The FLS0074.exe file is a Windows self-extracting file made up of three files: aqsa.dwg, aqsaint.dwg, and aqsa.xlg.
The layer with the name "plan" shows the plan of the building, the layers that have the letters "int" in their names show the interior of the building. The remaining files deal with the exterior of the building.
One can view the structure in whichever way one wishes using these files, but I have included two perspective views: one is named "entrance" and it shows the interior of the building as seen from the entrance. The other is named "corner" and it shows the interior of the building from the northeastern corner. These two views can be accessed through the "view" command.
