Antw: Re: [EnergyPlus_Support] Base surface does not surround subsurface

["Christian Schiefer" <christian.schiefer@xxxxxxxxx>]

Hi Linda,
I didn't unterstand this behavior. The original coordinates are in LLC, CCW.
You have changed the starting point only to get rid of the warning. But you can't say the vertex 4 is the lower left! Because the surface is horizontal and the docu says that for horizontal surfaces the starting point doesn't matter. Or is the statement in the docu simply wrong?

Hi Christian,

I believe it's that your roof coordinates are not in the LLC, CCW, relative 
terms as set in the surfacegeometry.

If you put the roof in as:


SURFACE:HEATTRANSFER,
     G.000.Roof.5,            !- User Supplied Surface Name
     Roof,                    !- Surface Type
     massive roof,            !- Construction Name of the Surface
     G.000,                   !- InsideFaceEnvironment
     ExteriorEnvironment,     !- OutsideFaceEnvironment
     ,                        !- OutsideFaceEnvironment Object
     SunExposed,              !- Sun Exposure
     WindExposed,             !- Wind Exposure
     0.0000,                  !- View Factor to Ground
     4,                       !- Number of Surface Vertex Groups -- Number 
of (X,Y,Z) groups in this surface
     -4.000000000000000e+000,9.999999999999998e-002,3.000000000000000e+000, 
!- X,Y,Z ==> Vertex 4
     0.000000000000000e+000,0.000000000000000e+000,3.000000000000000e+000, 
!- X,Y,Z ==> Vertex 1
     0.000000000000000e+000,4.100000000000000e+000,3.000000000000000e+000, 
!- X,Y,Z ==> Vertex 2
     -4.000000000000000e+000,4.100000000000000e+000,3.000000000000000e+000; 
!- X,Y,Z ==> Vertex 3

The error message goes away.

(Note I just used yours so the Vertex comments are incorrect).
