FloorspaceJS json north axis not being imported into OS model

[antonszilasi]

I have created a floor space model where I rotated the north axis by -270 degrees/90 degrees (see the jpg below)

This north axis rotation can be seen in the north_axis property of the Floorspace JS json which is produced from the floor space app.

However it appears that this north axis rotation is not be carried forward to the OS model when the Floorspace JS json is converted to a OS model using the following code:

      floorplan = OpenStudio::FloorplanJS::load(json_data)
      if floorplan.empty?
        raise ArgumentError.new("Cannot load floorplan from '#{floorplan_path}'.")
      end

      scene = floorplan.get.toThreeScene(true)

      rt = OpenStudio::Model::ThreeJSReverseTranslator.ne
[floorplan90degreesRotated.zip](https://github.com/NREL/OpenStudio/files/3340088/floorplan90degreesRotated.zip)
w

      model = rt.modelFromThreeJS(scene)

As the north axis of the OS model is set to 0.

Could you please confirm that this is the case, and if it is could you please fix this issue in the Openstudio api ASAP.

I have attached both the FloorSpace JS json and the OS model created from it in the zip file.

Thank you!
