The advent of BIM has brought about a lot of change to architectural design and construction delivery methods. One aspect that has been directly affected (for the better) is an architect’s capacity to communicate design intent. Model‐based communication then, is quickly becoming an important area of focus within the umbrella of BIM. Nowhere is this more relevant than in the back and forth between designers and fabricators or builders. A common workflow in the industry today is the use a BIM as a central repository of a project’s documentation with other platforms providing specialized solutions where needed. A feature based parametric modeling platform such as CATIA is one of these tools and is often used as a means to manage highly complex subsets of a larger structure. This workshop explored the reasons why parametric workflows not only make the digital fabrication process possible, but enhance it.
