It’s tempting when you start a new design to meet the design requirements and call it finished. But the truth is that most products, and CAD designs, undergo changes—both during the development cycle and in later releases. Good engineers anticipate those changes by making smart, deliberate choices at the very start and throughout design.
Follow these tips to future-proof your designs:
Design Intent Characteristics
Design intent is the way you create models so that they behave in a predictable manner when they are modified. It’s essential to give forethought into how your designs are constructed in Creo and consider the product’s entire lifecycle. Doing so will allow you to create robust models and enable you to edit references to features thereby increasing your productivity.
