CAD software typically stores a wide range of data about a design, including geometric data, such as the dimensions, shapes, and locations of the design's components and features; material data, such as the properties and behavior of the materials used in the design; and functional data, such as the performance and behavior of the design under various conditions.
CAD software also stores metadata about the design, such as its name, creation date, author, and revision history. This data allows users to identify, manage, and track the design and its changes over time.
In addition to design data, CAD software may also store data about the design process, such as the tools and features used, the design constraints and requirements, and the design review and approval status. This data allows users to understand and evaluate the design process, and to identify and resolve any issues or challenges that arise.
