Case Studies in Parametric Design: A Guide to Visual Scripting in Architecture is a practical reference book for architects, designers, and students looking to build real skills in computational design. Rather than focusing purely on theory, it walks readers through actual case studies that demonstrate how visual scripting tools are applied to solve design problems, giving readers a grounded understanding of parametric design in professional practice. For anyone learning architectural visual scripting, this guide breaks down complex computational modeling concepts into workflows that can be studied and adapted to individual projects. It addresses how parametric methods change the way architects approach form-finding, iteration, and design efficiency, making it useful for readers trying to move beyond static modeling and into dynamic, rule-based design systems. The case study format also helps readers see how these techniques translate into finished architectural outcomes, bridging the gap between software knowledge and applied design thinking. This book suits architecture students, practicing architects, and design professionals who want a clearer, example-driven path into parametric design and visual scripting rather than abstract instruction alone. For readers building a foundation in computational design in architecture, it offers a structured, case-based reference worth keeping close at hand throughout ongoing study or practice.
