A DWG file (also known as a Drawing file) is one of the older Computer Aided Design (CAD) formats and is primarily associated with Autodesk's AutoCAD application. The format started out as a format for storing 2D CAD drawings but has evolved to store other CAD-related data, including full 3D CAD models.
The format stores the core CAD data, such as points, lines, elevations, and other 2D and, in more recent versions, 3D modelling data, along with other important metadata related to the drawing. The DWG format is proprietary and is intended for use with the AutoCAD application only.
Although designed for the AutoCAD application, there are other 3D CAD and modelling applications that can open DWG files. As the format is proprietary and has been updated many times over the years, opening a DWG file with any application other than AutoCAD will be met with varying degrees of success.

PDF documents have been around for many years, becoming the standard format for storing and transmitting documents with rich content such as formatted text, images, tables, and other complex formatting. The format is still under development, with new features being added with each revision.
One of the reasons for its widespread adoption is its ability to store all the required document components, especially fonts, within a single file, allowing the document to be rendered equally on different platforms and devices.
PDF documents are read-only, unless opened within Adobe's own editing software. Support for importing and converting to and from the PDF format is widely supported by document editing software.
