Object composite query method using IFC and LandXML based on BIM linkage model

摘要: Abstract Recently, querying Building Information Modeling (BIM) objects effectively in a linkage manner based on shape information using the LandXML schema widely utilized civil engineering has become necessity. However, because and Industry Foundation Classes (IFC) are building object models, respectively, obtaining required when them is difficult. This study proposes an effective BIM-integrated query method IFC by implementing BIM model. Furthermore, types simple language for queries defined. To validate this method, shows integrated attribute value conditions, including shape. By we can conduct use cases such as efficient interference checks that consider objects.
