Democratization of Generative Design for Decks and Patios With BIM and AI

The main challenge was the low accessibility of generative design tools for non-specialists, despite their potential for efficiency. Existing software was complex and unintuitive, creating a technical barrier for amateur designers and early-career professionals. Furthermore, there was a need to design exterior structures more efficiently, ergonomically, and in compliance with current standards in Canada. Our project overcame this dual challenge by proposing a solution that radically simplifies the process. Instead of requiring users to acquire extensive technical expertise, we developed a framework based on automated assistance logic, which allows a non-technical audience to design exterior spaces tailored to their needs while ensuring compliance with construction and regulatory requirements. The project solved the problem by acting as a "mediator between technical complexity and individual creativity."

The solution developed is a conceptual framework and proof of concept that resolves the challenge through an integrated platform on the 3DExperience Visual Scripting software. The platform stands out for its intuitive interface, which allows non-technical users to design outdoor spaces without prior expertise. Instead of manual modeling, users define a set of functional parameters (dimensions, constraints, requirements) which are then processed by the system. The core of the solution is a modular parametric model and an automated spatial management algorithm. Managing space within space ensures that spatial conditions are considered and used effectively to meet users' real needs. These  elements work together to automatically generate multiple functional design variations that comply with all applicable regulatory and ergonomic standards. The validation of this device, carried out through concrete simulations, demonstrated its ability to produce coherent, adaptable, and customizable proposals. The device thus allows users to engage in an autonomous and informed design process, which was the main objective.
