To make you comfortable: If you know Inventor, Fusion 360, SolidWorks or any of the other mainstream CAD packages, you know that everything starts with a 2D sketch that then gets extruded into a 3D shape. And, with enough practice, you can model just about anything you want, as long as you know what the best design will look like.
To make you even more comfortable: Generative Design is super easy to use, AND it does not care if you dont know what the best design should look like. You tell it the problem you need to solve, and then Generative Design will provide you with a number of design solutions so you can explorer different and better options.
This video will show you the steps so you can understand what Generative Design does…If not, well then please let me know…Have an awesome day! Best, Lars
