that it is used to modify illuminance maps.

Ha! I thought I had written a comment 'this sounds like a measure waiting to be written @macumber' but I guess I didn't press 'Add Comment' or something. Would the measure be any more complicated than taking all X (or Y) coordinates and negating them?

How would I write a measure to mirror my model? I am still new to open studio so I'm not quite clear as to what i actually need to do. My building is complicated with many interior and exterior spaces and I want to mirror the entire geometry is that possible?

You may want to consider the technique shown in this post. It uses the experimental workflow which allows you to work with any native SketchUp tools including scale. The example in this post uses the scale tool to adjust the floor to floor height, but could just as easily scale to -1 on the X and or Y axis.
