Model Based Definition enables the production of a complete digital definition of a product within a 3D model, thus replacing a traditional drawing. By empowering the model as the single source of truth product teams are able to save valuable time by incorporating product and process information and ensure that intent is completely captured and associated to the model. Compared to drawing-centric workflows, NX reduces the time spent on engineering documentation, drives downstream tools for validation and manufacturing, and reduces late changes and scrap. With one source of dimensional and tolerance information, there’s no need to worry about drawings and models not agreeing with each other. In addition, annotated 3D models are easier to understand than complex drawings, reducing training needs and the chance for errors.
