Karl/Dwight,
I checked the IDs for all the slabs making up the door object. Only the frame (that has holes cut out for the glazing) is assigned WALLHOLE. I've attached the 3D script, however this was created by projecting a side view at 90 degrees, then Save 3D Model as in the Libraries and Objects menu. GDL scripting is pretty much beyond my expertise, however I've included the 3D script as requested.
In the meantime, I will try to isolate the outer frame from the mullions to see if that has any affect (in that the holes in the slab could cause the issue).
Thank you for any additional comments that come to mind....on your valuable Sunday.
