A CAD file may include which of the following?

A CAD (Computer-Aided Design) file has the capability to include a wide variety of elements that facilitate precise design and drafting tasks. One of the strengths of CAD files is their ability to incorporate both raster data and vector information in the form of layers. Raster data, which consists of pixel-based images (such as photographs or scanned maps), can be used for background reference or to overlay design elements onto real-world imagery. Layers in CAD allow designers to separate different types of information, making it easier to manage various aspects of a project, such as structural elements, mechanical components, or electrical layouts.

The versatility of CAD files in handling both raster data and layers supports complex design workflows where multiple types of information must be integrated and analyzed together. This combination enhances the overall functionality and usability of CAD software in professional environments, enabling efficient project management and collaboration.
