This paper discusses the adoption of BIM tools as an opportunity for design generation, validation, and implementation. It specifically focuses on parametric modeling in discussing construction details, assemblies, and generative explorations in the design context. The introduction of parametric thinking into architectural design allows for understanding the interdependencies between various elements of a building assembly and improves an architect's communication with consultants and builders. It also opens doors for "What if⋯" speculative exploration that allow for broader questioning of design intent. This second aspect of parametric thinking encourages students to bridge technical knowledge with creativity.
