Explore and generate organic shapes, on target, with a solution for Additive Manufacturing, also addressed to traditional manufacturing. The Function Driven Generative Designer role allows the designer to capture all functional specifications: geometrical inputs, but also analysis inputs, optimization target and constraints. The Generative aspect comes from the modeling reduction in this process. Concept shapes are generated from a simple push button to obtain an exact representation, and we can easily validate the structural behavior of this concept. With such a design study, the Designer can easily create, visualize, compare different variants and their resulting KPIs to perform a trade-off and select the best concept. This workflow is also based on the manufacturing constraints defined upfront, and handles Additive Manufacturing along with more traditional processes such as milling, cast and forge … As the Designer moves on to Detailed Design, he has at his disposal different sets of capabilities to assist him with the detailed modeling of the part, which can still easily be structurally validated before moving to manufacturing.
