But if you need to address a product that already exists, you might just jump right into the existing 3D model and start making changes and looking at different alternatives to solving the challenge.The problem is, most 3D CAD systems aren’t set up well for trying out alternative ideas and keeping track of the key decision points and design branches along the way. Usually, you make your changes to one model version, save them in a separate file, and then try your next alternative, and save another separate file.
