Exporting to IES, roof overhangs

[cbolton]

I'm trying to export the building I've created in Revit MEP into IES but the overhangs on the roof seem to be ignored.

Please see attached file. The original building has a 2m overhang right around and shows up fine in Revit. Without this overhang there is obviously a massive difference in heating and cooling calculations.

Is it possible to import the roof as well?

Cheers,

Chris

Two immediate ideas here:

* Are the Roof Elements set to be Room Bounding? Check for this in the Element Properties dialog for the Roof Elements in question.

* Are you outputting Shading Surfaces from your model? Check for this in Settings -> Project Information -> Shading Surfaces.

Hope that helps,
