Generative design
Definition
Generative design is software that produces many design options from goals and constraints, such as loads, keep-out regions, materials, and manufacturing methods. It optimizes toward performance targets rather than following a text description of a shape.
Also known as: generative design software, generative CAD

How it differs from text-to-CAD#
In generative design, you define what the part must do and where it can exist, and the solver works out the shape. PTC describes its Creo tools as optimizing designs based on constraints and requirements, including materials and manufacturing processes, and its example projects use generative topology optimization.
Text-to-CAD starts from a description of the shape itself. The two solve different problems: generative design is for lightweighting and structural performance, and text-to-CAD is for getting an editable starting model quickly.

Topology optimization
Topology optimization is a simulation-driven method that removes material from a design space while meeting stiffness or strength targets under defined loads. The results are often organic shapes that need interpretation or rework before they can be manufactured.
FEA
FEA predicts how a part behaves under loads, heat, or vibration by dividing it into small elements and solving the physics for each one with the finite element method. It is also the engine behind topology optimization and most generative design tools.
Text-to-CAD
Text-to-CAD is AI that turns a natural-language description into editable CAD geometry, such as a STEP file, a parametric model, or CAD code. The goal is a model with exact faces and dimensions that can be modified and manufactured, not just a shape that looks right on screen.
