ROOM MODEL EXTRACTION DEVICE, ROOM MODEL EXTRACTION SYSTEM, ROOM MODEL EXTRACTION PROGRAM, AND ROOM MODEL EXTRACTION METHOD

摘要

An extraction unit (120) extracts a starting component from a BIM (40) that is a building information model. The extraction unit (120) searches for a plurality of building components adjacent to each other, with respect to the BIM (40), by starting from the starting component, and extracts a virtual room constituted by virtual members from the BIM (40) by placing a virtual member on each of a plurality of building components obtained as a search result. The creation unit (130) sets, for each of the virtual members in the virtual room, a piece of attribute information associated with the building component on which the virtual member is placed from among pieces of attribute information included in the BIM (40), and creates a virtual room, in which pieces of attribute information are set, as a room model (51).
