Introduc)ons
What is this BIM thing? • What exactly is BIM? • Virtual Building • Embedded Intelligence • Simula;on and Analysis • Underlying Parametric and Associa;ve Model
How are BIM and parametric tools related? A Parametric and Associa;ve Model While Revit undoubtedly uses parametrics for these automa7c revisions, unlike fully fledged parametric modelling so<ware such as Pro/ENGINEER, CATIA, or even Sketchpad, the parametric rela7onships of Revit are hidden behind the interface. The focus is on using parametric models rather than crea4ng them. Therefore, while the majority of architecture firms may never use overtly parametric so<ware like Digital Project or Pro/ ENGINEER, most – o<en without even considering it – use parametric equa7ons in some capacity to model their buildings. -‐ Daniel Davis, A History of Parametric Modeling
