When I export my Revit model by spaces, it creates an XML file that contains walls, openings, etc. But the wall 'height' value is set to wherever the 'space interior fill' ends, which is usually the ceiling. Common load calculation programs need the 'floor to floor' height (or at least floor to bottom of floor above to be most accurate). Is there any way to get Revit to export this more useful value? It is saved on the space object, as Space > Constraint > Limit Offset. Are there any settings for GBXML export anywhere?
Even if those settings are text files or xml settings files, I'm interested (doesn't have to actually be a dialog box full of settings). Thanks.

Usually when you export to GBxml, only Room or Space Volume is calculated. If other Third party require wall height then you may need to ignore ceiling room bouding or create a plenum space between the ceiling and the the floor above it.
You could also try the Export Complixity on the General tab and see if one of these options will export the wall hight
Shading surfaces are not associated with any room/space (roof overhang, free-standing wall).
Mullions in curtain walls are exported as shading surfaces. A simple analytical shading surface is produced from mullions, based on the centerline, thickness, and offset.
1) add another space and mark it as 'plenum' since space separator only work between walls
2) I tried to assign the ceiling to a workset and close it (didn't work)
I Tried with link visibility graphics (didn't Work)
So I guess you need to open the Arch file and uncheck room bounding for ceilings
Since I don't know what the results look like once it is imported into the program you are using, you need to test it. See which of these alternative solutions works better for you.
I guess you need to set a workflow with the architect with the new upcoming project and consider the ceiling as room bounding or not
You could always send a wishlist request to our development team about including more geometry for the GBxml

Great, thank you!
