Line 10:
Although initially targeted for the geometric information ([[Wire frame model|wire frame]], [[Freeform surface modelling|surfaces]], [[Solid modeling|solids]] and [[drawings]]) of a product, nowadays there are other pieces of information that can be retrieved from a CAD file:<ref name=":05" />
* [[Metadata]] – non-graphical attributes
* Design intent data – e.g . history trees, formulas, rules, guidelines
* Application data – e.g. [[Numerical control|Numerical Control]] tool paths, [[Geometric dimensioning and tolerancing]] ([[GD&T]]), [[process planning]] and [[Bill of materials|assembly structure]]
The different types of product information targeted by the exchange process may vary throughout the life cycle of the product. At earlier stages of the design process, more emphasis is given to the geometric and design intent aspects of the data exchange while metadata and application data are more important at later stages past of the product and process development.<ref name=":05" />
