[BLDG-SIM] gbXML CAD data into eQuest?



All,
 
Recently I have been successful on a number of projects exporting gbXML building geometry from CAD (Autodesk Building Systems 2007) and importing into version 6 of Trace 700 and version 4.3 of Carrier HAP. 
 
Have also tried sending the gbXML to Green Building Studio and downloading the DOE-2 file they create in an effort to import this data expeditiously into eQuest.  Unfortunately the DOE-2 file created by Green Building studio is problematic for use in eQuest -- Jeff Hirsch has looked at one made the following evaluation:
 
It appears that the ACad -> gbXML software creates a building model that is not easily used in eQUEST and cannot ever be used in the eQUEST wizard, only in the detail mode. Since it uses an "Energy Plus" style of input model description (i.e; surface geometry but no floor plan or space layout) it is not really compatible with eQUEST for detail envelope or space/zone modification without some difficulty ... since you cannot use eQUEST 2-d view (the primary way of identifying and modifying space/zone data.)

Also, the building geometry is not correct and is difficult to really confirm in eQUEST ... all the interior and exterior walls extend outside the roof or the roofs are misplaced at Z low by a couple feet.

Since the creation process does not create any space (room geometry) but only physically places walls at the site relative the location of the building on the earth (i.e, it does not geometrically describe the spaces so that they can be viewed in 2- and 3- dimensions, checking the placement of walls is not possible (but there are visual problems such as the wall height I mentioned earlier.)

 
Does anyone know of an expeditious way to transfer gbXML geometry data into eQuest accurately -- being able use the wizards I could live without, so long as space / zone modification possible in detail edit mode.  Or alternatively, does anyone know if gbXML import is "in the works" for a future version of eQuest?
 
Thanks
