Hi, I'm David Copete

a Licensed Architect living in Orange County, California. I am a Grasshopper script developer, and educator with a passion for parametric design.Throughout my career, I've seen how powerful computational design can be, but I've also seen how overwhelming it can feel to learn. Many architects and students spend countless hours trying to build definitions from scratch, searching through forums, or watching tutorials that never quite solve their problem.

That's why I created DCO Parametric.

My goal is simple: help architects, designers, and students save time while learning Grasshopper through practical, real-world examples.

Every script in this library is designed with the same philosophy I use in professional practice, clean workflows, flexibility, and practical solutions that you can immediately apply to your own projects. Whether you're designing façades, structures, panels, patterns, or fabrication-ready models, my goal is to help you spend less time reinventing the wheel and more time designing.

As a Vault Member, you'll gain access to a growing collection of professionally developed Rhino and Grasshopper scripts, detailed tutorials, and educational resources that continue to expand every month.

Whether you're just beginning your parametric design journey or you're an experienced professional looking to accelerate your workflow, I'm excited to help you create better designs, faster.

Welcome to DCO Parametric.
