Abstract: A spatial query language for building information models enables the spatial analysis of buildings and the extraction of partial models that fulfill certain spatial constraints. Among other features, the developed spatial ...

Abstract: Parametric modeling is a well-established methodology in the field of mechanical engineering. It allows for the creation of flexible geometric models using parameters for dimensions and makes it possible to define numeric ...

Abstract: Product data management (PDM) systems are well-established in the manufacturing industry. They form the standard solution for the central storage of all data relating to a product and the processes involved in its manufacture. ...

Abstract: Semantic enrichment of building models adds meaningful domain-specific or application-specific information to a digital building model. It is applicable to solving interoperability problems and to compilation of models ...

Abstract: The design intent and many meaningful semantics in building information modeling (BIM) models are often implicit, and some explicit semantics are lost during model exchanges. The missing information can be artificially ...
