CBECC-Com Detailed Geometry Surface Azimuth Errors!?

edit

I have created several detailed geometries using both IESVE and SketchUp/OpenStudio for Title 24 simulation using CBECC-Com 2013 and 2016, and have hit dead ends with the following errors:

Error: Trig parameter out of range evaluating rule: Set DEFAULT ExtWall:RealAz (12:'ComponentAreas.rule' line 368) Error: Undefined data: left side of '+' evaluating rule: Set DEFAULT ExtWall:Az (12:'ComponentAreas.rule' line 405) Error: Undefined data: left side of '<' evaluating rule: Set DEFAULT ExtWall:TreeDescrip (12:'ComponentAreas.rule' line 427)

When going to the specified lines in the "componentareas.rule" file, it's quite obvious they are using the calculated azimuth angle for exterior surfaces (typically walls, I believe). And when looking at the file in the CBECC-Com interface, it's also clear that the azimuth angles are not being calculated for some (not all) surfaces. You can tell because the surface does not list the construction assembly assigned to it, which it usually does. And then double clicking that surfaces shows the two azimuth fields, that should be calculated, are blank.

I've checked to see if the polygons are non-planar, but those I checked were in fact planar. I don't know what else to check, but I'm hoping somebody has run into this and developed some kind of fix - either in the original geometry software or in the SDDxml file (ideally the latter so I don't lose the work I've put into my model).

Thanks in advance for any help!
