Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for interpreting data in a drawing file. A graphics sync module of a system performs synchronization between graphical data in the drawing file and graphical data in a space management database. Each layer of the drawing file includes graphical data used to digitally render items of a floor map. The system identifies a grouping of layers from the drawing file and retrieves values from a space management database (“SMD”) that includes records with values for entities that correspond to items of the floor map. The graphics sync module extracts values of the graphical data for a layer and synchronizes graphical data for different layers of the drawing file with graphical data in entity records stored in the space management database.
