Re: [EnergyPlus_Support] Re: shadowing calc errors (IDF Geometry Viewers)
(Sorry to jump in late here)
For completeness, there are also 3 other IDF geometry viewers that I am aware
of:
WinEPDraw (included with the EnergyPlus install) will create a DXF output
without running a simulation (run from Start--> Programs . . . or use the
"Drawing File" button in EP-Launch)
DrawBDL and DrawEzPlus also will an EnergyPlus idf file and display it in 3-D.
Contact the developers to verify if they support the current version of
EnergyPlus:
