Re: [EnergyPlus_Support] IFC to IDF

[Rob Hitchcock <RJHitchcock@xxxxxxx>]

It is always nice to see determined end-users work around software
limitations.

The gap between surfaces should not be a problem for the current thermal
or daylighting simulation methods used by EnergyPlus.  A problem could
occur for a daylighting simulation method based on raytracing or
radiosity algorithms.
