Standalone or as integration into your existing toolchain

Generative design optimization is the perfect intermediate between CAD environment and engineering simulation software, providing:
Efficiency: Generative design optimization uses advanced algorithms and AI to generate and evaluate thousands of design options in a fraction of the time it would take for an engineer to create and test each design manually. This efficiency saves time and resources during the design process.

Integration: Generative design optimization can seamlessly integrate with CAD environments and engineering simulation software, allowing engineers to quickly and easily incorporate design changes and evaluate their impact on system performance.

Flexibility: Generative design optimization allows engineers to specify design requirements and constraints, such as weight, material properties, and manufacturing capabilities, and generate designs that meet those requirements. This flexibility allows for rapid iteration and exploration of design options.

: Generative design optimization can explore design options that would be difficult or impossible to consider using only traditional CAD and simulation software. This opens up new possibilities for innovation and optimization.
