A. Generative Design:

Generative design is a revolution in the world of engineering creativity. It is a modern technique that relies on algorithms and digital calculations to generate a wide range of innovative design solutions. Instead of manually designing a single product, generative design allows for the exploration of thousands of design options in a short time, opening up new horizons for creativity and innovation.

Initially, setting the criteria: The designer begins by setting a set of criteria and constraints that the final design must meet. These criteria may include: performance such as strength, weight, flexibility, and the type of materials used and their cost. Available manufacturing techniques. In addition to the general shape and aesthetic details.

A computer algorithm that reflects these criteria and constraints is developed. The algorithm creates 3D models of potential designs based on these criteria. Then, the designs that are generated automatically are evaluated based on the specified criteria. These designs are classified and the best solutions that achieve the optimal balance between all criteria are identified.

The designer can modify the criteria and algorithm to improve the results. Human input can also be integrated into this process to add a personal touch to the final design.

Generative design can be used to create complex and energy-efficient architectural structures. It can also be used to design everyday products such as chairs, furniture, and shoes. And complex spare parts using additive manufacturing techniques such as 3D printing."
