AI / CAD Automation / Product Workflow

PJT - From Idea Sheet to 3D

Mission focused on building an AI workflow able to analyze a product idea sheet and convert it into an initial 3D model, reducing the gap between written intent and usable geometry.

Objective

Translate a fiche idee into a first CAD-ready concept.

Approach

AI-assisted parsing, structured parameters and automated 3D generation logic.

Signal

Strong bridge between engineering definition, software workflow and design output.
