OpenStudioApplication-1.1.0

I am attempting to view a simple 3zone building model from an IDF file linked here.

  1. I have tested converting to json and validating it against the eplus 9.4.0 json schema - it passes.
  2. When imported into OS, the zones appear in the Thermal Zone tab (see below)

However, it only renders a single zone...what am I missing? TIA

EDIT: Three spaces show up as well.

What does it show on the spaces tab? Spaces are where geometry lives in OpenStudio.

You have surfaces that occupy the same planes. For example, BuildingSurface:Detailed Surface 1 and Surface 13 have the same coordinates. Same with 2 and 14.

Wait sorry. I did know that, BUT in the definition for each of the thermal zones, it defines an x_origin, y_origin, and z_origin. I thought that was like some sort of offset...does it not work like that?

I didn't realize there was a toggle switch in the GlobalGeometryRules for relative vs. world coordinates. The above works as expected when I simply modified:

"coordinate_system": "World" to "coordinate_system": "Relative"
