rogue shading surface

savecancel

Hello,

I am using SketchUp 2016 with OpenStudio plugin 1.10.0. I think I "lost" a shading surface somewhere, and I cannot find it with Inspector, Search Surfaces or OSM Diagnostic Script. When launching OpenStudio/EnergyPlus from within the plugin, eplusout.err contains the following lines:

* Severe * IP: IDF line~14639 Object=SHADING:BUILDING:DETAILED, name=SHADING SURFACE 7, Required Field=[Vertex 1 X-coordinate] was blank. * Severe * IP: IDF line~14639 Object=SHADING:BUILDING:DETAILED, name=SHADING SURFACE 7, Required Field=[Vertex 1 Y-coordinate] was blank. * Severe * IP: IDF line~14639 Object=SHADING:BUILDING:DETAILED, name=SHADING SURFACE 7, Required Field=[Vertex 1 Z-coordinate] was blank. * Severe * IP: IDF line~14639 Object=SHADING:BUILDING:DETAILED, name=SHADING SURFACE 7, Required Field=[Vertex 2 X-coordinate] was blank. * Severe * IP: IDF line~14639 Object=SHADING:BUILDING:DETAILED, name=SHADING SURFACE 7, Required Field=[Vertex 2 Y-coordinate] was blank. * Severe * IP: IDF line~14639 Object=SHADING:BUILDING:DETAILED, name=SHADING SURFACE 7, Required Field=[Vertex 2 Z-coordinate] was blank. * Severe * IP: IDF line~14639 Object=SHADING:BUILDING:DETAILED, name=SHADING SURFACE 7, Required Field=[Vertex 3 X-coordinate] was blank. * Severe * IP: IDF line~14639 Object=SHADING:BUILDING:DETAILED, name=SHADING SURFACE 7, Required Field=[Vertex 3 Y-coordinate] was blank. * Severe * IP: IDF line~14639 Object=SHADING:BUILDING:DETAILED, name=SHADING SURFACE 7, Required Field=[Vertex 3 Z-coordinate] was blank.

The same can be found in eplusout.audit. And in.idf contains the following lines:

Shading:Building:Detailed,
  Shading Surface 7,                      !- Name
  ,                                       !- Transmittance Schedule Name
  ;                                       !- Number of Vertices

This does indeed appear to be an empty surface, when compared to other shading surfaces in in.idf. EnergyPlus will not continue unless this error is resolved. Is there a plugin/ruby user script that can find this rogue shading surface in the .OSM file and delete it?

Thanks,
