ÂI am a new user to Energyplus, and am using version 8-4. In going through the first example module I added a window on the coordinates of the wallâ??s plane. I have reviewed the DXF file and the model appears fine.Â
However,I am getting a severe error as pasted below.
Questions:
1)   1. Could there be any issues with my input of the window vertices?
2)Â Â Â 2. Is this a detrimental issue that affect the final results? Â

 ** Severe ** GetSurfaceData: Outward facing angle [270.0] of subsurface="EAST WINDOW" significantly different than
  **  ~~~  ** ..facing angle [90.0] of base surface=ZONE SURFACE EAST Tilt=90.0
