This book explains the core concept of Design Intent, the driving philosophy behind the design of part and assembly models in Creo Parametric. Design Intent recognizes that the initial design phase is only a small part of the lifecycle of a product; we spend more of our time modifying and updating our models. Therefore, we want to build additional information and intelligence into our models, so that when we make changes, those changes are propagated and our models update in ways that we plan for and expect.By understanding Design Intent, you will be able to build models that are truly parametric, robust, and flexible. Furthermore, you will experience less frustration and higher confidence and proficiency as a user.
