Brad has been developing computational design tools for advanced manufacturing for 10+ years.

Talk Abstract: Generative Design – Functional Modelling:
Functional modelling, or the idea of features being stateless is not a new paradigm, however it has yet to be applied to mechanical CAD. For the last 30 or so years, Feature based modelling has allowed us to model with a limited set of parametric traits: mainly geometric constraints. Generative being the next paradigm for MCAD presents an opportunity to now make everything parametric — from how you locate a point, to how you map a lattice to a surface. For this to work, however, each function needs to be independent & stateless, that is, for a set of inputs it will produce one set of outputs. Linking a number of these functions together can allow the “modelling” of a part or the definition of an assembly.
