When you’re exploring multiple design options, you don’t want to be forced to make a decision too early. By using Creo Design Exploration Extension (DEX), you’re able to create multiple variants of your concept design, enabling you to decide which options are right for you. It also means that if you need your design options reviewed by other people in your team, you can send them the options before making a decision.
With Creo DEX, you’re able to send a .tmz file, so that people who need to review your design ideas can access all of your design options. Plus, if they want, it’s possible for them to add their own design options into the file.
